Definitions
- the invention relates to a wood gas generator according to the Generic term of claim 1.
- Gasification focus defined in detail, the known, construction principle followed by the German company IMBERT.
- a so-called nozzle ring is important, which in the vertical cylindrical gasification shaft installed coaxially is and constricts it.
- wood gas generators have the disadvantage that the generated gas contains a lot of tar, which the engine and harm the environment. There are also others Contain pollutants in the gas.
- the invention is based on the object to provide a wood gasifier that improved Afterburning enabled and at these pollutants to a large extent be avoided. This task will in the case of a wood gas generator of the type described in the introduction according to the invention by the characterizing features of Claim 1 solved.
- a gas ring channel is then provided in the nozzle ring, in which is the gas obtained from a second combustion is subjected.
- the nozzle ring in particular its upper beaded section lies in the hottest zone and reaches a temperature of approx. 1,000 ° C.
- the gas is still left according to the invention flow through the ring channel to thereby at least the Burn tar parts and possibly even more Accumulate pollutants on the solid combustion residues.
- a further development of the invention is that a Possibility is created that gas as known immediately from the gasification zone and a Switching device to provide, with which the Close the outlet opening of the gas ring channel and the immediate opening opening and vice versa. Finally, it is expedient to switch the device in this way train that both gas paths with optional operated different flow cross sections and the Gas flows can be mixed.
- the lower part of the wood gas generator shown comprises one with insulating material surrounding container 1, the over the floor has a rotating grate 2. At a distance above this one is connected to the container wall Nozzle ring 3, which is in an upper bead-like Section 4 and one protruding freely downwards Ring jacket section 5 is divided. There is a over the nozzle ring circumferential intake air duct 6 provided by a Intake air connector 7 is fed and the air over individual Dispenses nozzles 8 into the gasification zone.
- the nozzle ring 3 contains a gas ring channel 11 at is separated by a transverse wall 12 so that the gas ring channel has a beginning and an end.
- the beginning is in via an inlet opening 13 with the annular space 10 in Connection and the end opens out via an outlet pipe 14 Outside.

Claims (3)
- Holzgaserzeuger mit einem im Gaserzeuger-Unterteil angeordneten Düsenring, der mit seinem oberen wulstartigen Abschnitt den Vergasungsraum horizontal einschnürt und unten einen frei nach unten abstehenden Ringmantelabschnitt aufweist, der mit der Vergasungsraum-Außenwand einen Ringraum bildet, aus dem das Gas abgezogen wird, wobei die Ansaugluft oberhalb des Düsenrings zugeführt wird, dadurch gekennzeichnet, daß in dem Düsenring (3) ein nahezu 360° umlaufender Gasringkanal (11) nur in dessen wulstartigem Abschnitt ausgebildet ist, der am Anfang über eine Einlaßöffnung (13) mit dem Ringraum (10) in Verbindung steht und dessen Auslaßöffnung (14) nach außen in einen Abzugskanal (17) mündet.
- Holzgaserzeuger nach Anspruch 1, dadurch gekennzeichnet, daß eine Umschalteinrichtung (15) vorgesehen ist, mit der sich wahlweise die Auslaßöffnung (14) des Gasringkanals schließen und eine unmittelbare Auslaßöffnung (9) des Ringraumes öffnen und mit dem Abzugskanal (17) verbinden läßt und umgekehrt.
- Holzgaserzeuger nach Anspruch 2, dadurch gekennzeichnet, daß beide Gaswege mit wahlweise unterschiedlichen Strömungsquerschnitten betrieben und die Gasströme gemischt werden können.
