Cement Kilns: Firing systems

2019-05-20· "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.

The cement kiln

Since meal enters the kiln at about 900 C, (compared with about 20 C in the wet process), the kiln can be shorter and of smaller diameter for the same output. This reduces the capital costs of a new cement plant. A dry process kiln might be only 70m long and 6m wide but produce a similar quantity of clinker (usually measured in tonnes per day) as a wet process kiln

Cement Kilns: Precalciner kilns

2019-03-14· Today, nearly all new kilns installed have precalciners. They represent the final improvement in efficiency, and hold out the prospect for nearly total elimination of heat wastage from cement kilns. The precalciner system is a suspension preheater in which, in addition to the kiln flame, extra fuel is burned in the base of the preheater. The first kilns of this kind operated in Japan in the

fine pet coke in kiln firing Gastouderopvang Lydia

Pet coke in cement clinker,* The level of substitution of pet-coke in an existing kiln (having no by-pass arrangement) is decided on the basis of sulphur content in pet-coke and clinker,* Another method which is being used widely, is to blend pet-coke with the fuel firing in calciner and kiln In this method of use, it must be ensured .

Increased use of alternative fuel in the main firing

Increased use of alternative fuel in the main firing system of rotary cement kilns. When producing cement, most of the thermal energy is required for burning the cement clinker in rotary kiln plants. At present, fossil fuels and alternative fuels (or secondary fuels) are used in parallel for this purpose.
