摘　　要：本文应用喷射热泵将抽凝式汽轮机改造为低背压汽轮机,并用实例介绍了改造方法设计计算以及关键技术,从而消除冷源损失,达到节能减排的良好效果。This paper introduces how the jet heat pump could reconstruct an extraction-condensing steam turbine to a back-pressure steam turbine.We also provide specific example to explain how to design and calculate reconstructed requirements,as well as key technologies.As a result,we eliminate cold source loss and achieve energy saving and emission reduction.
