Definitions

  • the invention relates to a thermal afterburning apparatus according to the preamble of claim 1 and a method for operating such according to the preamble of claim 8.

  • the thermal afterburning apparatus is constructed in such a way that, for cleaning, areas of the heat exchanger that are particularly affected by deposits and are further away from the combustion chamber can be exposed to hot clean air.
  • Their temperature is so high that the deposits are detached from the heat exchanger surfaces or oxidized. This requires a temperature of 700 ° C or more.
  • the clean gas at those points of the heat exchanger where deposits occur this temperature no longer.
  • the clean air leaving the combustion chamber in the cleaning mode bypasses a section of the heat exchanger so that it is not cooled down in this section. If it is then introduced into the section of the heat exchanger affected by the deposits, it is therefore still hot enough to be able to remove the deposits.
  • the heating of the debris-affected portion of the heat exchanger in the cleaning mode begins at its warmest end and then proceeds toward the coldest end thereof.
  • the cleaning process is completed when the entire area of the heat exchanger affected by deposits has been brought to the required temperature and the deposits have been removed.

  • a concrete structural embodiment of a thermal afterburning apparatus, with which the mode of operation specified in claim 1 is achieved, is the subject matter of claim 5.
  • the thermal efficiency of the thermal afterburner is to be kept as high as possible, the use of that embodiment, which is mentioned in claim 7 is recommended: the fact that in this embodiment, two sections of the heat exchanger are available, the farther from the combustion chamber are removed, one of these sections can be constantly driven in normal mode.
  • the parallel thereto second section can be cleaned at the same time by a relatively small amount of gas, since a lot of time is available for the cleaning process.
  • the thermal effect of the hot clean air can assist in the removal of deposits and thus achieve a shorter time within which the thermal afterburner must be operated in the cleaning mode.
  • FIG. 1 to 3 a first embodiment of a thermal post-combustion device is shown. This is able to perform a self-cleaning in two different modes of operation, in which from the exhaust air to be cleaned deposits can be removed.
  • the thermal afterburning apparatus is designated overall by the reference numeral 1. It comprises a housing 2, which is composed of a main housing 3, a sub-housing 4 and a walk-under substructure 5.

  • the top of the plenum 7 is formed by a flat separating plate 10, which also serves as the bottom of a cylindrical combustion chamber 11. This is limited in the lateral direction by a cylinder wall 12 and is open at the top.
  • the upper end of the burner 9 is inserted through an axial opening 43 in the separating plate 10 in the combustion chamber 11, so that the flame generated by the burner 9 burns within the combustion chamber 11.
  • the combustion chamber 11 is coaxially surrounded by a deflecting insert 13, which has the shape of a downwardly open cup.
  • the cylinder wall 14 of the deflecting insert 13 terminates at the bottom at a distance from the separating plate 10.
  • two annular spaces namely an inner annular space 16 and an outer annular space 17, the bottom through an annular gap 18 are interconnected.
  • an annular channel 19 or 20 is formed in each case by a radial extension of the cylinder wall 5 of the main housing 3.
  • the outer annular space 17 is separated upwards by a second, planar separating plate 21 from an upper plenum 22.
  • the upper parting plate 21 is guided away in the illustrated embodiment on the deflecting insert 13, could However, as a ring plate to be attached to the bottom of the deflector insert 13.
  • the lower plenum 7 is connected to the upper plenum 22 by a plurality of axially parallel lying on an imaginary cylinder jacket surface heat exchanger tubes 23 which pass through the outer annular space 17 and form a primary heat exchanger 50 a.
  • the heat exchanger tubes 23 are provided with a plurality of surface structures 24 over most of their axial extent, with which the effective surface of the heat exchanger tubes 23 can be increased in a manner not of interest here.
  • the interior of the secondary housing 4 is bounded by a cylinder wall 25, a lower planar separating plate 26 and an upper planar separating plate 27. It has a lower, coaxial with the cylinder wall 25 extending inlet port 28 for the exhaust air to be cleaned and at the top and bottom end of a respective radially outflow outlet port 29 and 30 for clean air.
  • the interior of the secondary housing 4 is penetrated by a plurality of heat exchanger tubes 31, which together form a preheat exchanger 50 b and connects the inlet nozzle 28 with the upper plenum 22. This extends from the main housing 3 to the secondary housing 4.
  • the heat exchanger tubes 31 of the preheat exchanger 50b are provided in the same way with recesses 32 as the heat exchanger tubes 23 of the primary heat exchanger 50a within the main housing. 3
  • the annular channels 19, 20 of the main housing 3 are each connected by a connecting line 33 and 34 with the lower and upper end portion of the inner space of the secondary housing 4 connected.
  • the two connecting lines 33, 34 in turn communicate via a further connecting line 35, which runs substantially parallel to the axis.

