As with so much else in the cement sector, the exact reasons for a critical temperature increase differ from kiln to kiln, plant to plant and country to country. However, the main possible effects are the same everywhere: Increasing shell temperatures can lead to hot spots and, often, the need to stop the kiln.
A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together.

Formation and Techniques for Control of Sulfur Dioxide and . the cement kiln system Sulfur in cement kilns is derived from both kiln feed and from the kiln fuel The form of the sulfur dictates the location in the kiln where the SO2 generation takes place Sulfur in the fuel is oxidized in the burning zone or calciner and is easily removed by reactive lime present in the kiln
Electric kilns are notorious for poor airflow, but understandably so (sucking air through them drastically affect efficiency). Gas kilns, on the other hand, have a natural draft that is a part of their combustion process. Boiling point hold: Conceptually a firing should take ware to near the boiling point and hold it there for a period of time.
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to readymix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.
