A steam power plant is based on the Rankine cycle with reheat (refer to the figure below). Steam is produced by the boiler/superheater (H-1) at 100 bar and 600 C at a rate of 2.5 kgs. This is expanded to 10 bar in the turbine T-1 and then reheated to 600 °C in heater H-2. The steam is then expanded in turbine T-2 to a pressure of 0.1 bar. The steam is then condensed in condenser (C-1) which operates at...

Example: Consider a steam power plant operating on the ideal reheat Rankine cycle. Steam enters the high-pressure turbine at 15 MPa and 600 °C and is condensed in the condenser at a pressure of 10 kPa. If the moisture content of the steam at the exit of the low-pressure turbine is not to exceed 10.4 percent, determine (a) the pressure at which the steam should be reheated and (b) the thermal efficiency of the cycle. Assume the steam is reheated...

Thermodynamics II Assignment 5 Instructor: Mohd AWAD 999999REPPI A steam power plant operates on an ideal reheat-regenerative Rankine cycle and has a net power output of 80 MW. Steam enters the high-pressure turbine at 10 MPa and 550°C and leaves at 0.8 MPa. Some steam is extracted at this pressure to heat the feedwater in an open feedwater heater. The rest of the steam is reheated to 500°C and is expanded in the low-pressure turbine to the condenser pressure...

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...
Steam power plant using the reheat Rankine cycle
A steam power plant operates using the reheat Rankine cycle. Steam enters the high pressure turbine at 12.5 MPa and 550ºC at a rate of 7.7 kg/s and leaves at 2MPa. Steam is then reheated at a constant pressure to 450ºC before it expands in the low pressure turbine. The isentropic efficiencies of the turbine and the pumpare 85% and 90%, respectively. Steam leaves the condenser as a saturated liquid. If the moisture content of the steam at the exit...
