Consider a steam power plant which operates on the simple ideal Bapkos.cycle (shown in the next page), with the following conditions: • The boiler pressure is 3 MEa • The condenser saturation temperature is 50°C • The steam temperature at the exit of the boiler is 500°C • Water leaves the condenser as a saturated liquid • The mass flow rate through each component is 15 kg/s • The isentropic efficiency of the pump and the turbine are 100s and 80%, respectively • Energy is supplied to the boiler by combustion gases that come from a furnace. The gases enter the boiler at 1027'C and leave at 427C. The combustion gases can be treated like "air". • The condenser rejects heat to a river. The river water enters the condenser at 18°C and leaves at 40°C. The specific heat of the river water can be taken as 4.18 kigK

Question
Consider a steam power plant which operates on the simple ideal Baokios cycle (shown in the next
page), with the following conditions:
• The boiler pressure is 3 MPa
• The condenser saturation temperature is 50°C
• The steam temperature at the exit of the boiler is 500°C
• Water leaves the condenser as a saturated liquid
• The mass flow rate through each component is 15 kg/s
• The isentropic efficiency of the pump and the turbine are 100s and 80%, respectively
• Energy is supplied to the boiler by combustion gases that come from a furnace. The gases
enter the boiler at 1027'C and leave at 427C. The combustion gases can be treated like
"air".
• The condenser rejects heat to a river. The river water enters the condenser at 18"Cc and
leaves at 40°C. The specific heat of the river water can be taken as 4.18 k/gK.
Calculate the following:
1. The power output of the steam power plant
2. The thermal efficiency of the steam power plant
3. The mass flow rate of combustion gases from the furnace
4. The mass flow rate of the river water
5. The rate of entropy generation in each of the four components. Explain the differences in
entropy generation rates.
