| 摘 要： | 为了解沉积于炉壁不同部位灰渣熔融温度的变化及分布特性，在实验炉内进行了两个工况的对比燃烧实验，通过对沿烟气行程灰沉积物熔融温度及化学成分和矿物相的分析，结果发现，距燃烧器出口155mm处炉壁灰渣的熔融温度最低，距燃烧器出口1000 mm~1150 mm炉壁灰渣熔融温度最高；灰沉积物熔融温度沿烟气行程呈先升高后降低的分布特点。这种分布特性与矿物元素的迁移、沉积是直接相关的，同时与燃烧负荷也有一定的关系。

| Abstract: | To investigate the distribution characteristic of melting temperature of ash deposits deposited on different locations of furnace wall,comparison test on two combustion work conditions was made in trial furnace of black liquor coal slurry.Analysis was made on melting temperature,chemical composition,and mineral phase of ash deposits on furnace wall along journey of fume.The result shows that melting temperature of ash deposits at 155 mm from outlet of burner on furnace wall is the lowest,and that of the hig... |
