摘要
为了达到高效的先进燃气轮机联合循环优化运行,提高循环的能源利用率,以先进燃气轮机联合循环技术为研究对象,通过以有机物为工质的朗肯循环回收燃气轮机的余热,进行燃气轮机联合循环变工况仿真模拟来研究联合循环运行特性,分析了环境温度和压气机进口导叶(IGV)调节对联合循环运行特性的影响,制定了IGV角度的优化控制策略。结果表明:在变负荷工况和不同环境温度下,调节燃气轮机的空燃比,可以优化该燃气轮机联合循环的运行特性,提升联合循环效率。
To optimize the operation performance of advanced gas turbine combined cycle units and improve their energy efficiencies,numerical simulations were carried out under varying working conditions on an advanced unit using organic Rankine cycle to recover the waste heat from the gas turbine,so as to analyze the effects of following factors on the operation performance of the combined cycle unit,such as the ambient temperature and the angle of compressor inlet guide vane(IGV),etc.,and finally to propose a modified IGV control strategy.Results show that under varying load conditions and at different ambient temperatures,the operation performance of the combined cycle unit could be optimized by regulating the ratio of fuel to air,thus to improve its energy efficiency accordingly.
