How to Calculate Boiler Steam Flows Hunker

Calculate the combustionair mass required to burn the 20 gallons of No. 6 fuel oil above. Since the airfuel stoichiometric ratio is 14.4 pounds of air per pound of fuel, the boiler's burner would need 20 gallons x 7.95 lb/gal for No. 6 fuel oil, or 2,289 pounds of air to burn the oil. This would in turn yield a total flow of 2,628.1 lb/hr of

Energy Management in Small and Medium sized Rerolling

Pulverized coal is pneumatically conveyed to the reheating furnace. An air blower is normally used for the blowing of air which is used for the pneumatic transport of the coal. This blower also needs energy (electric energy). The amount of energy required is dependent upon the quantity and the pressure of air to be blown. Coal contains moisture.
