The steam consumption of a steam power plant is 40 tonnes per shift of 8 hours when developing 300 kW power.
Saturated steam enters the turbine at 16 bar and leaves at 0.2 bar. The properties of steam are given below.
At 16 bar ,
hg=2976.2 kJ/kg
Sg=6.282 kJ/kgK
At 0.2 bar ,
hf=180.1 kJ/kg
sf=0.612 kJ/kgK
The steam at outlet of turbine has 11% moisture in it. Neglect pump work thermal efficiency of the plant is
