Biomass boilers run at an efficiency of 89 – 91% (Trianco Greenflame – 91%; Angus Orlingo 500 – 92%), while the top-rated gas boilers similarly run between 88 – 91% efficiency (Baxi Duo-tec HEA 91%; Valiant Ecotec Plus series over 91%); therefore biomass boilers are comparable to conventional gas boilers.
Improve Your Boiler’s Combustion Efficiency Combustion Efficiency Operating your boiler with an optimum amount of excess air will minimize heat loss up the stack and improve combustion efficiency. Combustion efficiency is a measure of how effectively the heat content of a fuel is transferred into usable heat.
An alternative to achieving efficiency improvements in conventional pulverised coal-fired power stations is through the use of gasification technology. IGCC plants use a gasifier to convert coal (or other carbon-based materials) to syngas, which drives a combined cycle turbine. More information can be found on the gasification section.
