At present, the technology of domestic boiler building with a capacity of up to 20 MW at most Russian enterprises still suffers from archaism, left by the former system. The bet on the production of water-tube boilers did not justify itself. All types of fire-tube boilers were discontinued from production. Therefore, many outdated boilers TG-3/95, NR-18, ZIO-60, E-1/9G are currently in operation. But not everything long-standing, which was abandoned, was bad. It should be noted that in the old days there were experienced craftsmen. Steam boilers are highly reliable equipment that has been perfectly worked out by time. They were fed with water without treatment, and the boilers served up to 40 years. During the period of stagnation, Western countries have gone far. They developed designs for pressurized boilers with pressurized furnaces. These are two- and three-way boilers with a sealed firebox. Modern burners have been developed, on which the burner part is combined with a blower fan, there are means of controlling combustion and protecting the boiler from emergencies. Boilers reduce the amount of harmful emissions of nitrogen oxide and carbon monoxide into the atmosphere.
The Western concept of boilers with automated fan burners is simpler. There is no need to install smoke exhausters and regulate the vacuum in the boiler furnace. Western boilers come ready to work and protected by a layer of modern thermal insulation. The boilers produced by us, when installed in the boiler room, were to be brick-lined or covered with a layer of heat-resistant insulation.
Western technologies are entering our lives. Factories are switching to the production of modern equipment and mastering new production technologies. Modern boiler equipment, corresponding to Western models, is produced by ZiOSab CJSC. A series of steel hot water fire-fighting boilers ZiOSab with a capacity of 125 to 5000 kW has long been on the Russian market.
They operate on gaseous and light liquid fuels, have an efficiency of 92-95%, relatively low cost, are equipped with burners from various companies, are in demand and have proven themselves in operation. Having reworked the technical documentation of Finrail (Finland) to Russian norms and standards, the plant mastered the production of three-pass hot-water fire-tube boilers FR16 with a capacity of 0.5-4 MW and FR10 with a capacity of 5-15 MW.
These are modern fire-tube boilers, manufactured in accordance with strict quality and environmental standards. To replace outdated models of hot water boilers ZiO-60 and NR-18, the design department of CJSC ZiOSab developed a water-heating water-tube boiler ZiOSab600VTM. To simplify the procedure for replacing boilers, it was developed, together with the Department for Technological and Environmental Supervision of Rostekhnadzor, the Main Directorate of the Fuel and Energy Complex of the Moscow Region, State Unitary Enterprise MO Mosoblgaz, and CJSC ZiOSab, and approved by the Minister of Housing and Public Utilities of the Government of the Moscow Region, "Regulations on the replacement boilers KVA-0.6G (ZiO-60) for automated boiler units KVA-0.6G/LZh (ZiOSab600VTM) with a capacity equal to the design capacity of the replaced boilers, without increasing the installed capacity and gas consumption of the boiler house.
The REMEKS group of companies (Chernogolovka, Moscow Region) has long been known on the market as a domestic manufacturer of high-quality steel hot-water fire-tube boilers of the Turboterm brand, which began its activity with the production of boilers with a reversible furnace. The technical characteristics of the boilers of this series allow the use of all types of gaseous and liquid fuels, incl. low grade oil.
New requirements and accumulated experience led to the creation of two new series of three-pass boilers - "Turboterm-Standard" and "Turboterm-Garant", designed to operate on gas and light liquid fuel. At present, the production of steel water-heating fire-tube boilers of the Turboterm brand is carried out in the power range from 110 to 7000 kW. JSC "Dorogobuzhkotlomash" (Smolensk region) since 1962 specializes in the production of hot water boilers with a capacity of 10 to 209 MW.
Based on the results of many years of operation of the traditional nomenclature, a package of proposals for modernization with the improvement of technical, economic and environmental indicators has been formed. Among the novelties for the market of medium-sized boilers are tunnel boilers KVGM-7.56-150(115)N and KV-GM-11.63-150 (115)N with compact dimensions, in lightweight insulation and sheathing with laminated sheet, adapted to burners foreign and domestic production.
Over the past 10 years, Dorogobuzhkotlomash has been actively working on the supply of equipment for small-scale thermal power generation. Today, the plant's product range includes more than 40 standard sizes of hot water boilers from 0.05 to 7.56 MW using various fuels:
- Smolensk series, three-pass water-tube gas-tight boilers, which have no foreign analogues. Type order: KV-GM, 1.16; 2.32; 3.48 and 4.65 MW, efficiency - 93.8-95%;
- Dorogobuzh series, fire-tube boilers with reversible furnace. Type order 0.05-2.32 MW, efficiency - 91-93%;
- series "Dnepr", three-pass fire-tube boilers for operation on diesel fuel, fuel oil, oil, represented by the Dnepr2000 boiler, in the development of Dnepr-1200, efficiency - 92.4-92.7%;
- Vacumatic series, new in 2005 - vacuum gas boilers with an extended service life and the absence of TOVP. Type order 0.63-2.0 MW, efficiency - 92%.
