Abstract
Sur un brûleur comprenant une chambre de combustion 4 allongée munie à sa face supérieure de becs, sont prévus entre ces becs des tubes de refroidissement 7 disposés perpendiculairement à l'axe du brûleur et inclinés suivant des plans verticaux. Il est particulièrement avantageux s'il s'agit d'une chambre de combustion 4 d'un chauffe-eau, baignée par l'eau à chauffer, les deux extrémités des tubes de refroidissement 7 perçant la paroi 3 de la chambre 4 et l'eau du chauffe-eau circulant dans lesdits tubes pour refroidir la zone de combustion 6 du brûleur. La circulation de l'eau dans les tubes de refroidissement 7 est assurée par voie thermodynamique, l'inclinaison des tubes alternant en direction d'un tube à l'autre pour obtenir une circulation à contre-courant dans des tubes 7 voisins.On a burner comprising an elongated combustion chamber 4 provided at its upper face with nozzles, there are provided between these nozzles cooling tubes 7 arranged perpendicular to the axis of the burner and inclined along vertical planes. It is particularly advantageous if it is a combustion chamber 4 of a water heater, bathed in the water to be heated, the two ends of the cooling tubes 7 piercing the wall 3 of the chamber 4 and the water from the water heater circulating in said tubes to cool the combustion zone 6 of the burner. The circulation of water in the cooling tubes 7 is ensured by thermodynamic means, the inclination of the tubes alternating in the direction of one tube to another to obtain a circulation against the current in neighboring tubes 7.
