Coal is often the main fuel source used to heat the cement kiln. Coal pulverizers are required to grind the coal from the bulk storage size to a smaller particle diameter to use in the kiln. Coal pulverizers significantly reduce the mean particle size of the coal, drastically increasing the fire/explosion hazard risk.
2.3 Pulverizer Designs and Pulverized Coal Handling. Coal preparation predated pulverized coal firing, particularly for stoker units where sizing has always been very important, particularly in the minimizing of fines. Predating the development of pulverized coal firing came the development of pulverizers used in the processing of minerals.
Boilers for steam generation in power plants and process industries use coal as fuel. The percentage of boilers operating with coal as fuel outnumbers the boilers using all other fuels combined. Coal is pulverized before firing for achieving a stable and efficient combustion. Many types of pulverizers are used in boilers by different designers.
