A parametric investigation on pulverized biomass combustion

The compromise to reduce CO{sub 2} emissions in the near future will be possible only if the use of fossil fuels is substantially reduced. Pulverized biomass combustion is an interesting option due to the relative facility in which the actual combustors may be adapted to burn such feedstock. However, the knowledge of the biomass particle's behavior in pulverized flames is lacking of more detailed study. This paper intends to clarify many processes that take place in the boundary layer of a single biomass particle burning in different conditions. The parametric study, thus presents the influence of particle size, oxygen content and gas temperature of the bulk as well as of some physical properties on the reactivity and fuel NO conversion in the combustion of biomass.
