摘　　要：对玉米芯、糠醛渣及其燃烧后炉渣进行了全硫和形态硫分析,并根据水解反应原理得出结论:催化剂硫酸在水解反应后仍以硫酸形态存在于糠醛渣中,糠醛渣在锅炉中燃烧后,质量分数为97.4%的硫酸以SO3形态析出,并在高温环境下很快裂解为SO2,剩余的硫酸主要以硫酸盐形态存在于炉渣中。The total sulfur and forms of sulfur in corncob,furfural residual fired and slag were analyzed in this paper.The result based on the hydrolyze principle shows that sulphur exist as the sulfuric acid form in furfural residue.When furfural residue burns in the boiler,sulfuric acid（97.4%,m/m） in furfural residue is salted out as SO3 form,and SO3 is soon pyrolyzed to SO2 under the condition of high temperature,and the rest sulfuric acid exists as sulphate form in slag.
