Higher temperature oxygen-rich gasses tend to travel along the top of the kiln while cooler, carbon dioxide-rich gasses tend to travel along the bottom. This gas stratification actually inhibits the combustion process, limits alternative fuel usage and contributes to emissions.

When Mixing Air is added, opposing streams of high velocity air cause the stratifed kiln gas layers to rotate and mix. This rotation improves combustion, serves to reduce emissions and improves the overall stability of the kiln.

Mixing Air is a significant advance in the area of cement kiln emissions reduction. Not only does Mixing Air allow maximum alternative fuel usage, operational tests and actual operating data have shown that Mixing Air can reduce NOx emissions by 50% while significantly reducing SOx, CO and other emissions.

Mixing Air is equally effective on preheater/precalciner kilns as well as long kilns.

In addition to lower emissions, Mixing Air Technology improves Kiln Stability resulting in:

1. Increased production
2. Better product quality
3. Less sulfur buildup
4. Improved thermal efficiency
