  • AP-42 Section 1.6 Wood Residue Combustion in Boilers

    of combustible carbonaceous fly ash. Steps can be taken to reduce this hazard, including the installation of a mechanical collector upstream of the fabric filter to remove large burning particles of fly ash (i. e., "sparklers"). Despite complications, fabric filters are generally preferred for boilers firing salt-laden wood.Learn More

  • Ash Management Review—Applications of Biomass Bottom Ash

    In addition, high levels of unburned carbon can be found in the ash produced from boilers. According to Demirbas, the fly ash from biomass-fired grate boilers contain high levels of unburnt carbon and is not suitable for recycling to the forest. Grate boilers often produce a fly ash with 50% or more of unburnt carbon.Learn More

  • Fly Ash Collector

    Most factories are equipped with biomass fired boilers using coal, rice husk, bagasse, etc. Huge quantity of burnt biomass and partially unburnt Fly Ash is generated in boilers which escapes in the flue gases into the air. The quantity of the flue gas emission has to comply with the norms of the Pollution Control Boards.Learn More
