Abstract

The Si–Al additives shared positive effects on relieving the severe problems of slagging, fouling, and depositions by destructing the alkali sulfates and chlorides during biomass combustion. In the present study, the decomposition of sulfates in the biomass ash was studied by using XRD, XRF, and TG-DSC. Results showed that sulfates in the biomass ashes began to decompose over 1000 °C and almost completely at 1100 °C. The aluminum–silicon additives promoted the decomposition of sulfates, but the Kaolin addition showed a stronger promotion effect. It was further proved by the further analysis of thermo-equilibrium calculation and TG-DSC on the biomass ash and potassium sulfate.
