Analysis of steam-injected gas turbine power plant cycle with liquid hydrogen precooling

摘要

In order to utilize the low temperature exergy of liquid hydrogen,the powr plant installs a precooler (heat exchanger) and an auxiliary hydrogen turbine.In the precooler the air which will enter th eocmpressor is cooled by the liquid hydrogen with low temperature.At the same time the liquid hydrogen is heated and evaporated to hydrogen gas by the air with ambient temperature.The low temperature exergy is ocnverted to work by decreasing the compressor input and adding power output of the hydrogen turbine.
