uses coal as the primary fuel. Conversion to coal was started in the 1970's. In 1972, only 39 percent of the industry's energy was supplied by coal. • Inland Cement, "We are also concerned about the potential fire and explosion hazard of working with coal and are confident that we can use coal safely.
Fly ash or flue ash, also known as pulverised fuel ash in the United Kingdom, is a coal combustion product that is composed of the particulates (fine particles of burned fuel) that are driven out of coal-fired boilers together with the flue gases.Ash that falls to the bottom of the boiler's combustion chamber (commonly called a firebox) is called bottom ash.

Coal-derived coke was the fuel used in most static kilns and so was the dominant fuel in the cement industry in the nineteenth century. Coal could not be used in static kilns in which the fuel is fed in with the raw material, mainly because, during the gradual heat-up of the charge, the fuel's volatiles are lost without ignition, so wasting up ...
The Cement/Lime industry has had to search for a way to reduce costs and this has resulted in the near standardization of coal-fired (or coke) systems for firing up the kiln. These systems are indirect-fired, where coal is crushed in mills/pulverizers, then classified by size for collection as a fuel or dust through a heated air conveyance network.

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.
Mining of coal leads to coal dust, and flour mills likewise have large amounts of flour dust as a result of milling. A gigantic explosion of flour dust destroyed a mill in Minnesota on May 2, 1878, killing 14 workers at the Washburn A Mill and another four in adjacent buildings.
