we have this boiler built around 35yrs ago and still working on its BMCR. During our operation we experienced a huge drop of pressure from its drum to superheater for about 70-80psig. May I ask if what is the probable cause of this?
Safety valves on drum is set higher than superheater safety valve and no leaks on the system.
Boiler specs:
type: water tube
capacity: 300kpph
pressure: 300psig
usage: power for steam turbines
location: Philippines
last time repaired: 2016- re tubing of bank tubes
control system: manual and plc
