Power Plant Equipment

A gas turbine plant of 800 kW takes air at 100 kPa and 288 K with flow rate 6 kg/s. Pressure ratio=6, maximum temperature=900 K, regenerator effectiveness=80%, isentropic efficiencies of compressor and turbine=85%. Determine plant thermal efficiency and net power. Take Cp=1.005 kJ/kg·K and γ=1.4.

Explain how regenerator/regeneration increases the output of the gas turbine power plant along with the neat sketch and show the cycle in P-V and T-S diagram.

List the common method(s) used for the performance improvement of the steam turbine power plant(s). Explain how reheating increases efficiency of the plant.

Explain how reheater/reheating increases the output of the steam turbine power plant along with neat sketch. Draw the layout and show the cycle in T-S diagram.
