Title
(EN) AFTERBURNER FOR GAS FROM GASIFICATION PLANT
(FR) CHAMBRE DE POST-COMBUSTION POUR UN GAZ PROVENANT D'UNE INSTALLATION DE GAZÉIFICATION
Abstract
(EN)
The present invention relates to an afterburner for gas from a gasification plant. The afterburner provides an optimal mixture of combustible gas and air, permitting an optimal reaction between the 02 in the air and the gas and creating a mixture ratio that enables the load on a burner to be regulated without altering the mixture ratio between air and gas. This offers the possibility of optimal combustion even during regulation of the burner, over the whole of the relevant regulating range. The result is extremely good combustion and reduced emissions of 02, CO and NOx.
(FR)
L'invention concerne une chambre de post-combustion pour un gaz provenant d'une installation de gazéification. La chambre de post-combustion fournit un mélange optimal de gaz combustible et d'air, permettant une réaction optimale entre l'O2 dans l'air et le gaz, et créant un rapport de mélange qui permet à la charge sur un brûleur d'être régulée sans modifier le rapport de mélange entre l'air et le gaz. On obtient ainsi une possibilité de combustion optimale même pendant la régulation du brûleur, sur toute la plage de régulation applicable. Le résultat est une combustion exceptionnelle et des émissions réduites de O2, CO et NOx.
