Integrated gasification humid air turbine cycle (IGHAT)combines the novel humid air turbine cycle (HAT) with advanced coal fired technology, which is a promising way 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 important 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 humidity 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.
