Oxygen enrichment of lime and cement kilns

The enrichment of primary combustion air in lime and cement kilns allows for increased throughput and enhanced product quality. The addition of oxygen increases the front-end kiln temperatures and as a result enhances the temperature profiles. The use of oxygen can result in the reduction of total reduced sulfur (TRS) and/or carbon monoxide (CO).
