An oil fired power station burns 2 800MW oil. 340 MW is lost as heat in the smokestack and an extra 1 030 MW is lost due to efficiency losses in the turbine as waste heat. A nearby river (flow rate 100 m³/ s) is used to supply coolant water. • How much is the river temperature raised by? • What is an acceptable rise in water temperature? • What are the environmental impacts of this temperature rise? What alternatives are there? ● An oil fired power station burns 2 800MW oil. 340 MW is lost as heat in the smokestack and an extra 1 030 MW is lost due to efficiency losses in the turbine as waste heat.

Expert Answer:
Answer rating: 100% (QA)
To calculate the temperature rise of the river water we can use the formula for heat transfer Q m Cp T where Q is the heat transferred m is the mass flow rate of water density flow rate Cp is the spec... View the full answer
