Bottom and fly ash handling systems

Effectively handling high-temperature boiler ash

Cost-effective production of energy biomass is very much dependent on efficient handling of available biomass sources, as well as the efficiency of each process. Combusting biomass in a boiler generates ash with high temperatures. This ash (either bottom or fly ash) needs to be cooled and/or processed to a form that can be transported from the power plant.