  • Further flaps 39, 40 are located in the two outlet ports 29, 30 for clean air. All flaps 36 to 40 can be brought by hand or motor into all positions between a full closed position and a full open position.
  • thermal post-combustion device 1 functions as follows.
  • the exhaust air to be cleaned is supplied via the inlet port 28 and flows through the preheat exchanger 50b formed by the heat exchanger tubes 31, thus entering the upper plenum 22, flows from there through the primary heat exchanger 50a formed by the heat exchanger tubes 23 in the main housing 3 down into the lower plenum 7. From there, the exhaust air is blown through the axial opening in the lower separating plate 10 into the combustion chamber 11; the entrained impurities begin to oxidize there at the temperature generated by the burner 9.
  • the hot air flows over the upper edge of the cylinder wall 12 of the combustion chamber 11 into the inner annular space 16, within this downward and passes through the gap 18.
  • the now called clean air hot air passes from there into the outer annular space 17 and flows around the heat exchanger tubes located there 23 of the primary heat exchanger 50a on their way up into the upper annular channel 20. From the upper annular channel 20, the hot clean air flows past the open flap 38 through the upper connecting line 34 in the upper end portion of the interior of the sub-housing 4, from there on the outside of the heat exchanger tubes 31 to the lower outlet port 29, where it leaves the thermal afterburning device 1 with the door open 39 for further use and disposal.
  • FIG. differs from the normal operating mode shown in Figure 1 only by the position of different flaps: Now, the flap 38, which connects the main housing 3 to the sub-housing 4 in the upper region, closed; Similarly, the lower outlet port 29 is blocked by a corresponding position of the flap 39. Instead, the connection between the main housing 3 and the sub-housing 4 via the lower connecting line 33 by opening the flap 36 is free; the valve 37 lying in the connecting line 35 remains closed.
  • the deposits located on the inner lateral surface of the heat exchanger tubes 31 can be loosened, possibly oxidized and flushed out with the air flowing through them.
  • Additives, for example catalysts, which are introduced into the exhaust air can assist this process.
  • the operation of the thermal afterburning apparatus 1 does not have to be interrupted.
  • the exhaust air is still cleaned, but leaves the thermal post-combustion device 1 with a slightly higher temperature, so that therefore the thermal efficiency during the first cleaning mode is slightly reduced.
  • This can be accepted as the times in which the operation in cleaning mode is required, are relatively short.
  • the cleaning mode can be discontinued as soon as the heat exchanger tubes 31 have reached the required temperature from bottom to top over their entire axial length and the contaminants have detached.
  • the thermal afterburning apparatus 1 can be operated in a second cleaning mode, in which the flaps are placed in the manner shown in FIG. 3:
  • the flap 38 in the upper connecting line 34 between the main housing 3 and the sub-housing 4 remains closed. Locked is now the upper outlet port 30 of the secondary housing 4 by appropriate closing of the flap 40, while the lower outlet port 29 is released by opening the flap 39.
  • the flap 36 in the lower connecting line 33 is moved to the closed position; instead, the flap 37 is opened in the connecting line 35.
  • the only difference between the second cleaning mode shown in Figure 3 compared to the first cleaning mode shown in Figure 2 is that in the former the hot clean air is introduced into the upper region of the interior of the secondary housing 4 and in this countercurrent to the heat exchanger tubes 31 flowing through Exhaust air flows. In this way, the upper regions of the heat exchanger tubes 31 can be heated particularly well.
  • the two cleaning modes of Figures 2 and 3 can be operated alternately clocked, so that alternately preferably the lower and then again preferably the upper portions of the heat exchanger tubes are freed of deposits.
  • FIGS. 4 and 5 The construction of the second exemplary embodiment of a thermal afterburning apparatus shown in FIGS. 4 and 5 largely corresponds to that embodiment described above with reference to FIGS. 1 to 3. Corresponding parts are therefore identified by the same reference numeral plus 100.
  • the flaps 136, 137, 138 are adjusted, as will be described below.

