A Mathematical Model for Unsteady State Coal Particle Combustion

摘要

Empirical formulas for volatilization, swelling and chemical reaction rate are obtained by experiments using the laser heating technique. Emissivity of coal particle is measured at high temperatures. An unsteady state combustion model of a single coal particle, which accounts for the homogenous reaction in surrounding gas, is developed using the parameters. Single coal particle combustion is analyzed using the model.
