Project Description: WSU is considering a co$-$generation steam turbine power plant for its electricity and

hot water needs. During the weekdays, the maximum demand for electricity is estimated at $50$ MW $.$ The

overall system should $($at least$)$ contain the following components: a boiler, $2$ or $3$ turbines, an open

feed water heater, a close feed water heater, $2$ or $3$ pumps, and a condenser$/$process heater for

transferring heat to the cold water. Feel free to add other components as necessary

Design Constraints:

$($a$)$ Efficiency of the thermal system should be higher than $45\%$

$($b$)$ Boiler pressure should be less than $25$ MPa

$($c$)$ Combustion efficiency $90\%$

$($d$)$ All pumping energy should come from the turbine work

$($e$)$ City water enters the condenser at $10C,$ and leaves the condenser at $40C$

Additional Considerations:

The power plant is turned off between $1$ AM and $6$ AM $.$ Turbines' isentropic efficiency is $90\%,$ while the

pumping process is nearly isentropic$.$

Deliverables for the Preliminary Report

$($a$)$ Design a co$-$generation plant for this purpose. Draw the system $($block$)$ and T$-$s diagram of the

system. Label each term in the block diagram. List all assumptions used in this project.