Boilers of these series are successfully used for the construction of modular boiler houses MK DKM complete with modern imported burners, pumping equipment, automation. Other domestic plants also switched to the production of modern boiler equipment. But not everywhere things go in a progressive direction, the transition to new technologies is impossible due to lack of funds.
In order for us to enter the foreign market, we need to have our own modern boilers with indicators higher than similar imported ones, designed and manufactured on the basis of imported technologies. In the West, the technology for the production of modern boilers has been worked out for industrial assembly, perfected by time and requires a minimum of costs for their production. LOOS and VIESSMANN companies are distinguished by the highest and highest quality boiler assembly technology.
LOOS offers hot water three-pass fire-tube boilers UNIMAT, type UT, which operate in the power range from 750 to 19,200 kW with a water heating temperature of up to 120°C with a pressure of 6 and 10 bar. Selection of the boiler series covers any customer's heating needs. Boiler efficiency - up to 95% without the use of an exhaust gas heat exchanger. It has low radiation losses and works with burners of all systems, incl. with reduced nitric oxide emissions.
At a return flow temperature of 50°C and a low load limit, the dew point in the boiler is not reached. There are no minimum load restrictions. Unlike similar domestic and Western boilers, these boilers have minimal dimensions and are used to complete packaged boiler houses. Suitable for all types of heating systems. Boilers have no analogues: the difference lies in design when simple optimal reliable solutions are developed, with access for repair and maintenance.
VIESSMANN has launched its range of hot water boilers. These are Vitoplex100 boilers from 80 to 460 kW and from 575 to 1750 kW. Three-pass boilers with an oval-shaped body, which made it possible to reasonably place the furnace flame tube, second-pass flue pipes and third-pass flame tubes. With this arrangement, the compactness of the entire structure is achieved at a low height, which is very important for completing block-modular boiler houses.
Vitoplex-100 - high quality at an attractive price among medium-sized boilers. The nominal efficiency of the boiler is 94%. The layout of the gas ducts of the boiler unit at low tension of the combustion chamber ensures a minimum release of nitrogen oxides. Economical and reliable operation of the heating system is achieved by controlling the digital controller. Boilers Vitoplex-300 with a capacity of 80-460 kW and 575-1750 kW.
The nominal efficiency of the boiler reaches 96%. The boilers are equipped with multilayer contact heat exchange surfaces, which allows the boiler to operate without restrictions on the temperature of the water in the return line. The boiler is expensive and rarely purchased in practice. Restrictions on the return water temperature on Vitoplex-100 boilers are eliminated by installing a recirculation pump. The Vitomax-100 boiler with a reversible combustion chamber with a capacity of 375-1850 kW is not purchased from us.
Boilers of this type are installed mainly of domestic production, which have managed to prove themselves well in work. The three-pass Vitoplex200 boiler with a capacity of 2,100 to 15,000 MW performs well. The nominal efficiency of the boiler is 95%. Provides a minimum amount of nitric oxide emissions. There are no restrictions on the minimum flow rate of the coolant, the reliability of the operation of the heating system is ensured.
In practice, these boilers are rarely purchased in Russia. Boilers of the LOOS company of the UT series are purchased. The Italian company CARIONI NAVAL presents its water-heating fire-tube boiler with a reversible NPR furnace with power from 60 to 4600 kW. Boiler efficiency - 90%. The boiler is made according to modern technologies, reliable in operation, but we have a small demand for these boilers.
The company manufactures three-way serpentine-type hot water boilers with forced circulation of horizontal and vertical execution SMT/AS with power from 116 to 10,000 kW. Boiler efficiency - 91%. When the load is reduced, the efficiency increases to 95%. In the designs of boilers manufactured by French and Swedish companies, the differences are insignificant. The presence of modern highly reliable automated boilers and burners made it possible to really move on to the construction of fully automated boiler houses that operate without permanent staff.
The personnel in them is needed only for the period of commissioning, scheduled inspections, equipment revision, taking readings from instruments, filling complexonate and filling CWT tanks with salt, sampling for analysis and harvesting. Usually the boiler room is closed and operates automatically. Information about malfunctions is sent to the dispatcher. The NPP Progress-1 enterprise built built-in, free-standing, complete-block and roof fully automated boiler houses.
