Abstract

L'invention porte sur un dispositif de distribution de gaz (100), sur une chambre de combustion comprenant ce dernier, et sur un chauffe-eau. Le dispositif de distribution de gaz (100) comprend : de multiples tuyaux de distribution de gaz (1) qui sont parallèles les uns aux autres et disposés suivant certains intervalles, et qui sont chacun pourvus de multiples buses à gaz (2); et au moins un tuyau d'alimentation en gaz (3) en communication avec les tuyaux de distribution de gaz (1) de manière à relier ces derniers sous la forme d'une structure intégrée, le tuyau d'alimentation en gaz (3) servant à alimenter en gaz les tuyaux de distribution de gaz (1), et étant pourvu d'une interface d'alimentation en gaz (4), et l'interface d'alimentation en gaz (4) servant au raccordement d'un clapet d'admission. Étant donné que le dispositif de distribution de gaz (100) est en communication avec les tuyaux de distribution de gaz (1) au moyen du tuyau d'alimentation en gaz (3), et le tuyau d'alimentation en gaz (3) est relié d'un seul tenant aux tuyaux de distribution de gaz (1), le tuyau d'alimentation en gaz (3) peut délivrer de manière synchrone la même quantité de gaz aux tuyaux de distribution de gaz (1), de telle sorte que la teneur en gaz dans chaque tuyau de distribution de gaz (1) est bien répartie, ce qui permet à une flamme sortant du dispositif de distribution de gaz (100) d'être plus stable.
