Title
(EN) APPARATUS AND METHOD FOR CLEANING REGENERATIVE-BURNER MEDIA BED
(FR) APPAREIL ET PROCEDE DE NETTOYAGE D'UN LIT DE BRULEUR REGENERATIF
Abstract
(EN) A regenerative burner device for a furnace and a method of removing contaminants from such a device. The burner device includes a burner for introducing heat and waste gas into a furnace during ignition when supplied with fuel and a combustion gas, a media bed comprising refractory particles, and ducting for delivering combustion gas to said burner during ignition, and for drawing waste gas from said furnace on termination of ignition. The ducting causes the combustion gas and the waste gas to pass in succession through the media bed. Means are provided for periodically delivering a rapid flow of a decontaminating gas into said media bed. The rapid flow is of sufficient force to dislodge contaminants collected in the media bed from said waste gas.
(FR) L'invention concerne un dispositif à brûleur régénératif utilisé dans un four, ainsi qu'un procédé d'élimination des contaminants d'un tel dispositif. Le dispositif à brûleur comprend un brûleur permettant d'introduire de la chaleur et un gaz résiduel dans un four pendant l'allumage lorsqu'il reçoit du combustible et un gaz de combustion, un lit contenant des particules réfractaires, et un conduit permettant de distribuer le gaz de combustion audit brûleur pendant l'allumage, et d'extraire le gaz résiduel du four à la fin de l'allumage. Le conduit permet au gaz de combustion et au gaz résiduel de passer successivement dans le lit. Des moyens servent à distribuer périodiquement un flux rapide de gaz de décontamination dans ledit lit. Ce flux est suffisamment fort pour déloger les contaminants logés dans le lit du gaz résiduel.
