秸秆类生物质燃烧结渣与沉积倾向分析

生物质能是清洁的能源,开发生物质能源对我国有深远的社会意义和广阔的市场前景.但是生物质燃料固有的高碱金属含量的特点,成为阻碍生物质燃料广泛利用的主要因素.介绍了生物质燃料特性和燃烧特性,并结合对生物质在层燃炉排炉和循环流化床燃烧方式的分析,指出其在燃烧过程中可能产生的结渣和沉积倾向,并提出了相应的对策.;As a clean energy,biomass energy used in China has a profound social significance and broad market prospect.The biomass fuels inherently has high content of alkali,which causes the main obstacle to the wide use of the energy.The biomass fuel properties and the combustion characteristic are introduced.Combined with the analysis of combustion in biomass burning grate furnace and circulating fluidized bed,the possible tendency of biomass burning slags and deposits are discussed,and some countermeasures are given
