Taking a company as an example, following the principles of matching energy utilization and energy cascade utilization, this paper introduces the recovery and utilization mode of waste heat in each procedure of copper smelting in details. The obtained superheated steam enters the waste heat power generation system to generate electricity, thus the steam heat energy is converted into electric energy. In order to avoid the change of steam grade entering the steam turbine due to the change of process operation in smelting system, a heat storage device is added before the steam turbine. Through the three-stage superposition utilization of the above waste heat, the power generation can reach 200kW·h/t steam.
