摘　　要：本文分析了用于燃气轮机系统的冷却技术,对采用空气冷却技术的GE-9FA,GE-9G型燃气轮机以及采用蒸汽冷却技术的GE-9H型燃气轮机进行了设计工况点的校核,通过定量计算重点研究了采用两种不同冷却技术的燃气轮机整合到IGCC系统中对系统热力性能、系统参数优化规律及环保性能的影响,从而为研究高效、环保的IGCC系统提供有价值的参考。This paper analyzes the cooling technologies used in gas turbine system, then calculates and checks the design point parameters of GE-9FA, GE-9G type gas turbine with air cooling technology and GE-9H type gas turbine with steam cooling technology. Based on lots of quantitative calculations and analyses, effects of gas turbine with two kinds of cooling technologies on the thermal performance, system parameters optimization rule and environmental performances of Integrated Gasification Combined Cycle (IGCC) system have been studied. Some conclusions obtained here will provide the valuable reference for further study of IGCC system with high efficiency and friendly environmental performance.
