9 Steam At 6 2 Mpa And 480 C Enters The Turbine Of A Steam Power Plant Operating Under A Regenerative Rankine Cycle Ex 1 (69.79 KiB) Viewed 30 times

9. Steam at 6.2 MPa and 480°C enters the turbine of a steam power plant operating under a regenerative Rankine cycle. Extractions for feedwater heating occur at 3 MPa and 1.4 MPa, with the remaining steam expands to a condenser pressure of 7 kPa. For a steam flow of 55 MTPH from the boiler, determine (a) the mass flow rate of bleed steam, in kg/hr, (b) the turbine power output, in MW, (c) the volume flow rate of cooling water utilized by the condenser, in m³/hr, if the allowable temperature rise of cooling water is 15°C, and (d) the plant heat rate, in kJ/kWh,
