Title (EN) SOLID FUEL FURNACE
(FR) APPAREIL A COMBUSTION POUR COMBUSTIBLES SOLIDES
Abstract: front page image
(EN)The invention relates to a method for combustion of solid fuels, comprising the steps of feeding the fuel to a grate (1) in a combustion furnace, providing by primary oxygenation a primary combustion of the fuel while forming a bed of embers and releasing combustible gases, and circulating the released combustible gases for subsequent secondary oxygenation and combustion of the same. The method also comprises the additional step of circulating the combustible gases in a vertical plane about a substantially horizontal, imaginary rotational axis. The invention also relates to a solid fuel furnace for carrying out the method.
(FR)L'invention concerne un procédé permettant de brûler des combustibles solides, qui comprend les étapes suivantes: le combustible est amené à une grille (1) dans un four de chauffage; une première combustion, produite par oxygénation primaire du combustible, entraîne la formation d'un lit de braises et la libération de gaz combustibles; et les gaz combustibles libérés sont mis en recirculation en vue de leur oxygénation secondaire et de leur combustion. Le procédé comporte une étape supplémentaire, qui consiste à faire circuler les gaz combustibles dans un plan vertical autour d'un axe de rotation imaginaire sensiblement horizontal. L'invention concerne également un appareil à combustion pour combustibles solides permettant la mise en oeuvre dudit procédé.
