Self-deNOx calciner development and application

02 March 2026

Against the backdrop of the global cement industry’s pursuit of “dual carbon” goals and increasingly stringent environmental emission standards, traditional end-of-pipe NOx treatment technologies are struggling to meet sustainable development needs due to their high investment and operational costs, and issues of secondary emissions. Technological development now focusses on modifying the pyroprocessing system to achieve self-denitrification (“self-deNOx”).
