Question
A regenerative steam turbine has a throttle pressure of 5.3 MPa at 450OC and a condenser at 0.021
MPa. Steam are extracted at the following points: 3.9 MPa, 2.4 MPa and 0.46 MPa. For the ideal cycle, find (a) the thermal efficiency, steam rate SR, and engine heat rate. (b) Estimate the percent
improvement of heat rate from the corresponding Rankine engine. (c) If from actual test the
combined steam rate is 6.5 kg/kW-h and the generator efficiency if 93%, calculate the actual amount
of bled steam per kg of throttle flow using feedwater temperature leaving the last heater at 210OC.
Assume fluid work is equal to brake work.
