Design and Application of Low-NOx Burners in Rotary Kilns

Abstract

In an era of heightened environmental consciousness and stringent pollution controls, the reduction of air pollution, particularly nitrogen oxides (NO_x), has emerged as a universal goal. In response to the increasingly rigorous NO_x emission standards for industrial furnaces, our innovative research has yielded a groundbreaking solution. By engineering a novel five-channel vortex low NO_x burner and implementing it in a company’s lime rotary kiln, we have achieved a remarkable reduction in NO_x emissions. The average NO_x content in the kiln’s tail gas, previously at 450mg/m³ and in violation of industry standards, has now been successfully decreased by over 30%. This cutting-edge burner technology not only ensures compliance with environmental regulations but also reaches a record-low NO_x emission concentration of 135.56 mg/m³ during operation, effectively demonstrating our commitment to and success in controlling NO_x emissions. This breakthrough marks a significant contribution to the field of industrial environmental protection and showcases our leadership in developing sustainable industrial practices.
