【摘要】:燃气轮机在全封闭的箱装体中运行时,机匣辐射及法兰处泄漏的热空气会使箱装体内温度急剧升高,而使用双燃料系统时,按照防爆等级要求,附属设备和元件的工作温度不能超过75℃,因此有必要对箱装体进行有效的冷却。对某型燃气轮机在箱装体中的实际运行状态进行数值模拟,并与试验值和场站运行记录进行对比,验证数值模拟方法的准确性,证明现有冷却结构不能满足要求。提出多种冷却结构的优化方案并进行数值模拟,结果表明:分支结构不但可以有效解决箱体内超温的问题,而且可以将冷却空气流量减少29%,将底板附近空气速度减小33%,可在大幅减少对能源的消耗的同时提高底板附近零部件的使用寿命。
[Abstract]:When the gas turbine is running in a fully enclosed tank, the heat air leaking from the casing and the flange will cause the temperature of the tank to rise sharply. When using the dual fuel system, the explosion proof grade is required. The working temperature of accessories and components should not exceed 75 鈩,
