The history of pulverization date back as early as 1824 and was envisaged by Carnot in a coal fired engine. In 1890 Diesel made use of pulverized coal in his diesel engine. The pulverized coal firing was first developed in cement industry which then migrated to power and process industries. Pulverizing coal in boiler is an important factor the overall cycle efficiency.
