Definitions
- the present invention relates to a furnace for the charring of solids, for example refuse, according to the preamble of claim 1.
- the vortex chamber arrangement consisting of concentric tubes extends over the entire length and width of the treatment chamber.
- the swirl chamber arrangement is such that its interior is connected to it in the region of the end of its exterior facing away from the combustion chamber.
- the heat transfer between the swirl chamber arrangement and the treatment chamber is not optimal and is limited to a certain volume of burner gas.
- the concentric cylindrical arrangement of the vortex chamber arrangement also limits the width of the conveying device for the solids to be smoldered.
- the distance from the outside of the swirl chamber arrangement to the material to be smoldered on the conveyor device is different due to the cylindrical cross section, so that the heat transfer also differs greatly across the width of the conveyor device.
- the object of the present invention is to provide a furnace of the type mentioned at the outset, in which the heat contained in the burner gases can be given off as far as possible to the treatment chamber or the material to be smoldered and over the width of
- Treatment chamber even heating of elongated treatment chambers can be achieved.
- the measures according to the invention ensure that on the one hand a considerably increased burner gas volume flow can be passed through the swirl chamber arrangement and that the capacity can be increased by a corresponding widening of the conveying device in the furnace.
- the oval or elliptical cross section results in a more constant heat transfer into the treatment chamber and thus to the material to be smoldered over a relatively larger width of the conveying device.
- the burner gases are heated and mixed intensively in the relatively short swirl chamber arrangement and can spread out in the flat chamber for a particularly constant heat transfer.

Both the vortex chamber arrangement 51 and the flat chamber 21 extend over essentially the entire width of the treatment chamber 12 or the conveying device 14. In the direction of the longitudinal extent of the treatment chamber 12, the vortex chamber arrangement 51 occupies a smaller length section than the flat chamber 21. the vortex chamber arrangement 51 takes up about 1/4 to 1/3 of the length of the treatment chamber 12, while the remaining length of the treatment chamber 12 is occupied by the flat chamber 21. In addition, the vortex chamber arrangement 51 has approximately three to four times the height of the flat chamber 21. In this respect, the furnace housing 11 is also adapted to these different heights. In other words, the furnace housing 11 has a step-like elevation in the region of the swirl chamber arrangement 51.
- the swirl chamber arrangement 51 is essentially formed from an outer jacket 52 which is oval in cross section and an inner jacket 53 which is also concentric and essentially oval.
- the outer jacket 52 and the inner jacket 53 can have an elliptical shape instead of the oval one and / or can be arranged eccentrically to one another.
- An essentially oval (or elliptical) annular outer space 54 guiding the burner gases is formed between the outer shell 52 and the inner shell 53, and an essentially oval (or elliptical) interior space 55 is formed within the inner shell 53.
- the circumferentially closed outer jacket 52 and the circumferential side closed inner jacket 53 are closed at one axial end with a wall 56.
- This end wall 56 has a cylindrical opening in a radial region, to which an exhaust pipe 57 penetrating the furnace housing 11 connects axially to the outside and is only connected to the interior 55.
- the other axial end of the outer shell 52 and inner shell 53 is also covered by a wall 58, which is provided at two spaced-apart radial areas, each with a cylindrical opening 61 and 62, one of which is in the interior 55 and the other opens into the outer space 54 of the swirl chamber arrangement 51.
- Both cylindrical openings 61 and 62 are connected to the flat chamber 21 on their side facing away from the swirl chamber arrangement 51.
- a burner chamber 63 opens tangentially into the outer jacket 52 near the one wall 56 and is equipped with a burner for oil or gas in a manner not shown.
- the burner chamber 53 has a feed opening 65 for fuel or smoldering gases coming from the treatment chamber 12.
- the tangential arrangement of the supply of the combustion chamber 63 into the outer space 54 of the swirl chamber arrangement 51 lies in the lower region between the oval outer shell 52 and the inner shell 53.
- a burner tube 66 At an axial distance from the burner chamber 63, preferably in a central region between the latter and the other wall 58 opens a burner tube 66, which is also equipped in a manner not shown in detail with a burner for oil or gas.
- the outer space 54 of the swirl chamber arrangement 51 is equipped with a guide helix 71, which begins at an axial distance from the wall 56 in the region of the tangential mouth of the combustion chamber 63 and extends helically up to the other wall 58, so that those flowing in tangentially through the combustion chamber 63 Gases are helically guided in the outer space 54 up to the cylindrical opening 62, the burner gases being guided past the combustion tube 66 for repeated and further heating.
- the outer space 54 is equipped within this helical path 72 with vortex plates 73 projecting inwards from the outer jacket 52 and / or from the inner jacket 53.
- These swirl plates can be so long that they only partially protrude into the web 72, or so long that they extend from the outer jacket 52 to the inner jacket 53 and are each fastened there.
- the swirl plates 73 can be provided in a specific geometric arrangement or also randomly, wherein they can preferably be arranged obliquely or transversely to the direction of flow.
- the interior 55 inside the inner shell 53 is equipped with baffle plates 74 which extend radially and each connect to a radial side wall.
- the individual baffle plates 74 and 75 are alternately arranged in opposite directions at a distance from one another, so that the exhaust gas flow according to FIG.

Both channels 28 and 29 are connected to one another at their end facing away from the swirl chamber arrangement 51. According to FIG.
- the channels 28 and 29 are separated from one another by an essentially flat, upright partition 31.
- the partition wall 31 itself can be designed like a baffle or other measures can be taken for a baffled and thus extended path for the burner gases in the flat chamber 21.
- the passage of the gases through the device 50 is as follows:
- the carbonization gases sucked out of the treatment chamber 12 in the above-mentioned manner are heated in the combustion chamber 63 from a temperature of, for example, 450 ° C. to a temperature of 850 ° C. and as burner gases in the outside space 54 Vortex chamber assembly 51 introduced.
- the burner gases run along the helical path 72, are swirled there and heated again in the region of the burner tube 66 and passed through the opening 62 into one channel 28 of the flat chamber 21.
- the exhaust gases recirculated from the channel 29 of the flat chamber 21 pass through the cylindrical opening 61 into the interior 55 and are swirled along the labyrinthine path 76 and guided in countercurrent to the burner gases in the exterior 54 to the exhaust pipe 57.
- the guidance of the solids to be smoldered on the conveying device 14 takes place from the feed location 19 above the end of the conveying device 14 in the area of the circulation salt 18, so that the material to be smoldered is in the area of the connection of the two channels 28 and 29 of the flat chamber 21 into the furnace housing 11 than occurs at an area of minimum temperature.
- the conveyor 14 arrives with the smoldering material below and along the flat chamber 21 in areas of the treatment chamber 12 provided with a continuously increasing temperature, first below the flat chamber 21 and then below the swirl chamber arrangement 51, at the end of which, viewed in the direction of flow, the maximum temperature has been reached.
- the smoldered solids are expediently returned to the entry end via the deflecting roller 17 below the conveying device 14 and brought there into a transport device in a manner not shown.
