A coal with the following composition is burned at a rate of 15000 kg per hour in a power plant. The excess air used was 20%. Carbon - 66.10%, Hydrogen- 6.03%, Oxygen -11.91%, Nitrogen-1.04%, Sulfur-2.40% and Ash-12.52%. Assuming a 100% conversion of the fuel and no nitrogen oxides form and all sulfur converts to SO2, calculate the flue gas composition. The flue gases produced are cooled from 1000 C at the outlet of the furnace to 600 C in a superheater. Saturated steam at 80 bar enters the superheater and leaves with a 100 C superheat. What quantity of superheated steam is generated in the boiler?
