Q2. A cogeneration steam power plant has been modified with introducing an open feedwater heater as shown in figure below. Working pressure of the plant is between 6 MPa and 10 kPa for the boiler pressure and condensate pressure. The steam is extracted at 0.5 MPa for process heater and feedwater heater. The superheated srteam enters the turbine at 500°C at a rate of 25 kg/s and expands to the condensate pressure of 0.5 MPa. There is 60 percent of the steam is extracted from the turbine at the pressure of 0.5 MPa, and the remainder expands to a pressure of 10 kPa. Part of the extracted steam is used to heat feedwater and the rest of the extracted steam is used for process heating. The steam leaves the process heater as a saturated liquid at 0.5 MPa. It is subsequently mixed with the feedwater leaving the feedwater heater, and the mixture is pumped to the boiler pressure. The steam in the condenser is cooled and condensed by the cooling water from a nearby river, which enters the…

1) In an ideal regenerative Rankine cycle, vapor enters the turbine at 7MPa and 550°C. Steam first expands to 0.8MPa where some of the steam is extracted and transferred to an open feedwater heater (FWH) operating at 0.8MPa. The remaining steam expands through the second-stage turbine to the condenser pressure of 10kPa. Saturated liquid exits the open FWH at 0.8MPa and water enters pump I as a saturated liquid. Determine a) the power output of the cycle in kJ/kg b) the thermal efficiency of the cycle c) the heat transfer from the condenser to the environment, in kJ/kg.

A simple ideal Rankine cycle with water as the working fluid operates between the pressure limits of 3 MPa in the boiler and 30 kPa in the condenser. If the quality at the exit of the turbine cannot be less than 80 percent, what is the maximum thermal efficiency this cycle can have? Use steam tables. The maximum thermal efficiency is %.
Scenario (1) The first steam power plant operates on an ideal reheat Rankine cycle. Steam enters the first turbine at 8 MPa and 500 C and leaves at 3 MPa. Steam is then reheated at a constant pressure to 500 C before it expands to 20 kPa in the low-pressure turbine. Assuming that heat is being added to the boiler from a high temperature source at 1800 K and the condenser is transferring heat to a temperature sink at 300 K. Task 1 Investigate the effect of changing pump efficiency on the overall thermal efficiency of the thermodynamics cycle (Hint: You will assume different values for the isentropic pump efficiency such as: 70%, 80%, 90%, 95%, and 100%, then observe how it will change the thermal efficiency of the cycle). Representing the results in a plot is recommended.
