Question
A GPP uses a simple Brayton cycle.
Air enters the compressor at pressure, P = 1 bar,
temperature, T = 20°C and exits the compressor at a pressure of 7 bar.
Combustion chamber temperature = 800°C. Compressor efficiency, nk = 0.82, turbine efficiency, nT = 0.85. Turbine power 4 MW. Define:
System installation diagram and cycle process on the P-v and T-s diagram
P-v and T-swK, wt and rl cycles. BWR, mair, Wtnet, mfuel (qfuel : 40,000 kj/kg)
Note : Air, cp,d : 1 ,005 kj/kg.k, k : 1 ,4
1 .15 kl/kg.k, k gas : 1 .3
