Title
(EN) DEVICE AND METHOD FOR CONTINUOUS COMBUSTION OF COMBUSTIBLE MATERIAL IN A PYROLYTIC CHAMBER
(FR) DISPOSITIF ET PROCÉDÉ DE COMBUSTION CONTINUE D'UN MATÉRIAU COMBUSTIBLE DANS UNE CHAMBRE PYROLYTIQUE
Abstract
(EN)
The present invention relates to a device (1) for combustion of a combustible material, com-prising, inner walls (3) and outer walls (4), creating a double wall space (15) in between, which double wall space is provided with at least one primary air inlet (8), a top wall (17) having at least one top opening (10), an inclined tubular means (2), which tubular means (2) further comprises an inlet (5) for the combustible material in the upper part of the in-clined tubular means (2), an inlet cover (51), a pyrolytic chamber (6) located on the inside of the inner wall (3) of the tubular means, an outlet (7) in the lower part of the inclined tubular means, and an outlet cover (72), and wherein the double wall space (15) comprises a secondary air distribution zone (9) for distribution of hot air and facilitating mixing of py-rolytic gases, leading to a combustion zone (11), and a flame zone (12), adjacent to the top opening, and wherein at least one of the inner walls (3) comprises through holes (13) to let hot air flow into the secondary air distribution zone (9). A method for combustion of a bio-logical material in a device according to the invention is also described, and further collect-ing biochar from the device.
(FR)
La présente invention concerne un dispositif (1) pour la combustion d'un matériau combustible, comprenant des parois internes (3) et des parois externes (4), créant un espace double paroi (15) entre elles, lequel espace double paroi est pourvu d'au moins une entrée d'air primaire (8), d'une paroi supérieure (17) ayant au moins une ouverture supérieure (10), d'un moyen tubulaire incliné (2), lequel moyen tubulaire (2) comprend en outre une entrée (5) pour le matériau combustible dans la partie supérieure du moyen tubulaire en position ouverte (2), d'un couvercle d'entrée (51), d'une chambre pyrolytique (6) située à l'intérieur de la paroi interne (3) du moyen tubulaire, d'une sortie (7) dans la partie inférieure du moyen tubulaire incliné et d'un couvercle de sortie (72), et l'espace double paroi (15) comprenant une zone de distribution d'air secondaire (9) pour la distribution d'air chaud et facilitant le mélange de gaz pyrolytique, conduisant à une zone de combustion (11) et une zone de flamme (12), adjacente à l'ouverture supérieure et au moins l'une des parois internes (3) comprenant des trous traversants (13) pour laisser passer l'air chaud dans la zone de distribution d'air secondaire (9). L'invention concerne également un procédé de combustion d'un matériau biologique dans un dispositif selon l'invention et en outre de collecte de biocharbon à partir du dispositif.
