AbstractBiomass is a form of energy that is CO(2)-neutral. However, NO(x), emissions in biomass combustion are often more than that of coal on equal heating-value basis. In this study, a technology called decoupling combustion was investigated to demonstrate how it reduces NO emissions in biomass and biomass-coal blend combustion. The decoupling combustion refers to a two-step combustion method, in which fuel pyrolysis and the burning of char and pyrolysis gas are separated and the gas burns out during its passage through the burning-char bed. Tests in a quartz dual-bed reactor demonstrated that, in decoupling combustion, NO emissions from biomass and biomass-coal blends were both less than those in traditional combustion and that NO emission from combustion of blends of biomass and coal decreased with increasing biomass percentage in the blend. Co-firing rice husk and coal in a 10 kW stove manufactured according to the decoupling combustion technology further confirmed that the decoupling combustion technology allows for truly low NO emission as well as high efficiency for burning biomass and biomass-coal blends, even in small-scale stoves and boilers.
