Hi,
In my company there is two type of gas turbine:
1. DLN1 TYPE: Frame 9 Mark V
Water injection Type: Frame 9 Mark V
When DLN1 Type working the exhaust gas temperature is higher than the Water injection Type. after that this two type of gas turbine used for HRSG boilers and in each boilers there is a supplemental burner that after this burner there is three thermocouples to sense the gas temperature after this burner so in boilers work with Water injection Type gas turbine. there isn't any problem around the difference between these three thermocouples but the boilers work with DLN1 TYPE. these thermocouples have a difference about over than (50 dc)that cause trip the boilers .
I think when the exhaust gas temperature in DLN1 type is higher than the Water injection Type these thermocouples has a problem. Am I true?
The Water injection Type's gas turbine don't work with water injection. All of time it works without water injection. because I think when this works with water injection, the combustion chamber will destroy. and I want you guideline me about that to find a way to reduce the nox without water injection.
Thank's a lot.
