Waste heat boiler is a boiler that generates steam or hot water by using the gas or waste gas, waste liquid in the industrial production process, and the heat from the exhaust of some power machines. Waste heat boiler is an important energy-saving equipment. The exhaust gas temperature of various smelting furnaces and roasting kilns is 650~1250 ℃; The exhaust temperature of power machinery such as gas turbine and diesel engine is 370-540 ℃. Installing a waste heat boiler to absorb part of the heat in these exhaust gases can significantly improve the heat utilization rate of the whole system. For example, after installing waste heat boiler in steel rolling heating furnace, the heat energy utilization rate of the whole system can even be increased by about one time.
