Zusammenfassung:	In a method for the combustion management in firing installations, in which a primary combustion gas quantity is conveyed through the fuel into a primary combustion area, part of the waste gas flow is extracted in the rear grate area and returned to the combustion process in the form of internal recirculation gas. In this case, no secondary combustion gas is supplied between the grate and the supply of the internal recirculation gas. A firing installation for carrying out this method features nozzles above the firing grate such that no air supply is arranged between the firing grate and the nozzles. Selon une méthode de gestion de combustion dans des installations dallumage, une première quantité de gaz de combustion principale est transportée dans le carburant vers une zone de combustion principale, une partie dun écoulement de gaz brûlé étant extraite dans la zone de grille arrière et renvoyée au procédé de combustion en forme de gaz de recirculation interne. Dans ce cas, aucun gaz de combustion secondaire nest alimenté entre la grille et la source de gaz de recirculation interne. Une installation dallumage pour exécuter la méthode comprend des buses au-dessus de la grille dallumage, de sorte quaucune source dair ne soit placée entre la grille dallumage et les buses.
