A coal-burning power plant produces 1500 MW of power with an efficiency of 0.3. Giventhat 20% of the waste heat is released to the air via the stack gases, at what rate do theyneed to withdraw water from the ocean to discharge the remaining waste heat if theyare limited to a 5ᵒC increase in water temperature?Answer: 133.8 m3/sb) Recognizing that this is an excessive volume of plankton-rich water, new regulationsfocus on the withdrawal rate and limit it to 1000 MGD (million gallons per day). Whatwould be the temperature increase of the thermal discharge in this case?Answer: 15.28ᵒCc) If both regulations are applied, the power company will have to reduce powerproduction to continue operating. Assuming they continue to discharge 80% of theirwaste heat through cooling waters, how much electric power could they produce withtemperature increase limited to 5ᵒC and withdrawal rate limited to 1000 MGD?Answer: 491 MW
A coal-burning power plant produces 1500 MW of power with an efficiency of 0.3. Given
that 20% of the waste heat is released to the air via the stack gases, at what rate do they
need to withdraw water from the ocean to discharge the remaining waste heat if they
are limited to a 5ᵒC increase in water temperature?
Answer: 133.8 m3/s
b) Recognizing that this is an excessive volume of plankton-rich water, new regulations
focus on the withdrawal rate and limit it to 1000 MGD (million gallons per day). What
would be the temperature increase of the thermal discharge in this case?
Answer: 15.28ᵒC
c) If both regulations are applied, the power company will have to reduce power
production to continue operating. Assuming they continue to discharge 80% of their
waste heat through cooling waters, how much electric power could they produce with
temperature increase limited to 5ᵒC and withdrawal rate limited to 1000 MGD?
Answer: 491 MW