A complete block boiler house is when it is completely assembled at the enterprise and, in the form of separate finished blocks, is transported to the construction site. At the construction site, a boiler house is assembled from ready-made blocks and connected to engineering networks (heating networks, water supply, sewerage, electrical networks, telephone, communications). The assembled boiler room is ready for work. The enterprise has built quite a lot of such boiler houses.
Now the construction of a 15.6 MW boiler house with LOOS UT-5200 boilers is at the stage of completion. There are many boiler houses built with VIESSMANN boilers of the Vitoplex100 type and Podolsk boilers of the ZiOSab type in operation. The technology of boiler houses under construction is different. It depends on the type of installed equipment (boilers), the wishes of the customer and the degree of deterioration of heating networks, heating systems of buildings and industries.
Thermal schemes for boiler houses under construction are accepted as single- and double-circuit ones. Single-circuit schemes with imported boilers are used at facilities where heat supply systems are made at the modern technical level and there are practically no water leaks in them. At the request of customers, boiler houses were built, where a heat carrier of standard parameters is supplied to the heating network (in winter 95 ° C, and in summer 80 ° C).
At the same time, heated buildings are equipped with individual heating points (ITP), where equipment and automation devices are installed for weather-dependent regulation of water temperature in heating systems and for heating water to the required temperature in the DHW system. Forced ventilation systems are equipped with automation to control the heating temperature of the air supplied to the room or maintain the set temperature in the room.
Such heat supply systems with IHS provide more comfortable conditions in heated rooms and save heat by lowering the temperature during non-working hours. For heating residential settlements, where the existing heating networks are worn out and have significant losses of network water, boiler houses with a double-circuit thermal scheme have been built and are operating. In such boiler houses, the boiler circuit is separated from the heating network and has its own boiler circulation pumps.
Network water in the heating network for the heating system is heated by boiler water with a temperature of up to 110 ° C in plate heat exchangers. Water for the boiler circuit is treated by iron removal and Na-cationization to the required parameters. Water hardness is maintained no more than 20 mcg-eq / kg. Network water in the heating system is treated by introducing a complexone. The double-circuit scheme of the boiler house eliminates the possibility of violations of the water regime in the boiler circuit in case of large water leaks in heating networks.
Plate heat exchangers designed for heating network water are also reliably protected. Heat exchangers operate under conditions where scale formation on heat exchange surfaces does not occur. With the production of gas-tight water-tube boilers by factories, there is a problem - how do you know which of the boilers, water-tube or fire-tube, is better? So far, NPP Progress-1 has used only fire-tube boilers in the construction of automated boiler houses.
Information on the production of water-tube boilers with a heating temperature of up to 115°C was not received from foreign manufacturers. The efficiency of boilers, both water and fire tube, depends on the design of the boiler and can reach 95%. For domestic-made boilers, a single-circuit boiler room scheme is usually adopted. The boilers operate on water coming from the heating network, and the network water does not always meet the requirements for their reliable operation. Which of the boilers, hot water or fire tube, will meet the actual operating conditions, time will tell.
The production of reliable and highly economical competitive equipment is not an easy task. This problem is given special attention in the West. At the last meeting with representatives of VIESSMANN, they were shown a 15.6 MW package boiler house with three LOOS boilers. During the conversation, I was informed that VIESSMANN was going to produce boilers similar to those of LOOS. In the West there is tough competition and the strongest wins.
For Russian boilers, despite their progress, the external market for boiler equipment is still inaccessible.
Concern "SoyuzEnergo" has been specializing in the manufacture and supply of boiler equipment for many years, which is an important production unit in the structure of the economy of any country. At the same time, boilers are objects of increased danger, which requires constant maintenance of them in proper condition and audits, which our employees also specialize in.
High (up to critical) parameters, temperature and pressure in which the elements and devices of the boiler operate, require increased requirements for quality and reliability in their production. In addition, the manufacture of boiler equipment is not serial. In some way it is unique, and this is the additional complexity of manufacturing industrial boilers. Concern "SoyuzEnergo" offers the widest range of boiler equipment of its own production, including the most complex, according to customer drawings.

WASTE HEAT BOILERS
Description: Special boilers designed to generate steam or heat water using waste, waste heat energy from devices and units.
Application: metallurgical, chemical enterprises, gas turbine installations.
