Definitions

  • the invention relates to a wood gas generator according to the preamble of claim 1.
  • the formation of the gasification stove is defined in detail, which follows the well-known construction principle used by the German company IMBERT.
  • a so-called nozzle ring is of importance, which is coaxially installed in the vertical cylindrical gasification shaft and constricts it.
  • wood gas generators have the disadvantage that the gas produced contains a lot of tar, which damage the engine and the environment. There are also other pollutants in the gas.
  • the invention has for its object to avoid these pollutants to a significant extent. This object is achieved according to the invention in a wood gas generator of the type described in the introduction by the characterizing features of claim 1.
  • a gas ring channel is then provided in the nozzle ring, in which the gas obtained is subjected to a second combustion.
  • the nozzle ring in particular its upper bead-starting section, lies in the hottest zone and reaches a temperature of approx. 1,000 ° C.
  • the gas normally from the annular space which surrounds the lower annular jacket section of the nozzle ring, is withdrawn to the outside, according to the invention the gas is first allowed to flow through the annular channel in order to thereby burn at least the tar fractions and possibly to add further pollutants to the solid combustion residues.
  • a further development of the invention consists in the fact that a possibility is also created that gas, as known, is taken directly from the gasification zone and a switching device is provided with which the outlet opening of the gas ring channel can optionally be closed and the immediate removal opening can be opened and vice versa. Finally, it is expedient to design the switching device in such a way that both gas paths can be operated with optionally different flow cross sections and the gas streams can be mixed.
  • the lower part of the wood gas generator shown comprises a container 1, which is surrounded by heat-insulating material and has a rotating grate 2 above the floor. At a distance above this is a nozzle ring 3 connected to the container wall, which is divided into an upper bead-like section 4 and a ring jacket section 5 projecting freely downwards. There is a over the nozzle ring circumferential intake air duct 6 is provided, which is fed through an intake air nozzle 7 and emits the air via individual nozzles 8 into the gasification zone.
  • the nozzle ring 3 contains a gas ring channel 11 which is separated at one point by a transverse wall 12 so that the gas ring channel has a beginning and an end.
  • the beginning is connected to the annular space 10 via an inlet opening 13 and the end opens outwards via an outlet pipe 14.
