某工业型燃气轮机油门故障及防喘放气温度试验研究

Experimental Study on Throttle Failure and Temperature of Anti-Surge Deflation of an Industrial Gas Turbine

某工业型燃气轮机在运行过程中出现了油门不受控故障,故障均发生在燃气轮机防喘放气功率区间。通过箱装体空气温度试验研究,在5%~30%功率区间箱装体空气温度升高较快,而当燃气轮机功率升至30%功率以上,防喘放气阀关闭后,箱装体空气温度急剧下降。为避免防喘放气直接排入箱装体内,对防喘进行了引气管路优化,放气区间箱装体截面温度最高约40℃,满足电气元器件的工作温度要求,同时降低了箱装体外空气噪声,优化了运行人员工作环境。

During the operation of an industrial gas turbine,the throttle was out of control,and all the faults occured in the gas turbine anti-surge and deflation power range.Through the experimental study on the air temperature of the box body,the box body temperature rose rapidly in the power range of 5%~30%,but when the gas turbine power rose above 30%and the anti-surge and deflation valve was closed,the box body air temperature dropped sharply.In order to prevent the anti-surge air from being discharged directly into the box,the air induction pipeline for anti-surge was optimized,and the maximum cross-section temperature of the box in the air venting section was about 40℃,which met the working temperature requirements of electrical components.Meanwhile,the air noise outside the box was reduced,and the working environment of operators was optimized.
