Abstract
In order to explore the waste heat utilization of the boiler tail gas, which can improve the thermal economy of the power plant and reduce the consumption of the power fuel, the operation characteristics of blast furnace gas boiler are deeply studied, and the energy saving potential of flue gas waste heat of blast furnace gas tail is excavated. Through the comparison of different flue gas waste heat utilization methods, the optimization of tail heating surface is combined with the cascade utilization of waste heat energy resources, the research of efficient flue gas waste heat utilization system is carried out, and the concrete optimization scheme is put forward. It is concluded that after matching, it not only reduces the exhaust temperature of blast furnace gas boiler and improves the thermal economy of the unit and the effect of environmental protection, but also finally has an important significance in the increase of power plant generating capacity.
