Emission Reduction with Innovative Oxygen Injection

Dec 11,  · A second example will introduce the injection of oxygen into a cement kiln to reduce CO slip from the combustion process. A key success factor in this application is the rapid and effective mixing of a relatively small oxygen flow into a much larger flue gas stream. Lastly, oxygen was injected into an aluminum re-melting furnace to reduce large

Predictive Model for Cement Clinker Quality Parameters

Managers of cement plants are gradually becoming aware of the need for soft sensors in product quality assessment. Cement clinker quality parameters are mostly measured by offline laboratory analysis or by the use of online analyzers. The measurement delay and cost, associated with these methods, are a concern in the cement industry. In this study, a regression-based model was developed to

Pillard DNOxFLAM™ - Fives in Combustion

Pillard DNOxFLAM™ kiln burner is Fives’ low-NO x solution for rotary kilns using direct firing systems. Thanks to a patented system located inside the burner, and no moving parts, the Pillard DNOxFLAM™ uses a fuel and air combustion staging principle, leading to an average of 20% NOx reduction compared to conventional direct firing monotube burners, while ensuring low operational costs