In recent years, in search of energy sources, scientists are increasingly trying to use the heat that was previously released into the atmosphere, so waste heat boilers have been ordered more and more often. Most waste heat boilers are used in ferrous and non-ferrous metallurgy, in the chemical and coke industry. They are installed behind metallurgical furnaces, in which the exhaust gases contain sulfur oxides and other corrosive substances. The pressure of the cooling medium is selected from the condition that the temperature of the heating surfaces of the boiler must be above the dew point of the flue gases.
Heat recovery boiler KU series
The waste heat boiler of the KU series is designed to generate superheated steam based on the use of the physical heat of the gases leaving the convectors.
The boiler is delivered in transportable units: a drum, a superheater, an evaporator surface, a water economizer, a pipeline within the boiler, a headset and a drum support, a device for sampling steam and water, boiler fittings and drives to it, a frame, casing.
The standard sizes of boilers of the KU series differ in width, that is, in the number of coils connected in parallel in packages. In addition, according to the length of the coil packs, the boilers are divided into two groups: boilers KU-60 and KU-80 have a clear length of gas ducts (lifting - 2850 and lowering - 2600 mm); boilers KU-100 and KU-125 - respectively 3450 and 3150 mm.

UDC 621.18(088.8) Date of publication of the description 13.IV.1965 for teak pipes; resting on an unheated downcomer 7, which goes from the upper collector of the left half of the covective heating surfaces to the lower collector of the right half of the coivective surfaces. The upper collector of the right half of the convective part is connected to the lower collector by an unheated insulated pipe 8.
10 Pipes forming boiler screens are connected to the collectors, divided by internal transverse partitions into separate chambers.
The bottom bottom screen 9 and the top ceiling screen 10 consist of straight pipes.
Horizontally located pipes are connected to the vertical front collectors, shielding the vertical surfaces of the furnace and the reversing chamber, and the screening of the lower part of the furnace to the height of the dividing wall between the furnace and the convective chamber (before the reversing chamber) is carried out by pipes P, covering the perimeter of the furnace, and the screening of the upper part
25 of the furnace and the reversing chamber is made by pipes 12, covering the perimeter of the furnace and the reversing chamber (perimeter of the entire boiler).
The coivetive heating surfaces consist of 18 tube bundles connected to risers
30 convective part.
Transportable water-heating boilers with pipe screens are known, including a furnace, a rotary chamber and a convective part, as well as a lining made, for example, of sheet refractory material, heat-insulating materials and elastic; plaster, fixed to the boiler with bandages.
The purpose of the invention is to reduce the weight of the collectors and thereby reduce the specific metal consumption. This is achieved by the fact that in the proposed boiler, the screen pipes are located horizontally in height: in the lower part of the boiler, up to the rotary chamber along the perimeter of the furnace, and above - along the perimeter of the entire boiler. In order to provide the necessary speed of movement, the boiler is made with a variable section in depth.
The drawing shows a boiler, a longitudinal section.
The lower collectors 1 of the boiler, interconnected, are the support frame. The front vertical collectors 2 of the screens and risers 3 of the convective part of the boiler are connected to the lower collectors. The front collector 4 of the ceiling screen is attached to the upper ends of the collectors 2. The upper manifolds of the 5 coive surfaces are connected to the risers of the coive part.

BOILER
LOMAKINA TYPE TG
Thus, the skeleton of the boiler, consisting of pipes of large diameter - collectors, risers and down pipes, is a solid spatial system and is designed to bear the load from screens, convective surfaces and brickwork.
When arranged with the removal of combustion products downwards, in order to increase the heat transfer coefficient in the convective part, the boiler is made expanded at the front.
The lining 14 of the boiler consists of a lining layer, for example, heat-resistant asbestos cement, a heat-insulating layer, for example, slag wool, and elastic mesh plaster.
In order for the lining not to collapse from shaking during transportation, it is pulled together with bandages attached to the lower frame of the boiler. To distribute the tightening forces under the bandages, slats are placed, which simultaneously fix the layers of heat-insulating materials and prevent them from settling, caking and loss of heat-insulating properties.
In the lining of the boiler there are viewing windows 15 for monitoring the combustion process and removable insulated panels 1b, removing which, you can inspect the convective heating surfaces.
To inspect the screen surfaces during the shutdown of the boiler, the furnace is penetrated through the loopholes for the burners. Explosion valves
17 are installed in the upper part of the boiler.
The specific consumption of metal and the weight of the boiler are the smallest in comparison with other known boilers of the same capacity. Due to sufficiently high speeds and the absence of water sinking in the surface pipes, as well as good mixing of the heated water in the collectors, water boiling in individual sections of the boiler and the associated hydraulic shocks and pipe burnout, as well as internal pipe corrosion during water deaeration are not observed.
