摘要
以PG9171E型燃气-蒸汽联合循环电厂为研究对象,对联合循环及进气冷却系统进行建模。分析了该机组加装进气冷却系统后燃机侧、余热锅炉侧和蒸汽轮机侧系统性能的变化情况。结果表明该E型联合循环机组加装进气冷却系统后,进气温度每降低10℃,燃机侧出力上升约9%,余热锅炉效率下降约3%。通过蒸汽参数的调整充分利用余热资源能使汽轮机多出力2.1 MW,联合循环效率上升约0.3%。
Taking PG9171E gas-steam combined cycle power plant as the research object, in this paper the combined cycle andintake cooling systems were modelled. The performance changes of the gas turbine side, the heat recovery steam generator side andthe steam turbine side of the unit with the inlet cooling system were then analyzed. The results showed that for every 10 degrees ofthe temperature rise, the output of the E-type combined cycle unit with the intake cooling system will increase by about 9 % while theefficiency of the heat recovery steam generator is reduced by 3%. In addition, by properly tuning steam parameters and taking fulladvantage of the waste heat resources the steam turbine will generate more output by about 2.1MW and the combined cycleefficiency can be improved by about 0.3%.
