Abstract

High temperature heat and mass transfer and chemical kinetics are modeled in polydisperse cloud of coal particles taking into consideration reactions in pores and Stefan flow at the surface. Burning characteristics are calculated of bimodal aerosol, with the assumption of equal mass concentration of two fractions with two or three-fold difference between the mean particles diameters. It is shown that ignition delay of coarse particles in bimodal aerosol is significantly less than that of equal size particles in monodisperse aerosol. Also a burning time of fine particles is substantially less in bimodal aerosol. It is demonstrated that burning temperature is higher in case of bimodal aerosol in comparison with monodisperse one.