  • the main part of the preheat exchanger 150 b which is formed by the heat exchanger tubes 131
  • bypassed the clean air leaves the thermal post-combustion device 101 via the outlet port 129 thus at a relatively high temperature; the thermal post-combustion device 101 operates for a short time with a deteriorated thermal efficiency.
  • this flap position essentially only the areas of the heat exchanger tubes 131 located below the lower annular channel 141 are cleaned. However, this is sufficient in many cases, since there is the greatest risk of deposition of contaminants due to the prevailing temperature conditions.
  • the thermal afterburning apparatus 101 of FIGS. 4 and 5 can also be operated in a mixing operation between normal and cleaning modes, as shown in FIG 5 is shown.
  • the flaps 136, 137, 138 are in an intermediate position between the full open and full closed positions.
  • the self-cleaning effect can be adjusted: the more the flap 138 is closed in the upper connecting line 134, the more hot clean gases bypass the primary heat exchanger 150a formed by the heat exchanger tubes 123 and can therefore be used for cleaning purposes.
  • the position of the various flaps 136, 137, 138 during operation of the thermal afterburning apparatus 101 may also be changed continuously, as required by the particular circumstances.
  • An interruption of operation of the thermal afterburning apparatus 101 for cleaning the preheat exchanger 150b is required as little as in the embodiment of Figures 1 to 3; the loss of thermal efficiency, which is inevitable during the cleaning operation, in contrast, is readily acceptable.
  • a preheat exchanger 250b is associated with the primary heat exchanger 250a; Rather, two preheat exchangers 250b, 250b 'are provided, which are in principle laid parallel to each other and, as will be described in detail below, can be operated alternately in different operating modes.

Unlike in the embodiment of Figures 1 and 2, however, there is no flap in that of Figures 6 and 7 in the upper connecting line 234.
  • the interiors of the two sub-housings 204 and 204 ' are each traversed by a plurality of axially parallel heat exchanger tubes 231, 231' extending from an inlet port 228, 228 'of the respective preheat exchanger 250b, 250b' to the upper plenum 222, in the embodiment of FIGS 6 and 7 over the first sub-housing 204 across the second sub-housing 204 'is guided.
  • the two inlet ports 228, 228 'each include a motorized flap 282, 282' and are connected to a main inlet port 280, via the exhaust air to be cleaned is supplied to the thermal afterburning device 201.
  • the two outlets 229, 229 'of the two sub-housings 204, 204' are connected to a main outlet port 281, via which the clean air is discharged.
  • FIG. This shows the position of the various flaps in an operating mode in which the second preheat exchanger 250b 'operates in normal mode and the first preheat exchanger 250b is idle.
  • all the valves 236, 239 and 282 associated with the first preheat exchanger 250b are closed.
  • the flap 236 'leading to the lower end region of the interior of the second secondary housing 204' is likewise closed, while the flaps 282 'and 239' are open.
  • the exhaust air to be purified flows via the inlet port 228 'into the heat exchanger tubes 231' of the second preheat exchanger 250b ', via the upper plenum 222, through the heat exchanger tubes 223 of the primary heat exchanger 250a, through the lower plenum 207 into the combustion chamber 211 where the combustion of the contaminants is introduced, via the annular spaces 216, 217 on the outer surfaces of the heat exchanger tubes 223 along and then via the upper connecting line 234 into the interior of the second secondary housing 204 '. From there, the clean gas flows to the outer surfaces of the heat exchanger tubes 231 'of the second Preheat exchanger 250b 'over the open flap 239' to the main outlet 281.
  • the flap positions of the two preheat exchangers 250b and 250b' are simply exchanged analogously. In principle, it is also possible to drive both preheat exchangers 250b and 250b 'under the same flap position simultaneously in normal mode.
  • the flap 282 located in the inlet port 228 of the first preheat exchanger 250b is slightly opened, as well as the flap 236 determining the supply of clean air from the main housing 203. This has the following consequences for the gas flows:
  • the exhaust air is the second preheat exchanger 250b 'fed, but passes, depending on the degree of opening of the flap 282, and a certain part of the exhaust air in the preheat exchange 250b.
  • the part of the exhaust air diverted into the preheat exchanger 250b should be kept as small as possible in order to keep the overall efficiency of the thermal afterburning device 201 as high as possible. While the flow paths for that part of the exhaust air which flows through the second preheat exchanger 250b 'remain unchanged, the flow conditions change in the first preheat exchanger 250b as follows:
  • flap 236 Due to the partially opened flap 236 enters a corresponding amount of clean air at a temperature of about 700 ° C in the lower end of the interior of the first sub-housing 204 a. This flows past the outer surfaces of the heat exchanger tubes 231 of the first preheat exchanger 250b and heats them. The interior of these heat exchanger tubes 231 is simultaneously flowed through by the exhaust air which passes through the flap 282 in the inlet pipe 228. These flows can be maintained for a very long time, since the second preheat exchanger 250b 'continues to operate in normal mode.
  • the exhaust air flowing through the heat exchanger tubes 231 of the first preheat exchanger 250b and carrying the scorched deposits is mixed in the upper plenum 222 with those exhaust air coming from the second preheat exchanger 250b 'and is then supplied with it to the combustion in the combustion chamber 211.
  • the third embodiment of the thermal afterburning apparatus 201 allows extremely variable operation depending on the extent to which the flaps 236, 236 ', 239, 239' and 282, 282 'are opened, which determine the gas flows through the two preheat exchangers 250b, 250b'.
