Abstract

  Our previous studies have reported on the combustion characteristics of sewage sludge in a fluidized bed incinerator with a turbocharger which can achieve not only energy recovery but also a low environmental impact. The objective of this study is to elucidate the co-firing characteristics of the sewage sludge and biomass in a demonstration plant. The tested biomass is wood tip, bark, grass and pasture. As a result, the temperature of the sand bed in co-firing condition is considerably higher than that in the sludge only combustion because the residual char of biomass after pyrolysis burns stably in the sand bed for the co-firing. Additionally, N2O emission can be controlled by the freeboard temperature in all experimental conditions. Therefore, our results indicate that the combustor can reduce the environmental impact of N2O emission in co-firing conditions.
