Abstract: With the increase of production capacity and the continuous improvement of energy-saving measures, the amount of
surplus gas in iron and steel enterprises increases greatly. Making full use of secondary energy and efficiently recycling surplus
gas for power generation is the main idea of comprehensive utilization of gas resources in iron and steel enterprises. The mature
and efficient coal-fired thermal power unit technology is transplanted to the gas generator set in iron and steel enterprises, and the
ultra-high temperature subcritical primary reheat technology is adopted to greatly improve the economic level of gas generator set.

Key words: ultra-high temperature subcritical; gas electric power generation; steam turbine; economy
