喷射热泵在改造中小型抽凝式汽轮机的实际应用及节能效益

The Application and Energy Efficiency of Using Jet Heat Pump to Reconstruct Small and Medium-sized Extraction-condensing Steam Turbine

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.
