the water produced by the combustion of H 2 is = mol O 2. We know that 1 K mole of H 2 combines with ½ K mol O 2 to produce water. Therefore the amount of hydrogen present is = mol/100K mol of dry flue gases, and the carbon present is = /100K mol of dry flue gas.
The amount of heat contributed by the combustion of sulfur in coal is relatively small, because the heating value of sulfur is only about 4,000 Btu per pound, and the sulfur content of coal generally averages 1 to 2 percent by weight.
Firstly, find the water flow through the boiler in pounds per hour (lbs/hr). Multiply the water flow rate (in gallons per minute, gpm) by 60 (minutes per hour) and then by the weight of water per gallon ( lbs/gal). For example, if the flow rate is 800 gpm, the water flow through the boiler would be:
