George,
is it ok if I calculate efficiency of the turbine by below equation,
1)Enthalpy drop in high pressure turbine (kilowatts) =
(specific enthalpy (Kj/KG) at HP turbine inlet – specific enthalpy at HP turbine outlet) x steam flow rate into turbine (kg/s)
2)Enthalpy drop in each low...
It is 950 only. Because exit steam from high pressure gets reheated and becomes superheated steam and inlet pressure to lp turbine is 950 kpa only. I collected all data from control room only.
George,
I have done some calculations. I have attached sheet. please check and correct me.https://files.engineering.com/getfile.aspx?folder=800951a7-d53c-46c5-92a7-cf713577998b&file=work_-_Copy_-_Copy.xls
georgeverghese,
a) HP turbine - inlet is 1350kg/sec,4134kpag, 225degC, exit pressure ? and exit temp to reheater ?
Exit pressure = 890kPa, saturated , don't have temp gauge at exit.
b) 3 nos of LP turbines running in parallel feed from reheater, so flow per turbine is 450kg/sec, feed...
I have attached one excel file included sketch and High pressure turbine inlet steam pressure is 4.1345 mpag and
225 C temperature. Exhaust pressure from three low pressure turbines are 3.5 kpaA. Flow rate of steam to high pressure turbine is 1300 kg/s. Output megawatts from generator is 860...
I am trying to calculate turbine efficiency. I have one high pressure boiler attached with 3 low pressure boiler. High pressure exhaust is going into reheater and then going into low pressure turbine. Can somebody please help me?
