we have Ge frame 5 5001 P machine, RPM 0-5100, when start up, initial firing also exhaust temperature went high. This is long time pending issue. It's a dual fuel firing machine. In both fuel also same thing happens. From firing to FSNL it takes only 2.3 Minutes. Acceleration rate is 25.5 RPM/sec beyond 2400 RPM. we need smooth start up without exhaust temperature high. Initial FSR rate is set as 38 for liquid and 30 for gas. Total 18 thermocouples are there. Almost 8 thermocouples went high during start up. There is no error in measurement part. No error in valve operation. Can anybody suggest how we can tune the machine for the perfect start up?
We have created thermocouple rejection screen in HMI to avoid start up trip due to exhaust temperature high. I have doubt in start up time, 2.3 minute to reach FSNL. Is that so fast? then what's the optimum acceleration rate of GE frame 5 machine?
