STEAM BOILERS

Description: Steam boilers of industrial capacity are devices accumulating the fuel firing energy in the heat-transfer agent, which are water-steam mixture or steam. Practically a boilers is a set of heat exchangers, which are transferring the fuel combustion heat from the boiler furnace to a heat-transfer agent. Fuel is fired in the boiler furnace and the hot gases move through gas pass formed by special
heat exchangers. The first is a superheater, where steam is heated up to 560 ℃ at a pressure of up to 900Mt. Further along the gas flow comes water economizer wherein the heating-system water is preheated and forwarded to the boiler. After the economizer the 100-170 ℃ hot gases are released into atmosphere.
Application: steam boilers are used to drive the turbine-driven generators of electricity, other technological needs, for heating and hot water supply of residential and industrial buildings, at thermal power plants, heat and power plants at steelworks, heat and power plants for chemical and other enterprises.

HOT WATER BOILERS

Description: hot water boilers are used for heating and hot water supply of residential and office buildings, industrial workshops, various ancillary facilities and other commercial buildings. Their principle of operation is almost the same as of the steam boilers, with the only difference water is used as a heat-transfer agent instead of steam, that results in some design differences, in particular the lack of superheater.
Application: water heating, heating and hot water supply of residential and industrial buildings. The water is heated by firing of gaseous, liquid or solid fuels.

LOW-POWER WATER BOILERS

Water boilers of КВ series: КВГМ-1.1; КВ-2.3Г/Ж (ТГМ-2); КВа-3.5-95 (ТГ-3) are used to produce hot water in industrial and municipal heating systems.
The boilers can be used as a part of mobile or stationary boiler installations. A distinctive structural feature of these type of boilers is the lack of special foundations and heavy brickwork envelope. The low-power water boilers are easy to install and operate.

HEAT RECOVERY BOILERS

Description: heat recovery boilers are special boilers intended for generation of steam or water heating using the waste, exhaust thermal energy of various devices and units.
In recent years in search for new energy sources scientists are more often trying to use the heat previously released into atmosphere, so the waste heat recovery boilers are becoming more required. Most of the heat recovery boiler are installed after the metallurgical furnaces in ferrous and nonferrous metallurgy. In ferrous metallurgy the choice of steam parameters is determined primarily by the boiler operating conditions. In non-ferrous metallurgy, sodoregenerating industry and for sulfuric acid production, where flue gases contain sulfur oxides and other corrosive substances, the cooling medium pressure is selected so that the boiler heating surfaces temperature remains above the dew
point of the flue gases.
Application: metallurgical, chemical plants, gas turbine power plants.

HEAT RECOVERY BOILER OF КУ SERIES

Heat recovery boiler of KU series is designed to produce superheated steam through the use of heat accumulated in the gases leaving open-hearth, heating and other technological furnaces. The boiler is supplied divided into transportable units: drum, superheater, evaporating surface, water economizer, boiler piping, boiler drum and accessories and support, water and steam sampling device, the boiler fittings and corresponding actuators, frame, cladding.
Sizes of the КУ series boilers vary in width, that is in the number of parallel coils in batches. In addition, the boilers are divided into two groups by the length of coil batches: first one includes КУ-60 and КУ-80 boilers, which gas passes have the following clear lengths: up- 2850 and down - 2600mm; and the second one includes КУ-100 and КУ-125 boilers with respective lengths of 3450 and 3150 mm.
