摘要：

The potassium emission characteristics of bagasse and eucalypt bark during their combustion were investigated under different temperature. The influence of different additives on the potassium emission was investigated by the research-scale experiment, pilot scale experiment, and Factsage. The results showed that the potassium emission could be divided into two stages by 600 degrees C. At the high temperature, the degree of difficulty or ease of potassium emission could be estimated by the value of (K+Cl)/(Si+Al). Kaolin and the composite additive, which had the similar reaction mechanism, had a significant effect on the retention of potassium. CaO could reduce the HCl emission during biomass combustion. Simulation results showed that the molten compounds had increased after adding the additives, and potassium existed in the form of KAlSi2O6, which consisted with the practical results.
