Abstract :
The effects of desulfurizer CaO with a diameter of 415 ¿m on N2O reduction with biomass gasification gas reburning at a reactor temperature of 850°C was researched on a small-scale fluidized bed in this paper, and the main mechanisms of the effects caused by the desulfurizer CaO were analyzed. The results of the experiment showed that the N2O decomposition rate was improved by ejecting biomass gasification gas reburning and arranging the bed material CaO on the distributor; the NO formation rate was enhanced with biomass gasification gas reburn and was decreased with the effect of desulfurizer CaO.
