- Abstract
Time dependences of the diameter and density of burning single porous coal particles have been investigated. Using as an example a coke particle of the Nazarovsk coal, it is shown that in the course of combustion of such a particle the product of its density by the square of its diameter decreases linearly. A new combustion constant of coal is suggested. An analytical substantiation of the empirical dependence of the time of combustion of coal coke particles on their initial dimensions and densities, oxygen content in them, and on the gaseous mixture temperature has been carried out.
