1) A coal-burning steam power plant produces a net power of 300MW with an overall thermal efficiency of 32 percent. The actual gravimetric air-fuel ratio in the furnace is calculated to be 12kg air /kg fuel. The heating value of the coal is 28,000kJ/kg. Determine (a) the amount of coal consumed during a 24-hour period and (b) the rate of air flowing through the furnace
