Coal Dust Explosions in the Cement Industry

For many cement producers in the United States, the conversion from fuel oil and natural gas to pulverized coal has been difficult, frustrating, and in a few cases, very costly. This study deals mainly with coal safety requirements in the cement industry which accounts for a very small percentage of coal usage in pulverized coal firing systems.
