Thank you Chandan for detailed explanation. Your videos are too much helpful for people who are not from mechanical engg background and working in operations department. Thqnks a lot, keep making such analytical videos.
Very Informative. By increasing only pressure and keeping the same SH temperature, Total Enthalpy decreases. 44 Bar - 400 deg C = 3205 KJ/kg and 64 Bar 400 deg C = 3168 KJ/kg. Please explain how the efficiency increases? Until we get it at the cost of wet steam at LP stages.
Kindly sir would you tell me the about OPC( overspeed protection control)? Is this different from overspeed trip(110%/112%)? If different then what is OPC
I HAVE ONE QUESTIONS THAT, IN BFP THERE IS BOOSTER PUMP TO MAINTAIN SUCTION PR. OF BFP BUT WHY THERE IS SEPARATE ARRANGEMENT? WHY WE NOT INCREASE BFP STAGE WORKING LIKE BOOSTER PUMP?
BFP is costly pump..we can't take risk of cavitation at its suction so function of booster pump is to increase pressure of suction water (more NPSH) and then feed it to BFP for suction
Sir high-pressure turbine or low pressure turbine . Pressure or temperature mein kis range mein Aati hai .( हम कैसे पता करें कि यह स्टीम टरबाइन हाई प्रेशर है या लो प्रेशर है
As we know when steam enters in turbine then steam pressure and temperature decrease in subsequent stage, at exist of HPT pressure is if 28kg/cm2 and temp is 340°C, directly send to boiler for rise in steam temperature, and we also know that boiler works on Isobaric heat addition means pressure remain constant in boiler that's why only temperature increase pressure remain same.
