上海高桥热电厂筹建于1970年,装机总容量为12.5万(千瓦),其中机1、3系C50—95—1型单抽汽冷凝式汽轮机。设计时以供热方式为主。机2为背压机,热网的基本负荷由背压机承担。因为背压机的特点是仅在带最大热负荷时,才达到最大设计出力,因此承担基本负荷时热效率最高。抽汽机有较大的调度灵活性,在热电合供时,可以达到最大设计出力,热、电负荷可在较大范围内分别变动,而效率变化较平稳。因此,承担中间负荷是合适的。为了提高热电厂的运行经济性,就必须使供热量与热网最佳的负荷分配
Shanghai Gaoqiao Thermal Power Plant was established in 1970, with a total installed capacity of 125,000 (kw), of which the machine 1, 3 is a C50-95-1 single-extraction condensing steam turbine. The main heating method is design. The machine 2 is a back press, and the basic load of the heat network is borne by the back press. Because the characteristic of the back press is to reach the maximum design output only with the maximum heat load, the thermal efficiency is the highest when the base load is assumed. The extraction turbine has greater scheduling flexibility. When combined heat and power supply, the maximum design output can be achieved. The thermal and electric loads can be varied within a relatively large range, and the efficiency changes are more stable. Therefore, it is appropriate to bear the intermediate load. In order to increase the economic efficiency of thermal power plants, it is necessary to optimize the distribution of heat supply and heat load.
