Question

Problem 3: Remember efficiency is power out/energy in for power plants. For Scrubbers or other air pollution controls, efficiency refers to the percentage of “mass of pollutant removed"/*mass of pollutant

going in". Coal can have different energy intensities and is rated in terms of the BTUS of heat it releases per lb of coal.Consider a new 38 percent efficient 600-MW power plant burning 9,000 BTU/lb coal containing1 percent sulfur (by mass). If a 70 percent efficient scrubber is used, what would be the emission rate of sulfur be (lb/hr)?
