关于双工质平行-复合循环热机的新消息通过余热回收蒸汽发生器吸收排气废热,从而产生蒸汽,蒸汽又回注到燃气轮机的燃烧室中,结果是空气-燃料燃烧产物和蒸汽的混合物作为工质在涡轮内膨胀做功并排出。这是双工质平行-复合循环热机的简单描述(详见本刊1986年第四、五期之专题介绍),亦称作加注蒸汽的燃气轮机(STIG发动机)。美国GE公司的付总裁,船舶及工业工程服务部总经理鲍勃·斯沫兰德说:“对LM2500 STIG和LM5000 STIG的加注蒸汽发动机已有第一个订货,发动机将由动力系统工程公司安装在加利福尼亚作热电联供装置。”GE公司称STIG发动机是GE公司船舶和工业部在航空派生的燃气轮机技术方 New information on duplex parallel-compound cycle heat engines Absorption of exhaust waste heat by the heat recovery steam generator generates steam, which is injected back into the combustion chamber of the gas turbine, with the result that a mixture of air-fuel combustion products and steam is used as The working fluid expands in the turbine and discharges. This is a brief description of duplex-parallel hybrid heat engines (see Special Issue, Issue 4, Issue 5, 1986), also known as gas-filled gas turbines (STIG engines). Bob Smashland, president and general manager of shipbuilding and industrial engineering services at GE, said: “The first order has been made for the refueling of the LM2500 STIG and LM5000 STIG steam turbines, which will be installed by Power Systems Engineering In California as a co-generation unit. ”GE said the STIG engine is GE’s Marine and Industrial Division in the air-derived gas turbine technology side
