M701F型燃气蒸汽联合循环机组启停过程经济性分析

Economical Analysis on the Start-up and Shut-down Process for a M701 Gas-Steam Combined Cycle Unit

介绍了深圳前湾燃机电厂燃气轮机及联合循环机组在两班制运行方式下的启停过程,对机组启停过程中消耗的厂用电和燃料气用量进行了统计和分析,并对机组运行方式进行了比较,指出尽可能以热态启动代替温态启动,可提高机组的经济性。

The start-up and shut-down process of the gas turbine the gas-steam combined cycle unit in Shenzhen Qianwan Gas-turbine Power Plant have been described in the operational mode of two shifts.Based on the statistics analysis of the consumed house power and fuel gas during the start-up/shut-down process of the unit and by comparison of the operational modes,the hot starting may be adopted as far as possible instead of warm starting so as to improve the economy of the power unit.
