Abstract: Heat supply reformation of 2伊350 MW gas-steam combined cycle unit in gas filed power plant can solve the heat load
requirements of regional heating. This paper respectively discussed steam extraction modification scheme of intermediate pressure
cylinder, steam verifier scheme, technical characteristics and reform measures of low pressure steam heating scheme, and the
feasibility of the three kinds of schemes combined with the actual situation of power station, which provided a reference for other
similar heating renovation project. Key words: gas-steam combined cycle; heating reform; absorption heat pump; economy
