Title (EN) AIR STAGED LOW-NOx BURNER
(FR) BRULEUR A FAIBLE TAUX D'EMISSION DE NOx A COMBUSTION ETAGEE
Abstract:
(EN) An apparatus and method for using staged air combustion. The apparatus includes a burner body (10) secured to a port block (42), and a fuel passageway (12) extending through the burner body (10), terminating in a fuel nozzle (22), which injects fuel into the burner throat (40). Primary air jets (20) are configured to inject primary air into a primary combustion region (24), which is normally in the burner throat (40). A dish with a dish surface (28) is connected to the burner throat (40); the dish surface (28) extending in a divergent angle with respect to a burner centerline (35). Secondary air jets (34) are connected to the air passageway (14) and extend through the port block (42). The secondary air jets (34) inject secondary air into a secondary combustion region (38), which may be at the dish surface (28) or the hot face (30) of the burner.
(FR) L'invention concerne un appareil et un procédé qui mettent en oeuvre une combustion étagée. L'appareil comprend un corps de brûleur (10) fixé à un bloc à orifices (42), et un conduit d'acheminement (12) du combustible traversant le corps de brûleur (10) et aboutissant à un injecteur (22) de combustible, lequel injecte le combustible à l'intérieur du col (40) du brûleur. Des gicleurs d'air primaire (20) sont configurés pour injecter de l'air primaire à l'intérieur d'une zone de combustion primaire (24) généralement située dans le col (40) du brûleur. Une cuvette présentant une surface (28) de la cuvette est assemblée au col (40) du brûleur. La surface (28) de la cuvette s'étend dans un angle divergent relativement à la ligne médiane (35) du brûleur. Des gicleurs d'air secondaire (34) sont reliés au conduit d'air (14) et s'étendent à travers le bloc à orifices (42). Les gicleurs d'air secondaire (34) injectent de l'air secondaire à l'intérieur d'une zone de combustion secondaire (38) pouvant être située sur la surface (28) de la cuvette ou sur la face chaude (30) du brûleur.
