A coal-fired power plant produces a net electrical output of 350 MW. The composition of the coal burned is C = 72%. J = 5%, S = 2%, O = 8%, N = 1% and ash = 12% by weight. The heating value is 40,000 kJ/kg and the plant’s thermal efficiency is 25%. a. How much electricity does this plant generate in one year if the plant runs at full capacity? b. How much coal (metric tons) does this plant consume in one year running at full capacity? c. If the plant’s annual capacity factor is 0.63, how much coal (metric tons) is consumed?

Question
A coal-fired power plant produces a net electrical output of 350 MW. The composition of the coal burned is C = 72%. J = 5%, S = 2%, O = 8%, N = 1% and ash = 12% by weight. The heating value is 40,000 kJ/kg and the plant’s thermal efficiency is 25%.
a. How much electricity does this plant generate in one year if the plant runs at full capacity?
b. How much coal (metric tons) does this plant consume in one year running at full capacity?
c. If the plant’s annual capacity factor is 0.63, how much coal (metric tons) is consumed?
d. How many metric tons of CO2 are emitted in one year at full capacity and with a capacity factor of 0.63?
