Cement Kilns: Firing systems

"Firing" in cement industry parlance is the supply of heat to a kiln by use of a burning fuel. Throughout the early history of the industry, fuel was added to static kilns in lump form, pretty much in its "asreceived" state. With the advent of the rotary kiln, it was necessary to develop sophistied means of preparing the fuel and injecting it into the kiln system.
