Precalciner Kiln

Cement Kilns: Precalciner 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 late 1960s. These systems allow more thermal processing to be accomplished efficiently in the preheater.

The cement kiln

Basic principle of a precalciner 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.

PRE-CALCINER IN CEMENT MANUFACTURING PROCESS - …

Precalciner (with cyclone preheater) Precalciner systems have been derived from the preheater kilns in that the decarbonation of the raw materials is further increased before introduction into the kiln.Thus, the degree of calcination at kiln inlet is much higher compared to that in preheater kiln.

The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly (1–4°) and slowly rotates on its axis at between 30 and 250 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of the kiln causes it to gradually move downhill to the other end of the kiln.

Cement kiln - Wikipedia

The rotary kiln consists of a tube made from steel plate, and lined with firebrick. The tube slopes slightly (1–4°) and slowly rotates on its axis at between 30 and 250 revolutions per hour. Rawmix is fed in at the upper end, and the rotation of the kiln causes it gradually to move downhill to the other end of the kiln. At the other end fuel, in the form of gas, oil, or pulverized solid fuel, is blown in through the "burner pipe", producing a large concentric flame in the lower part of the kiln tube. As material moves under the flame…

Cement Kilns: Rotary kilns

Precalciner kilns: Rotary Kiln Processes. With the arrival of rotary kilns in Britain in 1900, cement manufacturing processes became sharply defined according to the form in which the raw materials are fed to the kiln. Raw materials were either ground with addition of water, to form a slurry containing typically 30-45% water, or they were ground dry, to form a powder or "raw meal". In the Wet ...

So it is obvious that the precalciner (PC) kiln was developed from a straight suspension preheater (SP) kiln. The process characteristics (heat balance etc.) of both SP and PC kiln systems are quite similar, the main difference being the fact that in case of the PC kiln, 50 to 60% of the fuel (heat) is introduced via a chamber between kiln inlet and bottom cyclone. This allows to match the ...
