芒荻类植物的燃烧特性及动力学分析
Combustion characteristics and kinetic analysis of Miscanthus and Triarrhena
摘要
Abstract
The combustion characteristic of Chinese silvergrass,Miscanthus floridulus,Amur silvergrass and Triarrhena lutarioriparia were investigated by the TG-DTG thermal analysis technology.The activation energy,frequency factor and correlation coefficient were analyzed by the Coats-Redfern method.The results demonstrate that there are three stages during the combustion of Miscanthus & Triarrhena:dehydration,release and combustion of volatile,combustion of coke.From high to low,the comprehensive combustion performances of the four plants are Triarrhena lutarioriparia,Chinese silvergrass,Amur silvergrass,Miscanthus floridulus,and all of them are better than corn straw.The dynamic analysis of the combustion reactions shows that the activation energy of the volatile release and combustion is less than 40 kJ/mol,while the coke combustion is difficult and its activation energy is up to 147 kJ/mol.关键词
