A $400$ MW coal fuelled power plant has an thermal efficiency of $36\%$

and is run with $30\%$ excess air. The heating value of coal is $6600$ kcal$/$kg

and its elemental analysis is provided below. Please determine the flow

rate of the flue gas and pollutant emission rates. Assume that the air has

$1\mathrm{.}1\%$ moisture content. Assume that the plant runs at $80\%$ capacity.
