Steam enters the turbine at 10 MN/m' and 450°c. The steam expanded isentropically in the turbine down to the condenser pressure of 20 kN/m'. The power developed by the plant is 5600 kw. The condensate leaving the condenser is pumped to the boiler pressure isentropically. Taking into account the pump work and calculate: • The mass of steam generated in the boiler. • ycle thermal efficiency. • Specific steam consumption. Draw the cycle on a T-s diagram.

HMW-7: Steam Turbine Power Cycles
Steam enters the turbine at 10 MN/m and 450°C. The steam expanded
isentropically in the turbine down to the condenser pressure of 20 kN/m?. The
power developed by the plant is 5600 kW. The condensate leaving the condenser is
pumped to the boiler pressure isentropically. Taking into account the pump work
and calculate:
• The mass of steam generated in the boiler.
• Cycle thermal efficiency.
• Specific steam consumption.
Draw the cycle on a T-s diagram.
Hint: 1 MN/m² = 10 bar
