Compare the thermal efficiency and turbine-exit quality (temperature if superheated) at the condenser pressure for a simple Rankine cycle and the reheat cycle when the boiler pressure is 5 MPa, the boiler exit temperature is 500°C, and the condenser pressure is 20 kPa. The reheat takes place at 0.5 MPa and the steam leaves the reheater at 500°C. (Enthalpies are in KJ/kg.) Without the reheater, the heat added is: The enthalpy entering the condenser is: The net Work is: The enthalpy entering the reheater is: Without the reheater, the net Work is:
An ideal Rankine cycle operates between a steam boiler pressure of 18 MPa and a condenser temperature of 42 °C. The steam leaving the boiler is a saturated vapor. The net power generated by the cycle is 150 MW. What is the mass flow rate of steam? What is the cycle efficiency? Use the formula: n=Wnet/Qin.
A power station consists of a four-unit coal fired power station, having a combined capacity of 2,880 MW. The current efficiency of each unit is around 37.7%. You are asked to improve the thermal efficiency of each unit by lowering the condenser pressure. To simplify this task, assume that each unit operates on a simple ideal Rankine cycle. If the superheated vapour enters the turbine at 10 MPa and 500 ֯C and is cooled in the condenser at a lower pressure 10 kPa, determine the quality of the steam at the turbine exit and the thermal efficiency of the cycle for one unit.
An ideal Rankine cycle with one stage of reheat utilizes steam as working medium. Boiler pressure is 4 MPa, the boiler exit temperature is 400°C, and the condenser pressure is 10 kPa. The reheat takes place at 0.4 MPa and the steam leaves the reheater at 400°C. (Enthalpies are in KJ/kg.). Determine the thermal efficiency of the cycle. Determine also the thermal efficiency if there is no reheater. The quality at the exhaust of the low pressure turbine is: Select one: O a. 13% O b. 97% O c. 3% O d. 87%
