摘要
以燃用高炉煤气的燃气蒸汽联合循环发电系统为研究对象,分析了燃气轮机进气温度、负荷和排烟温度及汽轮机负荷之间的关系.当燃气轮机进气温度低于-16℃时,汽轮机负荷降低12 MW;当燃气轮机进气温度超过20℃时,燃气轮机最高负荷约105 MW,比额定负荷低4 MW.燃气轮机进气温度过高或过低均会使系统的经济性变差.采取加热或冷却的措施维持燃气轮机进气温度在合理范围,可实现燃气蒸汽联合循环发电系统经济运行.
Abstract
The study focuses on the gas steam combined cycle power generation system using blast fur-nace gas,and analyzes the relationship between the inlet temperature,load,exhaust temperature,and turbine load of the gas turbine.When the inlet temperature of the gas turbine is below-16℃,the turbine load decreases by 12 MW;When the intake temperature of the gas turbine exceeds 20℃,the maximum load of the gas turbine is about 105 MW,which is 4 MW lower than the rated load.Both high and low gas temperatures will deteriorate the economic efficiency of the system.Adopting heating or cooling measures to maintain the intake temperature within a reasonable range can achieve the eco-nomic operation of gas steam combined cycle power generation systems.
