燃气蒸汽联合循环机组供热经济性分析

Economic Analysis of Heat Supply for Gas Steam Combined Cycle Unit

对京西燃气热电机组概况及热网的配置进行了说明,根据目前机组的供电和供热的收入比给出了热电比的平衡点。针对联合循环机组冬季运行的特点,对不同工况下机组实际运行数据分析,给出了不同燃机负荷和不同供热负荷下汽轮机发电量和供热量变化比例关系,确定联合循环机组供热的经济性。

This paper describes the general situation of the Jingxi thermal power plant and the configuration of the heating network. According to the current income ratio of the power supply to the heat supply, the balance point of the thermoelectric ratio is given. On the basis of the characteristics of the operation of combined cycle unit in winter , this paper analyses the actual operating data of the different operating mode. The ratio relationship between the heat supply and the change of the Steam turbine power generation under different gas turbine load and steam turbine load is given . And this paper determines the economic performance of heat supply of combined cycle unit.
