As such coal storage during cement manufacturing is an important component to consider in hazard analysis. Among the various causes of coal fires, spontaneous combustion during storage results in a large number of losses. Spontaneous combustion is caused by adsorption of oxygen at the outer and inner surface of coal which results in oxidation.
