Definitions
- the invention relates to a thermal afterburning apparatus according to the preamble of claim 1 and to a method for operating such according to the preamble of claim 6.
- Thermal afterburners are standard ⁇ used in the industry for exhaust air afterburning. At the same time, they serve to obtain thermal energy which is trapped in the contaminants entrained in the exhaust air.
- thermal post-combustion devices of the type mentioned above, it is only possible to dispose of air containing sticky residues, since deposits form on the colder areas of the heat exchanger surfaces, which clog the heat exchanger over the course of time or at least reduce its efficiency. Therefore, at regular intervals, it is necessary to carry out repeated operations and expensive cleaning work.
- the object of the present invention is therefore to provide a thermal afterburning apparatus of the kind specified in the preamble of claim 1 and a method for operating such, with which the exhaust air can be cleaned substantially without interrupting operation, the sticky residues, in particular pitch vapors , contains.
- This object is achieved, as far as the thermal afterburning apparatus itself is concerned, by the invention disclosed in claim 1.
- the thermal afterburning apparatus is constructed in such a way that hot areas of the heat exchanger which are particularly affected by deposits and which 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.
- a temperature of 700 0 C or more is required.
- 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 processing of the exhaust air is therefore continuously continued even in the cleaning mode of the thermal afterburning apparatus; the only difference is that during the relatively short times a cleaning mode is run, a somewhat lower efficiency of the heat exchanger is accepted.
- the heating of the section of the heat exchanger affected by deposits in the cleaning mode begins at its warmest end and then proceeds in the direction of its coldest end.
- the Cleaning process is completed when the entire affected by deposits area of the heat exchanger is brought to the required temperature and the Ablage ⁇ ments are removed.
- the section of the heat exchanger affected by the deposits is heated from its cold end. As a result, deposits closer to this cold end are reached faster than in the embodiment of claim 2.
- embodiment which is mentioned in claim 4 In this can be alternately or optionally heat affected by deposits portion of the heat exchanger from the warm or from the cold end ago. In this way, the shortest cleaning times can be achieved.
- a concrete structural embodiment of a thermal after-combustion device, with which the mode of operation specified in claim 1 is achieved, is the subject matter of claim 5.
- the thermal effect of the hot clean air can assist in the separation of deposits and in this way achieve a shorter time within which the thermal afterburning apparatus operates in the cleaning mode must become.

- FIG. 6 shows a vertical section through a third embodiment of a thermal afterburning device in the normal mode
- FIG. 7 shows the thermal afterburning apparatus of FIG. 6 in a mixed mode of operation.
- 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 secondary housing 4 and a walk-under substructure 5.
- the walk-under substructure 5 is arranged coaxially below the main housing 3 and carries the main housing
- the ceiling 6 of the base 5 is curved downwards - S -
- a burner 9 is passed.
- the components required for operation of the burner 9 and not specifically shown in the drawing, in particular the electrical control and supply lines and the fuel supply lines, are accommodated in the substructure 5 and can be easily maintained there.
- the top of the plenum 7 is formed by a flat Trenn ⁇ sheet 10, which also serves as the bottom of a cylindrical combustion chamber 11. This is delimited 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 deflection insert 13, which has the shape of a downwardly open
- the cylinder wall 14 of the Umlenkein ⁇ rate 13 ends below at a distance from the partition plate 10. In this way arise between the cylinder wall 12, the combustion chamber 11 and the cylinder wall 15 of the main housing 3, two annular spaces, namely an inner
- 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 separating plate 21 is guided away over the deflecting insert 13 in the exemplary embodiment shown 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 on a imaginary Zylin ⁇ dermantel construction lying 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 as well as at the upper and lower end region in each case a radially-led outlet nozzle 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 with depressions 32 in the same way as the heat exchanger tube 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.
- a first flap 36 In the lower connecting line 33 between the Hauptge ⁇ housing 3 and the sub-housing 4 is a first flap 36 and that in the section which lies between the mouth of the connecting line 35 and the sub-housing 4.
- the flow through the connection line 35 can be controlled by a second flap 37; a third flap 38 is finally in the upper connecting line 34 and that between the upper annular channel 20 of the main housing 3 and the discharge point of the connecting line 35.
- 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.
- the thermal afterburning apparatus 1 described above functions as follows:
- 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.
- the hot clean air flows past the open flap 38 through the upper connecting line 34 in the upper end region of the interior of the secondary housing 4, from there on the outside of the heat exchanger tubes 31 over to the lower outlet port 29, where it leaves the thermal Nach ⁇ combustion device 1 with open flap 39 for further use and disposal.
- thermal afterburning device 1 In this normal operation of the thermal afterburning device 1, relatively cold exhaust gas passes via the inlet port 28 into the relatively cool heat exchanger tubes 31, the temperature of which increases from bottom to top. Depending on the impurities entrained by the exhaust air, these may deposit on the inner walls of the heat exchanger tubes 31 and would block the passage through the heat exchanger tube 31 if countermeasures were not taken. For this purpose, it is possible to operate the described thermal post-combustion device 1 in two different cleaning modes.
- 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 with the sub-housing 4 in the upper area, ge 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 flap 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 released, 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 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 stopped as soon as the heat exchanger tubes 31 has reached the required temperature from bottom to top over its entire axial length and the contaminants have detached.
- the thermal afterburning device 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 secondary housing 4 remains striglos ⁇ sen. 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 FIG. 3 and the first cleaning mode shown in FIG. 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 tube 31 flowing exhaust air flows. In this way, the upper regions of the heat exchanger tube 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.
- the construction of the second exemplary embodiment of a thermal afterburning device illustrated in FIGS. 4 and 5 largely corresponds to that embodiment which was described above with reference to FIGS. 1 to 3. Corresponding parts are therefore identified by the same reference sign plus 100.
