Abstract It has recently been recognized that fly ash from coal combustion in utility boilers has a bimodal distribution (1-7). The larger particles are produced by fusion and coagulation of the mineral inclusions in coal; the smaller particles, in the submicron range, are produced by the vaporization and condensation of the mineral constituents. Several field and laboratory studies have been conducted to determine the factors that govern the physical and chemical state of submicron particles (4,5,8,9). These studies will be reviewed during the presentation. In this paper we will show, drawing partly on results in previous studies (3,4,10), that a detailed knowledge of the temperature history of coal particles during combustion is needed for the purpose of understanding ash vaporization.
