UNIT 1
INTRODUCTION AND THERMAL POWER PLANT
- A super heat steam rankine cycle has turbine inlet conditions of 2500 psia and 1000F. The turbine and pump polytropic efficiencies are 0.9 and 0.7 respectively. Pressure losses between pump and turbine inlet are 200 psi. Calculate the turbine exhaust steam quality and cycle efficiency.
- An ideal rankine cycle operates with 1000 psia, 1000F steam.It has one closed feedwater heater with drain cascaded backward placed at 100 psia. The condenser pressure is 1 psia. Use TTD = 5F. The heater has a drain cooler resulting in DC= 10F.
- Write short note on:
- Load shedding
- Carbon Credits
