| 摘 要： | 为解决生物质与煤混燃存在的结渣积灰问题.以稻秸秆、白杨木屑、稻壳和煤在不同配比下混合燃烧的灰分作为研究对象,利用HR-3C灰熔融性测定仪研究了生物质与煤混合燃烧的熔融特性.研究表明:生物质燃料中碱金属含量比煤中的含量要高,提高生物质的掺入比总体上会使灰熔融温度降低;此外,对于二氧化硅含量不同的生物质燃料其灰熔融性有所差...

| Abstract: | To solve the problems of slagging and fouling during co-firing of coal and biomass.The ash character of coal and 3 sorts of biomass(rice stem,poplar sawdust,rice husk) blends in different mixing proportions were studied by the HR-3C detector of ash fusion.The results show that: the alkali metal content in biomass fuels is higher than the coal content;the biomasses fraction is raised,the ash fusing temperature of blends decreases generally;in addition,it is differences to the silica content of different biom... |
