Abstract

L'invention concerne un procédé de fonctionnement d'une chaudière industrielle (1) qui comprend au moins un brûleur (4) à combustible liquide et/ou gazeux disposé dans la partie basse du foyer (2) et un système d'injection d'air additionnel (5) à plusieurs buses d'injection (6) disposé en aval de l'ensemble des brûleurs (4).
Selon l'invention, l'ensemble des brûleurs (4) fonctionne en stoechiométrie ou en excès d'air d'au plus 5 % et en ce que l'air introduit par l'ensemble des brûleurs (4) et le système d'injection (5) représente un excès d'air d'au plus 15 %.
