On average 0.2 – 0.3 tonnes of coal are consumed in the kiln per kilogram of clinker cement production. 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.
cement industry is significant compared to other manufacturing industries, it is the fuel used during the calcination of raw materials in the kiln that accounts for the greatest energy consumption in the cement-making process and this is a deciding factor in the cost of production.
