Definitions

  • a pyrolysis gas line is attached to the pyrolysis chamber, preferably at the top thereof, which opens into a reduction zone of the carburettor, advantageously into the oxidation zone of the carburettor.
  • the pyrolysis chamber is surrounded by a heating chamber through which the hot lean gas originating from the gasifier is passed.
  • the lean gas coming from the gasifier with etrwa 700 0 C must be cooled to about 70 0 C to be used in the internal combustion engine, so that there is the advantage that the energy of the lean gas can be used for pyrolysis without much equipment .
  • the feed device is connected to the pyrolysis chamber such that the solid fuels first pass into the pyrolysis chamber, wherein the pyrolysis chamber is preferably arranged above the carburetor. This has the advantage that the solid fuels can stay for a longer time in a hot zone where they can dry and char.
  • the gasification of wood and other solid fuels takes place in different stages.
  • the solid fuels are heated in the pyrolysis chamber to about 400 0 C, so that a charring sets in which the solid fuels also release pyrolysis gases supplied to the carburetor and in the oxidation zone of the carburetor with the product gas of the carburetor at about 1200 0 C. burned, producing CO 2 , water vapor and other gases.
  • These gases are then converted into carbon monoxide and hydrogen by chemical reactions in the reduction zone due to the carbon and high temperatures.
  • the lean gas generated in this case leaves the carburetor then with a temperature of about 700 0 C and is cooled in the heating chamber to the pyrolysis chamber under heating of the solid fuels.
  • the pyrolysis gas formed in the pyrolysis chamber 3 is passed into the gasifier 10, where the pyrolysis gas up to 1200 ° C is heated, whereby impurities are burned. Subsequently, the combustion exhaust gases CO 2 and water vapor in the reduction zone with the heat of combustion are converted to the combustible substances carbon monoxide and hydrogen with the participation of the carbon.
  • the so-called lean gas leaves the carburetor 10 with a temperature of about 700 0 C. Subsequently, the lean gas is passed through a lean gas line 16 in a arranged around the pyrolysis chamber 3 around heating chamber 17, where the lean gas cools under heating of the pyrolysis chamber 3. From the heating chamber 17, the lean gas is passed into a dust separator 15, before this lean gas is then fed to an internal combustion engine not shown here for generating electrical energy.
  • the feeder 2 solid fuels 1 are supplied. This can be done for example via a funnel-shaped reservoir, a conveyor or the like.
  • the solid fuels 1 may have a comparatively high humidity, since the residence time of the solid fuels 1 in the warm zone of the plant is so high that an adequate drying can take place here.
  • the solid fuels 1 located in the cylinder chamber 5 are pushed forward via the feed piston 6 against the resistance of the solid fuels 1 already in the pyrolysis chamber 3, the solid fuels 1 being compressed.
  • the solid fuel 1 pass through the cylinder tube 7 in the pyrolysis 3.
  • the cylinder tube 7 is flanged directly to the pyrolysis chamber 3, wherein the pyrolysis chamber 3 viewed from this flange conically widened to its desired diameter.
