Typically for a natural gas boiler oxygen readings may be in the range 3% to 5%, for an oil boiler 5% to 8% and for a coal fired boiler 8% to 10%. The combustion efficiency of modern condensing gas boiler can theoretically be over 100% as heat is extracted from the incoming air. A traditional brick built coal fired boiler may only be 50% efficient.

Learn More2018-8-5·Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings. The

Learn MoreUnderstanding Indirect Boiler Efficiency. Indirect Efficiency Calculation & BS845. The method most standards (including IS8753, BS845 etc.) follow is the indirect efficiency calculation method. In this method, each loss is individually calculated, and the sum of these losses is then subtracted from 100 to give efficiency %.

Learn MoreBoiler efficiency is depended on the proper combustion of fuel, effectiveness of Heat transfer, operation and maintenance. Thermal efficiency of boiler is defined as the percentage of heat input that is effectively utilised to generate steam.
