Flame propagation velocity is one of the basic physical quantities to evaluate flame stability. We developed a model analyze for pulverized coals. The relationship between coal concentration and was calculated using properties, diameter, initial gas composition, temperature surrounding gas, radiant heat flux from surroundings particles. In present study, we examined relationships such burning conditions by fundamental experiments then empirical formulas. Furthermore, also influence particle diameter distribution. compared results experimental results; could reproduce results.
