A coal-fired power plant produces a net electrical output of 500 MW. The composition of the coal burned is C= 72 %, H= 6 %, S= 3.5 %, O= 6 %, N= 1 %, and ash= 12 % by weight. It's heating value (HV) is 30200 kJ/kg. The net thermal efficiency is 36%. The annual capacity factor is 70 %.
a)How many metric tons/day of SO2 are emitted if 97% of the sulfur in coal is converted to SO2?
b) How many metric tons/day of NOx are emitted if the NOx emission rate is 265.0 ng/J?
