Design of Industrial Waste Heat Boiler
Abstract: Many industrial processes produce large amounts of high-temperature
gas, direct emissions only pollute the environment but also waste a lot of energy. It
is necessary according to the development level of the flue gas composition and
temperature waste heat utilization technology to reduce flue gas discharge
temperature. According to the heating water to produce steam heat recovery
principle is an effective use of waste heat resources. Against a high-temperature gas
production process, designed a waste heat boiler, with vertical layout, boiler forced
circulation evaporator taken. Economizer for preheating water to the evaporator, the
evaporator produces saturated steam, superheated to generate superheated steam.
Heated water into the drum through the economizer. The water drum through the
descending pipe into the evaporator, where the mixture is heated and then into the
drum soda separating steam and water. Then leads to saturated steam from the drum
into the superheater, the superheater is heated to generate rated pressure superheated
steam. For waste heat boiler and system piping heat transfer surface and a detailed
design calculations, equipment for reasonable arrangement. 450℃ 3.82MPa to
produce superheated steam, the final exhaust temperature is 158℃. Device
efficiency to achieve the best, to achieve the purpose of energy saving.
