Mixing Air Technology
Mixing Air is a significant advance in the area of cement kiln emissions reduction. 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.
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. When Mixing Air is added, stratified kiln gasses begin to rotate and mix. This rotation improves combustion, serves to reduce emissions and improves the overall stability of the kiln.
