Abstract：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.
