A reheat-regenerative rankine cycle needs to produce 150MW of net power. Boiler pressure is at 15MPa. Reheat occurs at 10MPa. extractions occur at 5MPa and 2MPa for open feedwater heaters. These extractions occur after the expansion after reheating. Steam leaves the boiler and reheater at 600C. Condenser pressure is at 10kPa. SOLVE FOR: a.) Determine the amount of steam needed passing through the boiler to produce the required net power (kg/s) b.) Determine the amount of heat added to the system (kJ/s) c.) Determine the thermal efficiency of this cycle (%)

Question

A reheat-regenerative rankine cycle needs to produce 150MW of net power. Boiler pressure is at 15MPa. Reheat occurs at 10MPa. extractions occur at 5MPa and 2MPa for open feedwater heaters. These extractions occur after the expansion after reheating. Steam leaves the boiler and reheater at 600C. Condenser pressure is at 10kPa.

SOLVE FOR:

a.) Determine the amount of steam needed passing through the boiler to produce the required net power (kg/s)

b.) Determine the amount of heat added to the system (kJ/s)

c.) Determine the thermal efficiency of this cycle (%)
