Level and pressure instrumentation for the cement
To produce cement, the raw meal is burned to clinker in a long rotary kiln. After leaving the rotary kiln, the clinker has a temperature of up to 1300 C and must be cooled down to a temperature of about 200 C for further storage. To achieve this, the clinker bed is cooled with a continuous stream of air. Pressure

Cement Kiln an overview ScienceDirect Topics
A cement kiln flue gas recovery scrubber project was located at Dragon Products Companys coal-fired cement kiln in Thomaston, Maine. One of the problems at this plant was that about 10 of the kiln product was cement kiln dust CKD, an alkali-rich waste that, because of its potassium content, cannot be blended with the cement product.
Alternative Fuel Use in Cement Manufacturing
blending with mineral substitutes, and using lower-carbon alternative fuels to fire the kiln. Canadas cement industry has made progress over past two decades in each of these areas. Energy intensity improved by 21 between 1990 and 2010. There have also been improvements in the clinker-to-cement ratio and the use of alternative fuels is growing.

The cement kiln
A development of this process is the precalciner kiln. Most new cement plant is of this type. The principle is similar to that of the dry process preheater system but with the major addition of another burner, or precalciner. With the additional heat, about 85-95 of the meal is decarbonated before it enters the kiln ...

Surely there are a number of plants using oxygen enrichment technique but still not commercially due to its high cost. If market demand exists with good prices for cement then oxygen enrichment can be a good option. Table-1 shows a number of rotary kilns in the USA using oxygen enrichment of either the main burner or the precalciner.
