Abstract
A method for drying coal in a coal mill and pneumatically conveying it to a kiln for burning, with a portion of the coal-dust-laden air generated thereby being diverted to a clinker cooler adjacent the kiln in order to ignite the suspended particles and supply hot air for burning the coal. The diverted air is later recirculated back to the coal mill to help dry the coal.
