Oxygen Enrichment System for Cement and Lime Producers

Improved performance that can help lower your overall costs

Oxygen enrichment is a flexible, efficient, cost-effective technology that can help improve your operation's profitability. With minimal capital investment, you can increase production and use of alternative and waste fuels, decrease emissions, and improve overall kiln efficiency. Since alternative fuels can be harder to burn and less consistent than traditional fuels, they can limit kiln operations and capacity. Our oxygen combustion technologies allow alternative fuels to burn more efficiently and at higher temperatures, enabling you to increase alternative fuel substitution to help reduce operating costs and meet sustainability targets.

“Is there a solution to help me increase production when my ID fan is maxed out?”
Adding oxygen to the kiln or precalciner can increase energy to the kiln, enabling 10-20% increased production with very low capital costs. Upsets are more easily avoided and recovery from upsets is significantly quicker--meaning more product on spec.
