Title
(EN) SUPPLEMENTAL BURNER FOR CONVERSION OF BIOMASS AND RELATED SOLID FUEL
(FR) BRÛLEUR SUPPLÉMENTAIRE POUR LA CONVERSION DE BIOMASSE ET D'UN AUTRE COMBUSTIBLE ASSOCIÉ
Abstract
(EN)
A conversion burner, a system of conversion burners, and a method of conversion of a solid fuel selected from at least one of biomass and peat. The burner is constructed and arranged to be affixed to a combustor, and comprises a housing defining a burner chamber; a grate within the burner chamber defining an upper chamber region and a lower chamber region; at least a first solid fuel inlet; at least a first air inlet operatively connected to the upper chamber region and connectable to a first air source; a product gas outlet operatively connected to the combustion region of the combustor; and at least one waste outlet. The product gas is delivered to the combustor for firing or co-firing, overcoming fouling problems which result from direct delivery of solid fuel to the combustor, and problems raised by remote conversion or storage of solid fuel.
(FR)
L'invention concerne un brûleur de conversion, un système de brûleurs de conversion, et un procédé de conversion d'un combustible solide choisi parmi au moins de la biomasse et de la tourbe. Le brûleur est construit et agencé de manière à être fixé à une chambre de combustion, et comprend un boîtier définissant une chambre de combustion; une grille à l'intérieur de la chambre de brûleur définissant une région de chambre supérieure et une région de chambre inférieure; au moins une première entrée de combustible solide; au moins une première entrée d'air reliée de manière opérationnelle à la région de chambre supérieure et pouvant être connectée à une première source d'air; une sortie de gaz produit reliée de manière opérationnelle à la région de combustion de la chambre de combustion; et au moins un orifice de sortie de déchets. Le gaz produit est délivré à la chambre de combustion pour l'allumage ou le co-allumage, surmontant les problèmes de salissures qui résultent de l'administration directe de combustible solide dans la chambre de combustion, et les problèmes soulevés par la conversion à distance ou le stockage de combustible solide.
