Definitions
- the invention relates to a device for burning oxidizable components in a carrier gas comprising a gas inlet and a gas outlet, a burner with subsequent high-speed mixing chamber, a 5 combustion chamber and a heat exchanger with around
- High-speed mixing chamber arranged around, through which the gas to be cleaned flows in countercurrent to the cleaned gas and which are bent at one end.
- the object of the present invention is to design a device of the type described above in such a way that the heat exchanger is secured with 25 structurally simple means against expansions and surface damage caused by temperature and fluctuations.
- the object is achieved in that the 0 heat exchanger tubes are bent outwards at their colder ends.
- This has the advantage that the pipe ends are arranged on a much larger circumferential surface compared to inwardly bent pipes, so that easier welding and thus 5 machine suitability is achieved.
- the welded ends can be a much larger distance from each other ,
- the sheath receiving the ends does not have to be an additional component such as a drum, compared to the prior art; rather, according to one embodiment of the invention, the inner wall of an outer annular space is used as a fastening surface, through which the oxidizable
- Carrier gas having components is guided from the inlet opening to the heat exchanger tubes. Since the risk of shrinkage and warping when welding in the pipes due to the greater distance is excluded, the Q wall material can be chosen thinner so that the
- the device according to the invention can therefore prevent a preliminary burn - always associated with the highest preheating - from causing serious damage.
- the heat exchanger is already in its high temperature section
- Another advantage of the invention is that the high-temperature part of the heat exchanger acts more as a ⁇ t - first combustion chamber stage. This property occurs particularly when the volume flow rate is low - combined with a high load of flammable substances.
- Another advantage in the arrangement of the bent pipe ends on the cold side of the device is the fact that due to the low flow velocity of the media flowing inside the pipes, abrasion in the pipe bend is almost impossible.
- Heat exchanger tubes flowing gas can be supplied via the pipe bends and the bent pipe sections. This makes them
- Pipe bends are arranged in a temperature range of approximately 250 ° C - 300 ° C, so that the risk of damage due to high and rapid temperature changes as a whole or between individual pipes is almost excluded.
- the formation of scale is also ruled out here, so that consumption is impossible.
- the carrier gas is supplied from the carrier gas inlet opening to the bent ends of the heat exchanger tubes via an outer annular space running in the region of the outer wall of the device which is essentially cylindrical in shape.
- the annular space can extend into the outlet opening.
- Heat exchanger surface acts, so that not only is a preheating of the supplied fluids, but also ensured is that existing condensates have already completely evaporated before entering the heat exchanger tubes. It should also be mentioned that the preheating in the annular space reduces the expenditure on the tube heat exchanger and reduces its costs.
- the annular space extends between the carrier gas inlet and carrier gas outlet opening. Furthermore, “the invention is characterized in that the j e carrier gas inlet opening with a subsequent first
- Annular chamber is arranged in the area of the burner, the first annular chamber concentrically surrounding the burner.
- the single figure shows a device for burning oxidizable constituents in a carrier gas such as exhaust gas 0, which can also be referred to as an afterburning device.
- the device comprises a cylindrical outer jacket 12 which is delimited by end walls 13 and 15.
- a burner 14 is arranged concentrically to the axis of the casing 12, to which a high-speed mixing tube 16 and a main combustion chamber 18, which is delimited by the outer end wall, connects. It is not necessary that - as shown in the drawing - the high-speed mixing tube 16 protrudes into the main combustion chamber 18.
- An internal annular space 20 runs concentrically to the high-speed mixing tube 16, which in turn merges into a space 22 in which heat exchange / pre-combustion tubes 24 are arranged concentrically to the longitudinal axis of the device and thus to the high-speed mixing tube 16.
- the heat exchange / preburn tubes 24 themselves are connected in an outer 0 "outer, adjacent to the outer wall 12
- Annulus 26 which in turn emanates from an annular chamber 30 arranged concentrically with burner 14, which in turn merges into inlet opening 28.
- annular chamber 32 which adjoins the chamber 22 on the side opposite the annular chamber 30 5 and opens into an outlet opening 34.
- the ends 38 of the heat exchange / pre-burning tubes 24 in the region of the outlet opening 34 are bent outwards, that is to say towards the wall 12 0, so as to pass almost perpendicularly into the wall 36 of the outer annular space 26.
- the other ends of the heat exchange / pre-combustion tubes 24 open into a tube plate 42 which shields a pre-combustion space 44 surrounding the burner 14 from the space 22. 5
- the burner 14 is surrounded by a burner stem 46 which widens conically in the direction of the high-speed tube 16 and which has recesses on the peripheral surface, such as, for. B. holes 48 has.
- the high-speed tube 16 is on the burner 14 facing
- carrier gas is fed to the outer annular space 26 via the inlet opening 28 of the adjoining ring chamber 30 " , from where the carrier gas flows into the
- Heat exchange / pre-burning tubes 24 is passed.
- the gas first flows through the area in which the tubes 24 are bent outwards.
- the ends 38 are welded into the inner wall 36 of the outer annular space 26, 10. Even with a narrow heat exchanger tube packing, the
- the distance between the ends 38 can be chosen to be relatively large, so that assembly is easy.
- Heat exchanger tube ends 38 can be chosen thin, which results in 15 ' increased flexibility. This can
- High speed mixing tube 16 to be fed. After the gas is fed through the high-speed mixing tube 16 to the main combustion chamber 18, in which a strong swirling takes place at the same time, the gas passes through the inner ring space 20 into the heat exchanger / pre-combustion tubes
- the inner wall 36 of the outer annular space 26 is designed as a heat exchanger surface, along which the hot gases coming from the inner annular space 20 can flow, results in a preheating of the Opening 28 the gas supplied to the heat exchanger / pre-combustion tubes 24. This ensures that any condensate present evaporates so that deposits in the heat exchanger / pre-combustion tubes 24 cannot occur.
- the low temperature of the gas in the region of the bent ends 38 also ensures that the flow velocity is so low that the inner walls of the pipe wear away in the region of the bends. is prevented by entrained particles.
- a "cold bypass" 53 can be provided between the chamber 30 and the pre-burning chamber 44 in order to prevent cold
- Carrier gas comprising 25 oxidizable constituents, in part directly to the burner 14 or high-speed mixing tube 16. Since this area lies in the radiation area of the burner and the pre-combustion chamber - i.e. at a temperature between 600 ° C and 650 ° C - the
- Boundary wall 36 absorbs heat.
- inlet and outlet openings 28 and 34 can be arranged separately from each other, there is also the possibility that the device in vertical
- Construction can be assembled. Structurally complex measures are not necessary for this, since external pipelines are not required for the functionality of the device.
