Definitions

  • the invention relates to a burner for heating air according to the preamble of patent claim 1.
  • the tubes provided with gas outlet openings consist of straight tube pieces to which the possibly corrugated, wedge-shaped widening mixing plates are fastened, the end-side, V-shaped gaps being closed by end plates, one of which is provided with the ignition electrode.
  • manually adjustable air baffles are provided in the air duct, with which the amount of fresh air passing through the mixing plates can be controlled.
  • the known burners work well with a sufficiently large parallel air flow at higher output, that is to say at higher temperatures.
  • the gas burns only on the gas supply side of the tube, on which the ignition electrode is also arranged.
  • the disadvantage therefore arises that if the gas is incompletely burned, an uneven temperature profile arises.
  • the one-sided combustion of the gas develops even more when the pipes provided with the gas outlet openings and the mixing plates are assembled into L, T or H-shaped burners because the flames are difficult to jump over the corners formed by the burner. So there are uneven, torn flame patterns that prevent optimal combustion.
  • the object of the invention is therefore to provide a burner of the type specified at the outset, which ensures even combustion of the gas over its length even when the gas supply is reduced.
  • the burner according to the invention can be arranged in the duct through which the air flows so that uniform flow profiles result which promote combustion.
  • the amount of air flowing through the mixing plates can be controlled in a simple manner by means of the conical air baffle that can be displaced in the axial direction.
  • the amount of air flowing through the outer annular mixing plate depends on the size of the annular gap between the edge of this annular mixing plate and the air baffle, which can be changed in the desired manner by moving the air baffle.
  • the tube has at least two concentric channels which are separated from one another by intermediate walls in the region of the gas supply and are provided with a gas overflow line connecting the channels on the side of the first partition opposite the gas supply.
  • This series connection of concentric, circular channels ensures that gas flows through the subsequent channel only when the first channel is completely filled with gas. Since a sufficient amount of gas flows out of the gas outlet openings of the first channel even in the partial power range, a uniform circular flame results, which ensures complete combustion and a uniform temperature profile. At higher power, the gas that has not already escaped through the gas outlet openings of the first ring channel flows into the ring channel or the downstream ring channels, so that higher air temperatures can be achieved without a significant change in the temperature profile.
  • the gas emerging from the ring channels following the first ring channel increases the total amount of gas coming to the combustion, a complete combustion of the gas being ensured due to the annular flame already generated by the first channel.
  • annular tube which is divided into concentric ring channels by one or more circumferential partition walls, two or more concentric tubes can also be provided.
  • An annular burner 2 the axis of which coincides with the axis of the air duct, is fastened in a tubular air duct 1 through which air to be heated flows, via holding pieces (not shown).
  • the burner 2 consists of an annular tube which is divided into two bowl-shaped bodies 3, 4 in its central plane.
  • the bowl-shaped bodies 3, 4 are provided with annular partition walls or webs 7, 8 provided that divide the burner tube into channels 9, 10 which are concentric with one another.
  • the tube shell 4 is provided on both sides of the web 7 with gas outlet openings 11, 12 which are arranged on circles which are concentric with one another.
  • the nozzle openings formed by the gas outlet openings 11, 12 open on the end face of an annular web connected to the tubular shell 4, on the cylindrical inner and outer sides of which funnel-shaped mixing plates 13, 14 are fastened.
  • the mixing plates 13, 14 are provided with through openings 15 of different sizes for the air in the manner shown in FIG. 3.
  • the channels 9, 10 are provided on the left next to a connecting piece 16 for the gas with transverse walls 17, 18.
  • the channels 9, 10 are connected to one another to the left of the transverse walls 17, 18 by a passage opening 19.
  • the gas supplied through the pipe socket 16 thus initially flows in the direction of the arrows through the outer channel 9 and only enters the inner channel through the passage opening 19 if it does not completely flow through the outer channel 9 with the flow through the outer channel 9 connected gas outlet openings 12 has emerged.
  • an air baffle plate 20 that narrows conically in the direction of flow is provided, which is displaceably guided in the axial direction on the inner wall of the air duct 1.
  • the air baffle 20 is shown in solid lines in an advanced position in which there is a relatively large annular gap between it and the outer edge of the outer mixing plate 13, so that the majority of the air can flow past the outer mixing plate 13 without passing through it To pass holes.
  • the air baffle 20 is shown in dashed lines in a retracted position, in which there is only a relatively narrow annular gap between it and the outer edge of the mixing plate 13, so that a larger part of the supplied air flows through the mixing plates.
  • An ignition gas tube 22 is arranged in the outer mixing plate 13 in front of the gas outlet openings 11, 12 arranged on concentric rings.
  • a sensor 23 is provided in the inner mixing plate 14 for ionization monitoring.
  • the burner tube consists of two shell-shaped halves which only delimit an annular channel into which the pipe socket opens.
  • the gas outlet openings are on the other, shell-shaped half, not shown.
