摘　　要：针对20MW级HAT回热循环燃气轮机试验系统中竖向布置燃烧室需求,参考某型机车燃气轮机双筒燃烧室,开展空气引导机匣优化设计,结合燃烧室实际参数对空气引导机匣开展数值计算分析,考察空气引导机匣的强度分布。计算结果表明,空气引导机匣结构强度及法兰密封性满足要求,可支撑HAT循环试验测试。In order to meet the requirements of the vertical combustor arrangement in the 20MW HAT regenerative cycle gas turbine test system,the optimal design of the air-guided casing was carried out with reference to the twin-tube combustor of a gas turbine for a certain locomotive,the strength distribution of the air-guided casing was investigated by numerical calculation and analysis based on the actual parameters of the combustion chamber.The results show that the structural strength and flange tightness of the air guide casing meet the requirements and support the HAT cycle test.
