Dear All, I am estimating a future problem while still in erection phase for 60 MW steam turbine. I may need your help to estimate a solution. Due to some reason my process heater is not able to generate steam at the desired pressure (other parameters including Temperature and Flow rate are remain same). Therefore I want to know the effect of reduce inlet pressure in the HP Steam turbine output. The steam parameters are mention below Steam Turbine is Superheated, Condensing type with Reheater (HP-LP combination) 1. Normal condition Manufacturer : GE HP Steam inlet pressure : 98 bar HP Steam inlet temperature : 365 Degree C Inlet Flow rate : 70 kg/s HP Steam Turbine outlet pressure 23 bar HP Steam Turbine outlet Temperature 220 Degree C There is 1 extraction of steam from the turbine to HP Heater 2 Revised condition HP Steam inlet pressure : 75 bar HP Steam inlet temperature : 365 Degree C Inlet Flow rate : 70 kg/s Can somebody suggest the role of pressure in steam turbine. Will steam turbine able to work properly even at low inlet pressure?
