Cement Kilns Firing systems

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 as-received state. With the advent of the rotary kiln it was necessary to develop sophisticated means of preparing the fuel and injecting it into the kiln system.
