Beschreibung
Zusammenfassung:The invention provides a supercritical complementary energy and waste heat cooperative power generation system of an iron and steel plant and a working method of the supercritical complementary energy and waste heat cooperative power generation system, which are used for recycling valuable waste heat steam generated by a boiler of the iron and steel plant to a complementary condensing type turboset for power generation. The boiler comprises a blast furnace gas boiler for generating supercritical ultrahigh-temperature steam, a medium-pressure waste heat boiler for generating medium-pressure superheated steam, a low-pressure waste heat boiler for generating low-pressure superheated steam or low-pressure saturated steam, a medium-pressure steam superheating device and a low-pressure steam superheating device; supercritical superhigh-temperature steam generated by a blast furnace gas boiler is conveyed to a high-pressure cylinder of a steam turbine, and is changed into medium-pressure superheated steam after acti
