Kiln and Precalciner Enrichment
Improve combustion with oxygen enrichment
Oxygen enrichment is a flexible, efficient, and cost-effective technology that can improve combustion in all types of kilns and precalciners. Oxygen is required for any combustion process and enhances the combustion of all fuels. By increasing the oxygen concentration of combustion air through the addition of relatively pure oxygen, flame temperatures rise, heat transfer rates improve, and overall combustion efficiency increases. Even a small increase in oxygen concentration can have a dramatic impact on kiln and precalciner operations. Whether you are trying to increase production or lower your fuel costs, by burning alternative fuels more efficiently, oxygen injection can help.

Benefits of oxygen enrichment in kilns, especially when substituting difficult-to-burn fuels for coal, include:
- improved burning zone control
- greater kiln stability
- lower emissions
- ability to overcome ID fan limitations
Benefits of oxygen enrichment in the precalciner include:
- minimized impact on pressure drop and residence time
- increased alternative fuel utilization
- ability to overcome ID fan limitations
- maintained or improved calcination rates
