摘要
从煤的物理特性研究煤灰结渣特性 ,煤中所含各类物质中 ,铁化合物具有最低的熔化温度 ,易在炉膛内燃烧中产生结焦。本文提出了一种根据磁铁对煤的磁力吸附百分比来判别不同煤种煤的结渣倾向的新方法 ,并对这种方法的机理和应用进行了深入分析。
Coal-ash slagging characteristics are studied from the perspective of coal physical properties. Among the various kinds of substances present in the coal, iron compounds have the lowest melting temperature, which is the major cause of coal related slagging during coal firing in a boiler furnace. This paper describes a new method for determining the slagging tendency of various kinds of coal on the basis of a magnetic absorption percent of magnetic iron to coal. Furthermore, an in depth analysis is conducted of the mechanism and use of the above method, which makes possible the rapid measurement on site of the coal slagging characteristics.
