we have GE frame5 Model R gas turbine at our plant. We use to run this GT by keeping its turbine, accessory, and load gear compartment doors open. A month ago we closed the doors and afterwards operator observed that compartment temperature had been raised near to trip value of 450F. so,we again opened the door to normalize the temperature in the compartments. Kindly suggest is it in GE design to operate this GT by keeping doors closed or open?
Secondly we are planning to install thermocouples with in the turbine and accessory compartments for online monitoring of temperature on Mark V HMI. this is some thing which is not in the design of This GT. is it feasible? if yes, then what should be the location of thermocouples in compartments? and at what temperature alarm must be configured on these thermocouples?
Also please share the design flow and pressure of pressurizing fan (ventilation fan) which it maintains in turbine and load gear compartments for this model of GE gas turbine. In our case ventilation fan is not working properly.
