Question

For ideal cycle and engine, calculate a) the thermal efficiency, b) the engine steam rate, c) actual condition of the exhaust steam, and d) steam flow rate in kg/h for 1.1 MW generator output at 94% efficiency

1. A Rankine turbo-generator unit receives 27,800 kg/hr of steam at 1.2 MPa and
superheats by 122 degrees. Condensate leaves at 22°C. For a brake steam rate 4.74
kg/kWh, mechanical efficiency of 90% and generator efficiency of 94%, Determine the:
a) Ideal cycle thermal efficiency
b) Indicated engine efficiency
c) The condition of turbine actual exhaust
d) The turbo-generator outputs in kW.
