Cofiring high ratios of biomass with coal

biomass by weight or 10% by energy output. Cofiring can be direct, where the biomass and the coal are fired in the same boiler or indirect, where the combustion or gasification of the biomass occurs in a separate unit. Direct cofiring is the simplest and most widely applied technology for cofiring biomass.

Biomass Combustion - Ontario

Biomass combustion is clearly a proven technology, but design improvements over the past couple of decades have helped to increase its efficiency, reduce emission levels and reduce costs. At the same time, the creation of professional certification programs for installers and inspectors has helped to boost the safety of biomass combustion systems.

Biomass Combustion - FSA1056

Since biomass fuels are primarily composed of carbon, hydrogen and oxygen, the main products from burning biomass are carbon dioxide and water. Flame temperatures can exceed 2000°C, depending on the heating value and moisture content of the fuel, the amount of air used to burn the fuel and the construction of

Optimal Combustion Process - Fuels and Excess Air

Even so-called "on-ratio" combustion, used in boilers and high temperature process furnaces incorporates a modest amount of excess air - 10 to 20% more than needed to burn the fuel completely. If insufficient amount of air is supplied to the burner, unburned fuel, soot, smoke, and carbon monoxide are exhausted from the boiler.

Characteristics of Biomass as a Heating Fuel

Biomass can be a source of liquid fuel (e.g., biodiesel) or gaseous fuel (e.g., "wood gas"), but the most common use is as a solid fuel (e.g., wood, biomass pellets). This fact sheet presents some of the more important characteristics of solid biomass fuel and explains their significance.
