Key factors to minimise emissions from parallel flow regenerative lime kilns

Emission reduction is a significant topic in the lime industry. This article concentrates on NOx formation in PFR lime kilns, as these kilns provide the highest thermal efficiency of all kiln types. It goes on to share with its readers the conclusions drawn from years of research and development by Maerz Ofenbau AG, on how to reduce NOx formation, thereby minimising emissions and contributing to a healthier environment.

1 Introduction

Directive 2010/75/EU of the European Parliament, adopted on November 24th, 2010, lays down rules for EU member states on the integrated prevention and control of pollution arising from industrial activities.
