| 英文摘要 | Biomass is an abundant and clean resource with good application value. However, due to high contain of alkali metals, it causes boiler's corrosion and slagging during utilization. In this paper, pyrolysis experiments were carried out from 200 to 1000 degrees C and a series of detection methods are applied to explore occurrence, release and conversion characteristics of wheat straw. When temperatures are raised from 200 to 1000 degrees C, water-soluble K releases first. Then NH4Ac soluble K converts to water-soluble K. It is found that NON content is high, which accounts for 27.11% of total anions. At low temperatures (<400 degrees C) 35.50% K will release as KNO3, which is larger than that of the solid fuels with less NO3-. Meanwhile part of K and Cl enriches on particles surface due to carrying of moisture. When temperatures are higher than 400 degrees C, K is mainly released in the form of KCl. As KCl on the sample surface is released, K and Cl inside the sample can't reach the sample surface. At 600 degrees C, the total KCl content increases to the maximum. Furthermore it is found that NH4Ac soluble K can convert into water-soluble K. When it is 800 degrees C, K release is 53.66%. And K release accounts for 55.26% at 1000 degrees C.
