Combustion of different types of biomass in CFB boilers

Fluidized Bed Combustors for Biomass Boilers

Fluidized-bed boilers are the most common type of boilers recommended for biomass fuel. The fuel is suspended by an upward flow of combustion air through a bed of hot, inert particles, allowing oxygen to reach the combustible material more readily.

Coal and peat ashes are usually trouble free at these temperatures, even if the melting point temperatures are in the same range with biomass fuels. Coal or peat is cofired with biomass in many multifuel fired boilers. The woody biomass ashes are in general much more reactive than the ashes of fossil fuels.

The primary advantage of CFB gasification technology is that it enables the substitution of expensive fuels e.g. oil or gas with cheap solid fuels. These cheap fuels are typically different types of waste woods, bark or other biofuels. The process may also solve a waste disposal problem, providing a secondary economic and environmental benefit.
