Abstract

The effects of desulfurizer CaO with a diameter of 415 Â¿m on N₂O reduction with biomass gasification gas reburning at a reactor temperature of 850Â°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.
