The MBHE BioBurn Combustion Chamber (BCC) furnace design, used for spreader firing on BioBurn grates or CAD grates, makes use of proven design concepts for firing biomass fuels.
Commonly, biofuels such as vegetable refuse or bagasse have high moisture content and are difficult to burn, particularly in the case of waste wood or bark. MBHE furnaces are designed to have ‘hot zones’.
Strategically located arches in the MBHE BCC furnace provide clearly defined combustion zones and allow introduction of over-fire air nozzles to ensure turbulent mixing of air and combustibles in a defined chamber. In addition, the combustion resident time in the lower zone is improved, giving a higher combustion efficiency compared with straight vertical furnace designs.
