一、20万kW汽轮机运行状况回顾20万kW机型预计到1991年底,累计汽轮机产成120台,其中投运110台,在今后一个相当长的时间内仍将是我国电网系统的主力机组。现在已运行的三缸三排汽汽轮机,属于超高压一次中间再热冷凝式,进汽参数是:130绝对大气压、蒸汽温度535℃,再热温度535℃,通流部分为:37级。其中高压缸:-单列级+11压力级中压缸:15压力级低压缸:2×5 末级叶片长度:665mm(东方公司680mm) 随着电子技术、计算机技术等新技术的发展,该型机组经过将近10年的完善化工作,在设计、制造、
First, the 200,000 kW turbine performance review 200,000 kW models are expected by the end of 1991, a total of 120 units of steam turbines, of which 110 units put into operation for a long time in the future will be the main power grid system in China. The three-cylinder three-row steam turbine now in operation belongs to an intermediate reheat condensing type of superhigh pressure. The inlet steam parameters are: 130 absolute atmospheric pressure, steam temperature of 535 ° C and reheat temperature of 535 ° C. Among them, high-pressure cylinder: - single-stage +11 pressure medium pressure cylinder: 15 pressure-level low-pressure cylinder: 2 × 5 last-stage blade length: 665mm (Oriental Company 680mm) With the development of new technologies such as electronic technology and computer technology, Unit after nearly 10 years of improvement work in the design, manufacture,