Plungers to remove air from the boiler are installed on the upper collectors of the ceiling screen and the upper collectors of the convective part. If necessary, the water circulation scheme in the boiler can be changed by directing cold water from the return line of the heat supply system either first to the screens and then to the convective surfaces, or vice versa. -It is possible to include the convective part between the screens.
The design of the boiler makes it possible to create a celo ry of transportable hot water boilers for preparing hot or superheated water with a heat output from 1 to
15 Gcal (hour). Such boilers can be used in boiler houses for heat supply of buildings15. Boilers with heat output from up to 3 Gcal (hour) can also be used as mobile boilers.
The boiler is fully drainable and suitable for open and semi-open installations. All
2p maintenance of the boiler is carried out from the front.
The fully assembled boiler is delivered bricked to the installation site by railway or on a trailer.

To distribute the tightening forces, rails are placed under the bandages, which simultaneously fix the layers of heat-insulating materials and prevent them from settling, caking and loss of heat-insulating properties. it is possible to inspect the convective heating surfaces. To inspect the screen surfaces during the shutdown of the boiler, the furnace is penetrated through the loopholes for the burners. Explosive valves 17 are installed in the upper part of the boiler. The specific metal consumption and weight of the boiler are the smallest compared to other known boilers of the same capacity. Due to sufficiently high speeds and the absence of water sinking in the surface pipes, as well as good mixing of the heated water in the collectors, water boiling in individual sections of the boiler and the associated hydraulic shocks and pipe burnout, as well as internal pipe corrosion during water deaeration are not observed. Plungers for air removal from the boiler is installed on the upper collectors of the ceiling screen and the upper collectors of the convective part. If necessary, the water circulation scheme in the boiler can be changed by directing cold water from the return line of the heat supply system either first to the screens and then to the convective surfaces, or vice versa. It is possible to turn on the convective part between the screens. The design of the boiler allows you to create a series of transportable hot water boilers for the preparation of hot or superheated water with a heat output of 1 to 15 Gcal (hour). Such boilers can be used in boiler houses for heating buildings. can also be used as mobile boilers. type TG with pipe screens, including a furnace, a reversing chamber and a convective part, as well as a lining made, for example, of sheet refractory material, heat-insulating materials and elastic plaster fixed to the boiler with bandages, characterized in that, in order to reduce weight collectors and reduce the specific consumption of metal, the pipes of the boiler screens are located horizontally in height, in the lower part - up to the rotary chamber along the perimeter of the furnace, and above - along the perimeter of the entire boiler. 2.

For centralized heat supply of large industrial enterprises, cities and individual regions, steel hot-water boilers of high thermal power are used.
Hot water boilers are designed to produce hot water of specified parameters, mainly for heating. They operate on a direct-flow circuit with a constant flow of water. The final heating temperature is determined by the conditions for maintaining a stable temperature in residential and working premises heated by heating devices, through which the water heated in the boiler circulates. Therefore, with a constant surface of the heating devices, the temperature of the water supplied to them is increased with a decrease in the ambient temperature. Usually, the water of the heating network in boilers is heated from 70-104 to 150-170 ° C. Recently, there has been a tendency to increase the temperature of water heating up to 180-200 °C.
To avoid condensation of water vapor from flue gases and the resulting external corrosion of heating surfaces, the water temperature at the inlet to the unit must be above the dew point for the combustion products. In this case, the temperature of the pipe walls at the point of water inlet will also not be lower than the dew point. Therefore, the inlet water temperature should not be lower than 60 °C when the boiler is operating on natural gas, 70 °C when operating on low sulfur fuel oil and 110 °C when using high sulfur fuel oil. Since water can be cooled in the heating system to a temperature below 60 ° C, a certain amount of (direct) water already heated in the boiler is mixed with it before entering the unit.
Gas-oil boilers of the KVGM and PTVM types are most widely used.
Boilers of the KVGM type (Fig. 6) with a thermal output of 4; 6.5; 10; and 30 Gcal / h (4.8-35 MW) have a horizontally located furnace and heating surfaces with direct-flow forced water movement. Specifications are given in table. 5.
Boilers of the PTVM type with a heat output of 30-180 Gcal / h (35-0 MW) are made with a U-shaped (Fig. 7) and tower (Fig. 8) layout. Hot water boilers PTVM-50, PTVM-100 and PTVM-180, made only with a tower layout, have a shielded furnace and convective surfaces located above it. Specifications are given in table. 6.
