Definitions

  • thermal post-combustion devices such as they are currently on the market, have heat exchanger tubes with a smooth surface. This is the efficiency constructed of these heat exchanger tubes Heat exchanger essentially fixed. The extent, in which the thermal post-combustion device leaving gases deprived of heat and in the the contaminated gases in front of the combustion chamber the heat is fed, is for sure. It exists however, depending on the thermal afterburner Downstream facility, quite the desire according to different outlet temperatures of the purified Gas. So far, this was the heat exchanger of used in individual cases thermal afterburners thereby adapted in their capacity that their Length was changed. However, that meant a lot profound intervention in the basic construction the thermal afterburners, so that at the different members of this familiar sentence of thermal afterburners in part very different building components are used had.
  • the object of the present invention is to provide a sentence of thermal post-combustion devices, its individual members cheaper to produce are.
  • the heat exchanger tubes not with smooth surface but with elevations and / or recesses provided on this lateral surface are an extra degree of freedom in the setting the desired heat exchanger efficiency Achieved:
  • the number and / or the height of the surveys or Depth of the wells at these different Members is chosen differently.
  • the housing should have a removable lid, in particular, to the heat exchanger tubes in the Cleaning access to get.
  • thermal post-combustion device comprises a circular in plan view housing 2 with a laterally disposed inlet pipe 3 for contamination containing exhaust air and a this inlet port 3 diametrically opposite, but something higher arranged outlet 4 for purified Air.
  • the inlet pipe 3 communicates with a lower one Air distribution chamber 5, the down through a heat-insulated floor 6 and upwards for a through the bottom 8 of a cup-shaped insulating and deflecting insert 7 and on the other by a the floor. 8 surrounding annular tube sheet 9 is limited.
  • annular tube bottom 9 are the lower ends of a Variety axially parallel heat exchanger tubes 10 attached, which all have the same radial distance from the axis of the housing 2 own.
  • the interiors of the heat exchanger tubes 10 communicate at their lower end with the air distribution space 5.
  • the upper ends of the heat exchanger tubes 10 are in one attached to upper heat exchanger bottom 11, which is except for a near-axis passage opening 12 over the entire cross section of the housing 2 extends.
  • the housing 2 comprises a dome-like cover 2a, on the circular cross-section portion 2b of the housing 2 is placed tightly but releasably.
  • a Burner 14 introduced into the interior of the housing 2, the extends into the opening 12 of the upper tube sheet 11.
  • the burner 14 is not shown above Lines supplied with fuel, such as gas.
  • the lid 2a and the upper tube sheet 11 define together an upper distribution space 15, with the upper Ends of the interiors of the heat exchanger tubes 10 communicates.
  • the heat exchanger tubes 10 used here are not provided with a smooth lateral surface; rather, the Heat exchanger tubes 10 in a lower axial region a plurality of recesses 18 through which the effective heat exchange surface of the heat exchanger tubes 10 is increased compared to those with smooth outer surface.
  • the effective heat exchanger surface is thus not only dependent the radius and the length of the heat exchanger tubes 10 but also from the density distribution of the recesses 18 and their depth and the length of the axial region, are provided on the recesses 18, from.
  • the annular space 25 between the housing 2 and the insulating and deflecting insert 7 is by two Annular spaces 26, 27 radially expanded.
  • the first annulus 26 is located at the lower end of the gap 25th and is via a channel 28 with the outlet 4 in connection.
  • In the channel 28 is an adjustable Throttle 30.
  • the second annulus 27 is located something underneath half the height of the space 25. He is via a channel 29, in which an adjustable throttle 31 is connected to the outlet 4.
  • the thermal afterburning apparatus shown in the drawing 1 works as follows:
  • the exhaust air to be cleaned is through the inlet pipe 3 passed into the lower distribution space 5. From there flows they enter the lower ends of the heat exchanger tubes 10, flows through this up to the upper distribution space 15, from where they, if necessary by air blades 19 of the Burner 14 swirls, in the inside of the combustion chamber housing 16 located combustion chamber 20 occurs. There will heated to a temperature with the aid of the burner 14, in which the contaminants burn.
  • the efficiency of the heat exchanger tubes 10th formed heat exchanger obviously depends on the Heat exchanger surface and, as noted above, from the number of heat exchanger tubes 10, whose diameter and the number and depth of the recesses 18. are Once this data is established, the heat exchanger efficiency is also certainly.
  • the inflowing over the inlet port 3 Exhaust air is therefore when passing through the Heat exchanger tubes 10 in a very specific proportions heated. Accordingly, the temperature of the thermal drops Afterburning device 1 via the outlet 4 leaving air also on a whole certain value.
  • the burner 14 must leave the heat exchanger tubes 10 Exhaust air so much energy that their Temperature on the combustion chamber 20 for the combustion of Impurities required temperature is brought.
  • the manufacturer can get a whole "set" of offer thermal afterburning devices 1, which can be largely identical and therefore rational and can be produced inexpensively, nevertheless for different purposes, the different outlet temperatures of the purified Require air, are suitable.
  • the thermal afterburner 1 For each member of this sentence can be adjusted by the By-Pass, passing through the upper annulus 27, the canal 29 and the throttle valve 31 is formed, the outlet temperature to be changed. To increase the outlet temperature the upper Dosselklappe 31 is slightly opened and the lower throttle valve 30 is closed accordingly. With Help the throttle valves 30, 31, the thermal afterburner 1 also to some extent be adapted to different flow rates.
