Abstract (en)

[origin: CZ309513B6] A gasifier for solid fuels with a jet nozzle contains a gasification chamber (4) with a bottom (10), and a combustion chamber (9) is located below the gasification chamber. The bottom (10) of the gasification chamber (4) slopes towards its centre by four inclined walls (11) which form a pyramidal shape with the apex pointing to the combustion chamber (9) or form a trough, the gasification chamber (4) and the combustion chamber ( 9) are separated by a partition (5), which on the side of the gasification chamber (4) forms the bottom (10) of this gasification chamber and on the side of the combustion chamber (9) forms the upper inner wall (7) of this combustion chamber, the partition (5) being guided nozzle (2) the inlet opening (1) of which is in the bottom of the gasification chamber (4) and the outlet opening (3) is in the wall (7) of the combustion chamber (9). The inlet opening (1) of the nozzle (2) consists of a rectangular or square central slot (13) and rectangular radial slots (14), which are formed in the edges (12) between the inclined walls (11) of the bottom (10) of the gasification chamber (4). Under the central slot (13) there is a central vent (15) of nozzles (2) forming a through hole, and the radial slots (14) are connected by channels (8) which go into the central vent (15) which forms in the wall (7) ) combustion chamber (9) outlet hole (3). The channels (8) are sloped towards the central vent (15) at an angle of at least 40°, and the side walls (16) of the channels (8) are mutually opened towards their lower walls (17).

Abstract (de)

Die Erfindung betrifft ein Heizgerät für Festbrennstoffvergaser mit Radialdüse, einer Vergasungskammer (4) mit einem Boden (10), einer unterhalb der Vergasungskammer angeordneten Brennkammer (9), wobei der Boden (10) der Vergasungskammer (4) zu seiner Mitte hin geneigt und durch vier schräge Wände (11) definiert ist, die eine Pyramidenform mit zur Brennkammer (9) weisender Spitze oder eine Wannenform bilden, während die Vergasungskammer (4) und die Brennkammer (9 ) durch eine Trennwand (5) getrennt sind, die auf der Seite der Vergasungskammer (4) den Boden (10) dieser Vergasungskammer und auf der Seite der Brennkammer (9) die obere Innenwand (7) bildet, während die Trennwand (5) von der Düse (2) geführt ist, deren Eintrittsöffnung (1) im Boden der Vergasungskammer (4) und deren Austrittsöffnung (3) in der Innenwand (7) der Brennkammer (9) ausgebildet ist.
