Calciner Firing Systems

The introduction of the calciner transformed the cement production process. Short kilns and tall preheater towers replaced long kilns; a change that dramatically improved process efficiency. But it also came with a challenge. Calciner temperatures are much lower than those in the kiln – and this posed a conundrum for calciner burner design. How do you still achieve fast ignition and …

PYRO-PROGRESSING

a sufficient amount of kiln dust acting as a catalyst. The abatement-inhibiting influence of water can only be reduced slightly as the water content in the rotary kiln exhaust gases is primarily dependent on the type and composition of the kiln fuel. To achieve best possible reduction premises, Pyroredox makes use of the Boudoard reaction.

Dynamic simulation of a pilot rotary kiln for charcoal …

A pilot rotary kiln is a cylinder that rotates around its longitudinal axis and operates essentially as a heat exchanger. The cylinder is lightly inclined (i.e., slope about 2–6%) to facilitate the axial displacement of the solid bed, which moves towards the discharge end as the hot gases circulate counter-current mode. Fig. 1 shows a scheme of the rotary kiln.

Preheater

Every cement plant needs a preheater. But what exactly is it? Think of it like a big box. A big box that holds a number of different machines. Combined, these machines kick off the pyroprocess. It might sound a simple concept. But putting the pieces together to achieve best-possible performance requires an expert understanding not only of the process but of factors like final …

Cement Kilns: Design features of rotary kilns

The rotation of the kiln lifts the feed up the side of the kiln, and the energy required to maintain its centre of gravity above the lowest (6 o'clock) point is the main component (80-90%) of the energy consumed. In the case of kilns containing curtain chains, these also produce an eccentric load. Rotary kilns have always had variable speed drives.

Pyroredox

The second essential step is to extend fuel residency time – by about four seconds – in the CO-rich atmosphere of the Pyroredox ®.This allows the CO to react with the NO X in the kiln exhaust gases and reduce them to CO 2 and harmless N 2 nitrogen.. After the kiln exhaust gases have been reduced, the remaining lean gas is fed into the calciner, where oxygen-rich tertiary air …
