Cement kiln - Wikipedia

Cement kilns are used for the pyroprocessing stage of manufacture of Portland and other types of hydraulic cement, in which calcium carbonate reacts with silica-bearing minerals to form a mixture of calcium silicates.Over a billion tonnes of cement are made per year, and cement kilns are the heart of this production process: their capacity usually defines the capacity of the cement plant.

Cement Kilns: Precalciner kilns

Precalciner cement kilns. As with conventional suspension preheater kilns, the gases leaving the top of the preheater are used for drying raw materials. Some heat is still wasted, because rawmills tend to run intermittently, since they are always designed with "overtaking capacity" to avoid restricting the output of the kiln.

Dalmia - Preheater

Kiln Inlet Chamber. The kiln inlet chamber (also called smoke chamber) is at the base of the preheater where the preheater ends and rotary kiln starts. Here, raw mix coming down from the preheater goes to the kiln and gases come from the kiln and go up the preheater. Due to continuous circulation of gases rich in alkali or sulphur, refractories ...

This turns the kiln very slowly, but enough to prevent damage. Internal heat exchangers. Heat exchange in a rotary kiln may be by conduction, convection and radiation, in descending order of efficiency. In low-temperature processes, and in the cooler parts of long kilns lacking preheaters, the kiln is often furnished with internal heat ...

Cement Kilns: Exhaust gas handling

The solids leaving a cement kiln system in suspension in the exhaust gases are called cement kiln dust (CKD). The clinker that is produced by cement kilns varies little in chemistry from one site or kiln to another, and it is a common fallacy to assume that CKD is similarly uniform. The nature of dust emitted is extremely sensitive to the ...

flame length and kiln shell temp - Page 1 of 2

Re: flame length and kiln shell temp. Dear sir, The length of the flame in general will be 2.5 - 3 times of kiln Diameter. B y increasingthe air pressure, burner tip velocity will be increased and consequently flamemomentum will be increased.Higher flame momentum will facilitate intimatemixing of fuel and air which lead to short,hot and strong flame.
