摘　　要：燃气轮机在配置盐雾系统的试验台上,模拟海洋盐雾环境下机组长时间运行,通过计算得出折合低压压气机转速、折合高压压气机转速、折合高压压气机后空气压力、折合低压涡轮后燃气温度。根据分析在同一折合高压压气机转速下,折合低压压气机转速出厂时与运行后存在转速差,折合高压压气机后空气压力出厂时与运行后存在压力差,该转速差及压力差均可表征压气机的污染情况。在此基础上完善了运行规范关于水清洗时机的规定,该方法已广泛应用于海洋用燃气轮机,对于燃气轮机运行维护具有重要意义。The gas turbine operates for a long time in a simulated marine salt spray environment on a test bench equipped with a salt spray system.The equivalent low-pressure compressor speed,equivalent high-pressure compressor speed,air pressure after equivalent high-pressure compressor,and gas temperature after equivalent low-pressure turbine are calculated.According to the analysis,at the same equivalent high-pressure compressor speed,there is a speed difference between the low-pressure compressor speed when it leaves the factory and after operation,and a pressure difference between the air pressure when it leaves the factory and after operation when it is equivalent to the high-pressure compressor speed.This speed difference and pressure difference can both characterize the pollution situation of the compressor.On this basis,the operating regulations on the timing of water cleaning have been improved.This method has been widely applied to marine gas turbines,and the operation and maintenance of gas turbines are of great significance.
