A 825 MW electric power plant (36.2 % efficient) uses a coal with the following composition (C = 74.8 wt%, H = 5.2 wt %, O = 7.3 wt%, N = 0.4 wt%, and ash = 12.3 wt %, with energy content 9,950 BTU/lb). Combustion occurs with 50% excess air to form CO2, H2O, and NO. Assume 35% of fuel nitrogen converts to NO, and that fuel NO is 80% of total NO (the remainder being thermal NO). Calculate a) the NO concentration (ppm) in the exhaust gas and b) the daily production of NO.
