Numerical modeling of biomass combustion in a stoker boiler

Biomass fuel is considered a promising substitute for traditional fossil fuels. Amid a great variety of methods for converting the energy in biomass fuel into usable energy, direct combustion is still the dominant technology employed by industry. Because biomass fuel possess a much wider range of physical and chemical properties than fossil fuel, its combustion behavior is similarly diverse

Biomass Cofiring in Coal-Fired Boilers

Biomass cofiring projects do not reduce a boiler's total energy input requirement. In fact, in a properly implemented cofiring application, the efficiency of the boiler will be the same as it was in the coal-only operation. However, cofiring projects do replace a portion of the non-renewable fuel—coal—with a renewable fuel—biomass.
