一种新型液氢动力装置和它的热力学分析

A New Type Liquid Hydrogen Powerplant and Its Thermodynamic Analysis

本文提出以液氢为燃料的新型燃气轮机设计方案,利用液氢的低温能量(低温(?))来预冷燃气轮机进气,同时利用透平排气能量生产水蒸汽,使蒸汽与燃气混合,共同在透平中膨胀作功.这种新型燃气轮机的效率和比功率,都比普通燃气轮机有较大幅度的提高.

The paper suggests a design sketch of new type gas turbine using liquid hydrogen as fuel.It utilizes the lower temperature potential(exergy)of liquid hydrogen to lower the inlet air temperature of the compressor,and at the same time,using the exhaust energy of the turbine to produce steam and mix it with the gas in order to make a expansion work in the turbine. Thus,the efficiency and specific output ratio of this new type gas turbine are increased than those of the common one.
