05.05.2015The conclusion is that, for a cement plant with a raw meal feed of 3355 t/h and the addition of 1500 m 3 /h of oxygen, 8% more fuel can be added in the calciners. This allows for a 116% addition of raw meal while maintaining product quality. Another consequence is that the temperature profile of the process changes.

Most substantial thermo-chemical reactions of the cement process occur in the riser ducts and in the calciner(s) and certainly in the sintering zone of the kiln. Modern suspension preheater kilns usually have 1 or 2, in a few cases also 3 strings with 4 or 5 stages. Recently, A TEC has modified some kilns to 6 stages.
