How to calculate industrial boiler coal consumption? Take a steam boiler for example, its coal consumption is related to the operating load: coal consumption (kg) = steam (ton) x The steam enthalpy (kcal / kg) X1000 /[coal calorific value (kcal / kg) x boiler thermal efficiency].

Read MoreHere is the equation to calculate an unloaded steam cost: = Steam cost, unloaded = Fuel cost in $/MMBtu = Enthalpy of steam, in Btu/lb. = Enthalpy of boiler feedwater in Btu/lb. = True boiler efficiency (ASME PTC 4.1) o Percentage = Steam cost is measured in 1,000 lbs. per hour.
