Presume that coal contains 75% carbon by weight, a combustion heat release rate of 12,000 BTU/lb as well as is burned in a power plant that has a thermal efficiency of 35%. Explain what is the carbon dioxide generation rate, in lb CO2 per MWe-hr and what percentage reduction is needed to meet the U.S. EPA's proposed emission standard of 1,000 lb CO2per MWe-hr? Explain how might the reduction be achieved?
