Swirl Number For Cement Kiln Burner Definition

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 sophisticated means of preparing the fuel and injecting it into the kiln system.
