I want to show online turbine heat rate in DCS screen of the power plant.Please any one tell me formula(or Algorithm) to calculate enthalpy by using steam pressure and temperature with out using steam table.
sight glass is there in the lube oil return tube line.i confirmed this foaming by seeing this glass only.
but i dont have any problem like air build up in filter housings, pump binding, erratic/unsteady oil pressure.
we are having oil centrifuge pump for oil filtering.we are doing regular oil...
In our power plant rotor earth fault high alarm is coming but if i use spray which i used to clean HT panel breaker in the carbon brush of generator rotor, alarm will go.why?
is it possible to use anti foaming additives in lube oil tank to reduce foaming in lube oil?
I think it will reduce gear box vibration.is it?
has anyone used anti foaming additives in lube oil in their power plant for foaming problem?
our turbine speed is 7059 rpm.this speed is gear box high speed.and gear box low side speed is 1500 rpm. and oil flow in the gear box is proper.but we believe that due to some external factor only this intermittent vibration is coming.because if it is a internal problem means it will be coming...
After doing lots of analysis with vibration specialists we came to know that source of vibration is Gear box of the steam turbine,88 HZ of frequency is coming from gear box.
what are the possibilities of the vibration in the gearbox(internal&external)?.
this vibration is not coming...
In our 30MW steam turbine vibration monitoring system showing vibration reading more than normal level but within trip limit some times.but it is not showing continuously more than normal level reading but not in regular interval also.but we have checked all electrical connection related to...
