1 Air Emissions and Controls Lecture 25 Emission Calculations ICP#21, 22 Emission Controls and NSPS Emission Controls Devices ICP#23 Alternate Electricity Energy Sources Reading: R: Ch. 5 section 5.5.1 (pg. 196- 206) and sections 5.6-5.9 (pg. 210-228) Resource Utilization/Emissions in Coal Power Plant A 500 MW power plant burns bituminous coal. The overall plant efficiency is 36% and operates at an annual capacity factor of 65% (due to maintenance and demand fluctuation). 2.8 mil. MW*hr/yr (~0.001 of total electricity from US coal) 1 billion kg coal / year 98 million kg ash / year 15 million kg sulfur / year 2.4 billion kg CO 2 / year Electricity Energy and Mass Flow in elec E E = η E in = E waste + E elec coal in coal HV E m = Pollution controls are about 40% of power plant cost today. They consume 5% of the energy produced, lowering efficiency. \$200M Coal Fired Power Plant Emission Factors (uncontrolled) CO 2 Emissions from Coal vs. Natural Gas Combustion ICP# 21: Calculate the CO 2 emissions from bituminous coal and natural gas combustion on the basis of emissions per unit energy released. Assume coal contains 67% C by weight with an energy content of 28.4 MJ/kg, while natural gas contains 74% C by weight and releases 54.4 MJ/kg.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
