Waste heat power generation project refers to an engineering project that uses sensible heat or latent heat of waste gas, waste water, waste residue and other media produced in industrial production to convert thermal energy into electrical energy through related equipment. For example, waste heat can be used to heat water to generate steam to drive turbine generator sets to generate electricity, such as cement kiln waste heat power generation projects and steel sintering cooler waste heat power generation projects; Some also use the heat generated by waste combustion to drive steam turbines or use gas-steam combined cycle to generate electricity, such as using the waste heat of steel blast furnace gas and coalbed methane to generate electricity.
