Beschreibung
Zusammenfassung:	The utility model provides a subcritical complementary energy waste heat recovery power generation system for an iron and steel plant, which is used for recovering steam with utilization value generated by a boiler of the iron and steel plant to a complementary condensing steam turbine set for power generation. The high waste heat equipment comprises a blast furnace gas boiler for generating subcritical ultrahigh-temperature steam, a medium-pressure waste heat boiler for generating medium-pressure superheated steam and a low-pressure waste heat boiler for generating low-pressure superheated steam or low-pressure saturated steam; subcritical ultrahigh-temperature steam generated by the blast furnace gas boiler is sent to a high-pressure cylinder of a steam turbine and becomes medium-pressure superheated steam after acting; medium-pressure superheated steam discharged by the steam turbine high-pressure cylinder and medium-pressure steam generated by the medium-pressure waste heat boilerenter the steam turbine l
