TLDR
In this article, the authors extended Essenhigh and Csaba's model for plane flame propagation through a coal dust cloud to incorporate heat generation due to chemical reaction, and they used the nonlinear differential energy equation to evaluate burning velocity, temperature profile, and the heat generation rate along the flame axis.About:

Coal dust flames: A review and development of a model for flame propagation
TL;DR: A review of coal dust combustion as reported in the literature is presented in this article, and a mathematical model of flame propagation through coal dust-air mixtures is developed in detail.

Prediction of ignition temperature of a single coal particle
TL;DR: In this paper, an analytical method based upon Semenov's thermal ignition theory for evaluating the ignition temperature of a single coal particle was presented, and an equation describing the temperature-time history of the particle has also been developed.
Journal ArticleDOI
Propagation of laminar pulverized coal-air flames
TL;DR: In this paper, a generalized model for a flame propagating in laminar, premixed particle-gas mixtures was formulated, assuming particlegas dynamic equilibrium and uniform pressure, and the unsteady state equations were solved numerically using finite-difference techniques.
Journal ArticleDOI
Combustion and flame propagation in coal systems: A review
TL;DR: In coal combustion, coal flames propagate by several mechanisms, including boundary layer diffusion, pore diffusion, surface reaction with alternatives of adsorption control or desorption, or some intermediate.
