WebOct 7, 2024 · A commercial boiler requires an input of 300,000 Btu/hour or greater. A residential boiler requires an input of less than 300,000 Btu/hour. Energy is lost in the process of the boiler transferring heat to the water. This energy loss dictates the efficiency of a boiler. Boiler efficiency can be defined in a few ways. WebH = fuel heat input rate, [106 Btu/min], at the HHV, measured at engine fuel feed line, usually as feed rate calculated as (fuel feed rate in ft3/min)(fuel heat content in 106 Btu/ft3) O 2 = stack oxygen concentration, dry basis [%] Alternatively, a source may want to measure dry CO 2 and use the carbon dioxide based F factor, dry basis.
