heal.abstract	A two-dimensional, two-phase combustion model of pulverized coal char is presented in this paper. It is of particular importance to reveal the controlling mechanisms, through prediction of the diffusion and reaction rates and to evaluate the effect of initial coal-particle size on the performance of the burner. The partial differential equations of conservation of mass, momentum, energy and chemical species are solved taking into consideration turbulent flow, interphase mass and heat transfer, radiative heat transfer and operational conditions such as coal feed and primary and secondary air. The equations are integrated with the finite volume methods and are solved for the flow held, temperature field of gaseous and solid phases and the concentration of reactants and products. The results are compared with experimental data from the literature and the comparison is satisfactory. (C) 1998 Elsevier Science Ltd. All rights reserved.	en
