Abstract

La présente invention a pour objet un système de brûleur ayant une chambre de résonance qui se trouve à l'intérieur d'une chambre de mélange, dans lequel le bruit d'écoulement d'un fluide généré au cours du mélange de l'air et d'un gaz à l'intérieur de la chambre de mélange est atténué par l'utilisation d'une action résonnante, permettant ainsi un fonctionnement silencieux d'une chaudière à gaz ou d'un chauffe-eau à gaz. À cette fin, un système de brûleur pour une chaudière à gaz ou un chauffe-eau à gaz, qui est constitué par un brûleur destiné à brûler un fluide de mélange air-gaz, un corps de brûleur accouplé au brûleur pour former une chambre de mélange destinée à mélanger l'air et le gaz, une soufflante destinée à fournir l'air ou le fluide de mélange air-gaz au brûleur, et un tuyau de raccordement pour fluide de mélange positionné entre le corps de brûleur et le brûleur, comporte principalement : un tuyau faisant saillie ayant une extrémité accouplée au tuyau de raccordement pour fluide de mélange et l'autre extrémité pénétrant au travers d'un côté du corps de brûleur et se trouvant en une position vers un intérieur de la chambre de mélange ; et un capot de chambre de résonance sur lequel pénètre l'autre extrémité du tuyau faisant saillie, et qui communique avec la chambre de mélange et comporte un bord accouplé sur une surface intérieure du corps de brûleur de manière à former une chambre de résonance pour atténuer le bruit généré au cours de l'écoulement de l'air et du gaz à l'intérieur de la chambre de mélange.