- thermal post-combustion device 101 of FIGS. 4 and 5 in normal operation coincides completely with that of the normal operation of the first embodiment (see FIG. 1), so that reference may be made to the above explanations.
- the flaps 136, 137, 138 are adjusted, as will be described below. To explain, let's first assume that the flap
- both the primary heat exchanger 150a, which is formed by the heat exchanger tubes 123, and the main part of the preheat exchanger 150b, which is formed by the heat exchanger tubes 131, are bypassed by the clean air.
- 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 works briefly with a reduced thermal efficiency.
- this flap position essentially only the areas of the heat exchanger tubes 131 lying below the lower annular channel 141 are cleaned. However, in many cases this is sufficient because of the prevailing temperature conditions greatest risk of deposition of contaminants exists.
- the thermal afterburning apparatus 101 of FIGS. 4 and 5 can also be operated in a mixed operation between normal and cleaning mode, as shown in FIG. gur 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 stronger the
- Damper 138 is closed in the upper connecting line 134, the more hot clean gases avoid the primary heat exchanger 150a formed by the heat exchanger tubes 123 and can therefore be used for cleaning purposes.
- the position of the flaps 136 and 137 determines which portions of the clean clean air branched off for cleaning purposes are respectively supplied to the upper region of the interior of the secondary housing 104 and the lower region of the interior of the secondary housing 104.
- the more hot clean gas is supplied to the upper region the faster is reached in the upper region of the heat exchanger tubes 131 that temperature which is required there to detach the impurities from the inner circumferential surfaces of the heat exchanger tubes 131.
- the more hot gases are supplied to the upper region of the interior of the Maugeophu ⁇ ses 104, the greater theides ⁇ degree of the heat exchanger tubes 131 formed by the preheat exchanger 150 b.
- the position of the various flaps 136, 137, 138 during operation of the thermal afterburning device 101 can also be changed continuously, as required by the respective conditions.
- An operation interruption of the thermal afterburning apparatus 101 for cleaning the preheat exchanger 150b is required as little as in the embodiment of Figs. 1 to 3; the loss of the thermal efficiency, which is unavoidable during the cleaning operation, is readily acceptable.
- the efficiency of the thermal afterburning apparatus decreases during the cleaning mode. Therefore, the aim is to keep the system as short as possible in saws ⁇ mode.
- FIGS. 6 and 7 This Aus ⁇ guide corresponds largely to that of Figures 1 and 2, so that reference is made to the above description of these figures and below essentially the differences between the embodiment of Figures 1 and those of Figures 6 and 7 will be described. Corresponding parts of the exemplary embodiment of FIGS. 6 and 7 are identified by the same reference numerals as in FIGS. 1 and 2 plus 200.
- FIGS. 6 and 7 Unchanged from the exemplary embodiment of FIGS. 1 and 2, in FIGS. 6 and 7 the main housing 203, which is supported by a substructure 205, the lower plenum 207, the burner 209, which generates a flame in a cylindrical combustion chamber 211 Baffle 213, the upper plenum 222 and the lower plenum 207 to the upper plenum 222 connecting heat exchanger tubes 223, which form a primary heat exchanger 250 a.
- the main housing 203 which is supported by a substructure 205, the lower plenum 207, the burner 209, which generates a flame in a cylindrical combustion chamber 211 Baffle 213, the upper plenum 222 and the lower plenum 207 to the upper plenum 222 connecting heat exchanger tubes 223, which form a primary heat exchanger 250 a.
- preheating exchanger 250b not only a preheating exchanger 250b is assigned to the primary heat exchanger 250a; Rather, two preheating sheaves 250b, 250b 1 are provided, which in principle are arranged parallel to one another and, as will be described in detail below, can be operated alternately in different operating modes.
- the main housing 203 is connected to the lower inner region of the secondary housing 204 through a lower connecting line 233, in which a flap 236 is located.
- a further connecting line 233 ' From the lower Paars ⁇ line 233 branches off a further connecting line 233 ', which leads to the second sub-housing 204' of the second Vormér ⁇ exchanger 250b '.
- the inlet of the connecting line 233 'in the second sub-housing 204' is dominated by a flap 236 '.
- the main housing 203 is in turn connected by an upper connecting line 234 to the upper inner area of the first secondary housing 204, which is now extended further up to the upper inner area of the second secondary housing 204 '.
- an upper connecting line 234 to the upper inner area of the first secondary housing 204, which is now extended further up to the upper inner area of the second secondary housing 204 '.
- 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 post-combustion 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. 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 shut down.
- 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 cleaned flows via the inlet pipe 228 'into the heat exchanger tubes 231' of the second preheat exchanger 250b ', through the upper plenum 222, through the heat exchanger tube 223 of the primary heat exchanger 250a, through the lower plenum 207 into the Combustion chamber 211, where the combustion of the impurities 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 in 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 1 over the open flap 239 'to Hauptauslivesstutzen 281st
- the flap positions of the two preheat exchangers 250b and 250b 1 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 lying in the inlet connection 228 of the first preheat exchanger 250b is slightly opened, as is 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 Vor ⁇ heat 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 1 remain unchanged, the flow rates change. Conditions 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 0 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.
- the exhaust air flowing through the heat exchanger tubes 231 of the first preheat exchanger 250b and carrying the burnt deposits is mixed in the upper plenum 222 with those exhaust air coming from the second preheat exchanger 250b 1 , and then with this combustion in the combustion chamber
- Combustion chamber 211 supplied.
- the third embodiment of the thermal Nach ⁇ combustion device 201 allows a highly variable mode of 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'.
