Abstract

A numerical study of interrelated heat and mass transfer processes with consideration for the thermal reaction of the organic matter of fuel on the gas-phase ignition of coal particles with sizes from 50 to 500 μm in airflow was performed. Minimum air temperatures at which the ignition of volatile substances occurs in an oxidizing atmosphere were determined. The calculated values are lower than the level of maximum permissible temperatures in the individual sections of systems for the preparation of pulverized coal at coal-burning power plants.
