combustion. In pulverized coal systems, combustion is almost complete; thus, the emitted PM is primarily composed of inorganic ash residues. Coal ash may either settle out in the boiler (bottom ash) or entrained in the flue gas (fly ash). The distribution of ash between the bottom ash and fly ash fractions directly affects the PM emission rate

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:
