Understanding 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 %.

Get a QuoteTypically 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.

Get a Quote2020-2-29·Boiler Efficiency Calculations Efficiency is a very important criterion in Boiler selection and Design. Efficiency figure depends upon the type of boiler as well as on the type of fuel and its constituents. For example, efficiency of a Bagasse fired boiler is about 70% where as that of oil fired boilers is about 85 %.
