摘要/Abstract

摘要： 以某200 MW级燃气-蒸汽联合循环机组为研究对象，利用余热锅炉尾部烟道废热加热给水并通过气-水换热器提高压气机进口空气温度，采用Aspen Plus模拟计算进气加热系统投运前后联合循环参数变化，分析空气进气加热对机组性能影响。研究结果表明，压气机进口空气温度由12.5 ℃提高至35 ℃时，50%、75%、87%负荷下燃机负荷率分别提高0.08、0.12、0.15，燃料消耗量分别降低0.11 kg/s、0.13 kg/s、0.10 kg/s，联合循环效率分别提高1.04%、1.03%、0.73%。95%负荷下燃机负荷率由0.95增大至1.00后保持不变，联合循环效率先增大后减小，100%负荷下燃机负荷率保持1.00不变，联合循环热效率持续降低。

Abstract: Taking a 200 MW-class gas-steam combined cycle power plant unit(GSCC) as the research object, the exhaust heat in the tail flue of the HRSG was utilized to heat the feed water, which was directed afterwards into the gas-water heat exchanger to raise the inlet air temperature of the compressor. The parameter changes before and after the operation of the inlet air heating system were simulated by Aspen Plus and furthermore, the influence of inlet air heating on the performance of the GSCC at partial load was analyzed. Results show that when the inlet temperature of the compressor rise from 12.5 ℃ to 35 ℃ under the load of 50%, 75% and 87% of GSCC, the load rate of the gas turbine increases by 0.08, 0.12 and 0.15 respectively, while the fuel flow rate drops down by 0.11 kg/s, 0.13 kg/s and 0.10 kg/s respectively, and the combined cycle efficiency goes up by 1.04%, 1.03%, and 0.73% respectively. Under 95% load, the load rate of the gas turbine increases from 0.95 to the maximum 1.00, and the combined cycle efficiency increases first before taking a dip. Under 100% load, the load rate of the gas turbine remains unchanged at 1.00, while the heat efficiency of GSCC decreases continually.
