Abstract
Ash deposition and corrosion are easily happened in the heating surfaces of biomass boiler. The gaseous of chlorine and potassium released from biomass under combustion is the main reason. Wheat straw, rice straw and other four kinds of biomass were combusted at 5 different temperatures, including 650, 700, 750, 800 and 850℃ in tube furnace, and all flue gas was absorbed, the ion meter and atomic emission spectrometry were used to measure the concentration of chlorine and potassium, respectively, the emission characteristics of potassium and chlorine in biomass were obtained. The results show that when combustion temperature is below 750℃, the emission of chlorine and potassium as gaseous matter can be inhibited effectively.
