Influences of Clean Syngas Preheating Temperature on IGCC Power Plant Performances

Abstract:

400 MW IGCC power plants were modeled by using commercial software GT PRO. The high pressure unsaturated water extracted from heat recovery steam generator (HRSG) was used to heat clean syngas to various temperatures. The influences of clean syngas preheating temperature on plant performances were investigated. Results showed that net power output and coal consumption both reduced with the increase of syngas preheating temperature, and coal consumption reduced to a larger extent. Moreover, when syngas preheating temperature increased, the net electric efficiency increased and the net heat rate decreased gradually. It was concluded that preheating clean syngas in a reasonable way was beneficial to improve the performances of IGCC power plant.
