Schematic of the
Cogeneration Power Plant
Due to the rapid rise in fuel prices, and the potentially
energy efficient of district heating (DH) system,
the use of district heat is on the rise in many countries. A new community, that is under construction in
Oklahoma is considering this system. A cogeneration vapor
power plant in this community is used to provide the district heating as well as
generate the electricity for the community.
What is known:
- Steam enters the turbine at 16 MPa and 600oC
- Steam is extracted from the turbine at 5 MPa and sent to heat exchangers.
Steam leaves the heat exchanger as saturated water, and the heat
exchanger has an efficiency of 85%.
- The total district heating requirement is 1,100 kW in winter.
- The electricity requirement from this power plant is 5,500 kW in winter.
