Acoal-burning steam power plant produces a net power of 300 mw with an overall thermal efficiency of 33 percent. the actual gravimetric air–fuel ratio in the furnace is calculated to be 12 kg air/kg fuel. the heating value of the coal is 28,000 kj/kg. determine the amount of coal consumed during a 24-hour period. (you must provide an answer before moving to the next part.) the amount of coal consumed is kg/s.
