This research aims to study the problems of the rotary kiln of al Kufa cement plant. The heating process of the furnace starts by burning a certain amount of wood near the fuel outlet inside the rotary kiln to provide the initial combustion process of the heating oil at 80-100 C.
How to Clean Kiln in Rotary Kiln
The definition of rotary kiln cleaning is during kiln maintenance, people should burn the empty kiln first. The process of burning the empty kiln is called kiln cleaning. Four to eight hours before ceasing the fire, inform the coal mill to stop sending coal to the coal bunker in order to burn the empty bunker.

Cement Kilns Design features of rotary kilns
The early commercially successful rotary kilns in Britain were nearly all straight cylinders, the exceptions being those at Norman 1904. Lengthening of the early kilns at Wouldham and Bevans resulted in kilns with enlarged burning zones, while the lengthened kilns at Swanscombe had enlargements at both ends. Among new installations from 1909 to 1914, only 15 out of 44 were
Temperature Measurement for Cement amp Lime Kilns

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.
