Abstract
The mechanism of submicron particle formation during pulverized coal combustion is examined. Residual ash particles formed by the coalescence of molten ash droplets on the burning carbon surface and the break-up of the burning coal particles account for most of the aerosol mass. The sizes of these large particles are related to the sizes of coal particles burned. Some of the ash vaporizes at the high temperatures of pulverized coal combustion. Large numbers of submicron particles may be produced by nucleation of these ash vapors or other species. These fine particles appear to coagulate more rapidly than is explained by Brownian coagulation even when interparticle dispersion forces are considered. Imperfect mixing may also accelerate coagulation. Calculated particle size distributions are compared with data obtained upstream of gas cleaning equipment of utility boilers.
