Consider an ideal steam regenerative cycle in which steam enters the turbine at 3.0 MPa, 400°C, and exhausts to the condenser at 10 kPa. Steam is extracted from the turbine at 0.8 MPa to an open feedwater heater. The feed water leaves the heater as saturated liquid. The appropriate pumps are used for 2 the water leaving the condenser and the feed-water heater. Calculate (a) the thermal efficiency of the cycle, (b) the net work per kilogram of steam, and (c) the rate of exergy loss in the feed-water heater.

In a regenerative ideal Rankine cycle, hot water steam enters the turbine at 10 MPa and 480°C. condenser inlet pressure is 10 kPa. Some steam is taken from the turbine at a pressure of 0.7 MPa, feeds a Closed Feed water heater and is sent to the condenser as a saturated liquid at a pressure of 0.7 MPa at the outlet. The other outlet (cold) is at a pressure of 10 MPa and a saturation temperature of 0.7 MPa. According...

a) A steam power plant operates on an ideal reheat-regenerative Rankine cycle. Steam enters the high-pressure turbine (HPT) at a pressure of 10 MPa and temperature of 550°C. The steam expands through the HPT stage to a pressure of 0.6 MPa. Some of the steam at the end of the expansion process in HPT is extracted for a regeneration process in a closed-type feedwater heater. The steam leaves the heater as a saturated liquid and then is throttled to the...

Water is the working fluid in an ideal regenerative Rankine cycle with one closed feedwater heater. Superheated vapor enters the turbine at 12 MPa, 480°C, and the condenser pressure is 6 kPa. Steam expands through the first-stage turbine where some is extracted and diverted to a closed feedwater heater at 0.7 MPa. Condensate drains from the feedwater heater as saturated liquid at 0.7 MPa and is trapped into the condenser. The feedwater leaves the heater at 10 MPa and a...
