A lignite-fired power plant was designed to produce electricity at a maximum capacity of 750 MW. By average over a year, the plant is operated at 35% plant efficiency and 65% of the design capacity. Assume that the entire amount of sulfur in lignite coal entering the plant is converted to sulfur dioxide (SO2). The power plant is equipped with an 85% efficiency SO2 removal unit. Use the engineering calculation approach and the coal information (dry basis) found in your lecture notes to determine emission rate of SO2 in lb/hr and in lb/BTU input.
