we are having three number of frame 6B,30MW machines. each turbine compartment is having two no. of BT i.e. turbine compartment vent fans.<pre>
GT1 mark 6 - both fans running, temp is 120degc
GT2 mark 6 - s/b
GT3 mark 6e - with one fan running, temp is 110 degc
-with both fans running, temp is 85degC
above temperature is at fan suction</pre>
mark 6/6e gives turbine compartment temperature high alarm >95degC .
But PCRA (petroleum conservation and research association) suggested to run one only BT fan.
Are temp (>95deg C) are dangerous in long term? and how?
and what may be the reason for temperature differences in case both fans running in GT 1 and 3?
