Definitions

  • the British patent GB 1,358,743 is concerned with the oxidizing or afterburning apparatus of exhaust gas, which apparatus is particularly determinded for combustion engines.
  • a turbulence of mixing chamber widening towards the centre belongs to this, and the exhaust gases are led to this chamber tangentially through one or more nozzles and are brought in this way to revolving motion.
  • the additional air is led through the air opening at the axis of the mixing chamber.
  • the mixture of gas and air is led out from the mixing chamber through the opening on the opposite side of the air opening to the ball-shaped combustion chamber.
  • the ignition devices have been preferably placed to this in order to effect the burning of the gas.
  • OMPI Influenced through the pressure, difference between the outer air pressure or a pressure of a corresponding air or oxygen container and the mentioned lowpressure field air absorbs through the air tube 2 to the centre of the turbulence axially advancing in the vicinity of the mantle of the intermediate chamber and is effectively mixed with the turbulence.
  • the temperature of the smoke gas turbulence is most often sufficiently high in order to bring forth a selfignation, when on bursting of the gas turbulence widening to the exhaust chamber 4, it at the same time ignites.
  • the gas turbulence advancing along the outer wall 41 in the exhaust chamber further absorbs air from the second air channel 14, it widenes and is led through the exhaust chamber 4 and the outlet channel 5 to the combustion chamber 6, where the final burning takes place.
  • the deposits remove through the exhaust tube or- the corresponding outlet channel out.
  • Air can be led either through a hollow axis 19 or through the channels in the centre of the combustion space or through the nozzle 2 to the exhaust chambers.
  • the chamber spaces 1, 4 have been placed to a distance from each other and the diameter of the first one is smaller than that of the next one etc.
  • Th angles of ascent of the steering baffles 12 are preferably arranged in a way that the angle of ascent connected with the latter chamber is bigger than the angle of ascent connected with the former chamber.
  • Fig. 7 shows an embodiment of the invention where the chambers 1 , 31 , 4 and the air channel 2 have been arranged in successionion in a way that they form a symmetrical system.
  • the inner back and forth pressure wave of the exhaust pipes generates a lowpressure and a suction in the chamber space independent of the direction of the pressure wave in the exhaust pipes.
