摘要
IGHAT循环把新颖的HAT循环和先进的燃煤技术结合起来，是一种高效率、低污染和低比投资费用的燃煤发电技术，正待人们进一步去研究和开发，它也将为降低IGCC的比投资费用和发电成本提供一条新的途径[1，2]。本文主要分析了IGHAT循环的性能，研究了主要参数透平前温、压比和湿空气相对湿度对系统效率和比功的影响。
Integrated gasification humid air turbine cycle (IGHAT) combines the novel htald air turbine cycle (HAT) with advanced coal fired technology, which is a promisingway of generating electric power at high efficiency high specific work and low emissions. It also will provide a new method to reduce the specific investment expense and generating electricity cost of IGCC. It is one of the most importallt clean-coal technologies, which has drawn more and more attention. This paper founds the mathematical model of all parts in IGHAT, analyzes the influence of inlet temperature of turbine, pressure ratio and relative hunddity of humid air on the performance of the cycle. From the results, we conclude that parameters influence the cycle performance are so many that the flow and parameters should be optimized simultaneously in the cycle.
