不同掺氢比例下联合循环机组热力性能分析
Thermal Performance Analysis on Gas-Steam Combined Cycle Units with Different Hydrogen Doping Ratios
摘要
Abstract
With the GE 9FA gas-steam combined cycle unit being taken as the research objective,a three-pressure reheat combined cycle unit model is established based on Thermoflex commercial software,and the thermal performance of the unit is analyzed under different hydrogen doping ratios in terms of load rate,inlet temperature,waste heat boiler parameters and turbine back pressure.It is showed that with the initial gas turbine inlet temperature unchanged,the efficiencies of both top cycle and combined cycle would increase with the raise of the hydrogen doping ratio,while the temperature and flow rate of exhaust gas would decrease;the efficiencies of both top cycle and combined cycle would increase with the raise of the unit load rate;with the increase of inlet temperature,the efficiency of top cycle would decrease,while the efficiency of the combined cycle would increase;the efficiencies of the combined cycle would increase with the increase of steam temperature and pressure of the waste heat boiler,and would decrease with the increase of the turbine back pressure.The research results can provide reference for design and optimization of gas turbine units with hydrogen doping.关键词
