Description
Steam boiler BKZ-75-39 GMA is designed to produce superheated steam. Drum boiler, with natural circulation, with chamber combustion of fuel. The arrangement of heating surfaces is U-shaped. In the boiler, water is heated, evaporated and superheated. Natural gas is used as fuel. The boiler is designed for operation in closed rooms. Steam capacity of the boiler is 75 t/h, (during reconstruction it is planned to increase the capacity to 90 t/h) absolute pressure and steam temperature is 3.9 MPa, 440 oC, feed water temperature is 145 oC. Heat carrier is combustion products - flue gases. Fuel combustion occurs in vertical combustion chamber formed by screen pipes. Upper and lower ends of pipes are introduced into prefabricated headers. On the front wall of the furnace on two tiers there are three gas-fuel oil burners of the GMU-10 type, with the help of which fuel is burned. In gas-heated pipes forming a furnace and a convective shaft, saturated water vapor is formed. Steam-water mixture is supplied to upper headers, and from them to drum-steam collector and remote separators-cyclones.
