  • Boiler Efficiency - an overview | ScienceDirect Topics

    Typical boiler efficiencies range from about 90% for the best solid biomass fuel boilers to close to 95% for oil- and natural gas-fired boilers, Table 3.2. The main reason for the poorer performance of biofuels is the high moisture content of the fuel, which increases flue gas losses.Get Price
