摘要

应用等效焓降法计算分析了CZK150/145-13.2/0.294/535/535型汽轮机组过热蒸汽减温水、再热蒸汽减温水以及热力设备如加热器、疏水泵的投运等对机组能耗的影响。结果表明

再热器减温喷水使机组热耗增加18.56kJ/(kW.h)

较过热器减温喷水时的机组热耗2.20kJ/(kW.h)大很多;隔离高压加热器后使机组热耗增加57.44kJ/(kW.h);隔离疏水泵后使机组热耗增加13.41kJ/(kW.h)。对此

提出了机组运行中应尽量减少再热减温水量

以及尽量保持较高的高压加热器和疏水泵的投运率。

Abstract

Based on the equivalent enthalpy drop method

the influence of factors such as attemperation water of superheated steam and reheat steam

operation of thermal equipments like heater and drain pump on the energy consumption of CZK150/145-13.2/0.294/535/535 type turbine was investigated.Results showed that

reheater attemperating water increased the unit heat consumption by about 18.94 kJ/(kW·h)

which was much more greater than that of the superheater attemperating water(2.24 kJ/(kW·h)).Thus

to keep a higher operation rate of the high pressure heater and drain pump

suggestion that during the unit running the reheater attemperating water should be used as less as possible was given.
