Biomass is a viable source of renewable energy that can reduce energy consumption and greenhouse gas and other emissions in coal-fired boilers. As environmental sustainability increases in coal-fueled energy generation, more plants are implementing solutions to meet mandated or enforceable renewable portfolio standards (RPS).
Woody biomass has been and continues to be the major source of feedstock for pellet production. The steam explosion process may expand the resource base to other biomass residues, such as agricultural residues. Agricultural residues typically contain high ash and alkali metals, as well as high chlorine which present challenges in boiler operations.
The causes of biomass fires are numerous. All you need is fuel, oxygen and a source of ignition. For a dust explosion / deflagration to occur, two additional factors are required: mixing the explosive dust with air in the necessary concentration and confining the mixture in a container or structure.
