Definitions

  • the invention relates to a hot gas generator with an approximately conical combustion chamber which is provided at the wide cone end with a burner device opening axially into the combustion chamber and at the opposite end with an air supply device and which has a lateral hot gas outlet in the region of the wide end.
  • Combustion chambers of the type mentioned at the outset are for engines, i.e. So basically known in small dimensions and for operation with liquid or gaseous fuels.
  • the invention has for its object to provide a hot gas generator, the burner device can also be operated with dust-like fuels, in particular flame-retardant dust-like substances.
  • the burner device has an oil or gas-loaded burner and an annularly arranged nozzle for the supply of dusty fuels, in particular synthetic resin-containing wood dust, and a nozzle for the supply of primary air.
  • the hot gas generator according to the invention has the advantage that the majority of the combustion air is conducted in countercurrent to the fuel, so that long burnout paths and intensive mixing of the dusty fuel supplied result in the flame area. Since the proportion of synthetic resin, especially in the case of dusts containing phenolic resin, only burns properly in a direct flame, this ensures almost complete burnout.
  • the intended oil or gas-loaded burner only serves as a support or pilot burner.
  • the combustion chamber is arranged upright, the burner device is arranged facing downwards at the upper end of the combustion chamber and the lower end of the combustion chamber has an ash outlet opening which opens into a combustion chamber with a burnout surface, which is provided with an additional air supply and with a supply device for particulate fuel, in particular wood waste, and with a pilot burner in the mouth area of the material supply device is.
  • This embodiment has the advantage that, in addition to the dust-like waste products, lumpy, combustible waste products, for example in the woodworking industry, wood waste, bark or the like can also be used for hot gas generation.
  • any ash particles from the combustion chamber that enter the combustion chamber and are not burned out are completely burned on the burnout surface.
  • the arrangement also has the advantage that the solid fuel introduced into the combustion chamber in the form of a dust can have a relatively high proportion of coarse grain, since these coarse-grained components which do not completely burn out in the combustion chamber can completely burn out in the combustion chamber.
  • the pilot burner for the combustion chamber is only switched on until the lining of the combustion chamber is heated up to such an extent that the combustion of the particulate fuel supplied takes place automatically.
  • the hot exhaust gases in the combustion chamber reach the combustion chamber through the ash outlet opening, where they are further heated.
  • the burnout surface is designed as a feed grate with a largely non-diarrhea grate covering. This ensures that a relatively dense ember bed forms on the burnout surface, which hinders the diarrhea of dust-like particles.
  • the combustion chamber is double-walled and that the free space between the inner wall and outer wall in the area of the burner device is provided with at least one inlet opening for cold air and at the lower end with at least one outlet opening for the hot air and that the hot air outlet opening is connected to the lower air supply device of the combustion chamber.
  • This configuration has the advantage that, on the one hand, the walls of the combustion chamber are cooled and that the air heated in this way can be introduced at the lower end as heated combustion air.
  • the lower air supply device is formed by an annular channel which is placed around the lower end of the combustion chamber and which is provided with at least one outside air inlet opening and a plurality of air passage openings opening tangentially into the combustion chamber.
  • the tangential introduction of the combustion air achieves a defined countercurrent flow of air and fuel, which at the same time ensures that the combustion chamber wall is shielded from the flame by an air curtain.
  • the tangential introduction of the main combustion air has the further advantage that the hot exhaust gases entering the combustion chamber through the ash outlet opening are included in the generated air vortices, so that stable flow conditions result in the combustion chamber and the best possible combustion of the dusty fuel is ensured .
  • the supplied combustion air and the hot exhaust gases emerging from the combustion chamber are directed upwards in a swirl flow along the inner wall of the combustion chamber.
  • fuel particles that have not completely burned out are again torn upwards and, as a result of the toroidal secondary flow that forms in the upper part of the combustion chamber, are returned to the flame, where they can burn out completely. This enables an optimal adjustment of the swirl flow.
  • the ring channel has a decreasing cross-section in the flow direction and is closed at one end opposite the air inlet opening, a second ring channel is arranged coaxially around the ring channel, with an air outlet lying laterally next to the air inlet of the first ring channel and that the second ring channel is provided with a plurality of air passage openings which open into the space between the inner and outer walls of the combustion chamber.
  • the air outlet of the second ring duct can now be connected to the suction side and the air inlet of the first ring duct to the pressure side of a hot gas fan, so that the cooling air drawn through the space between the inner and outer walls of the combustion chamber can be introduced directly into the combustion chamber as heated combustion air .
  • the inner wall of the combustion chamber is formed by tube-web tubes, which run vertically and each open at the top and bottom of a ring line, the upper ring line with the inlet and the lower ring line with the Return of a heat flow through which a heat transfer medium flows communicating with users.
  • This configuration not only has the advantage that, in addition to the generation of hot gas, it is also possible to heat a liquid and / or vaporous heat transfer medium.
  • the heat consumer (s) can be downstream heat exchangers in which air, water or, in the case of the woodworking industry, presses can be heated.
  • the design is also advantageous when using wood pulp dust containing phenol salts.
  • the more intensive cooling of the combustion chamber walls makes it possible to maintain surface temperatures which are below the melting point of the caustic soda obtained when phenol halogen is burned. It is particularly advantageous here if the tubes forming the inner walls are made web-free in the region of the hot gas outlet opening of the combustion chamber and run at a distance from one another.
  • the tubes here form a kind of grille through which the goat gases generated in the combustion chamber must flow. Airborne dust, unburned fuel particles can accumulate here and at the same time the slight cooling of the gas flow that begins when this grille flows through when phenolic resin dust is used leads to the extinguishing of some of the 6l parts . still glowing phenolic resin dust particles.
  • a hot gas channel is provided in the upper region of the combustion chamber, which extends over a part of the inner wall of the combustion chamber and the wall of which is formed from tube-web tubes, which are connected to the other tube-web tubes are connected to the inner wall and that the channel is open at one end against the rotation of the gas flow to the combustion chamber interior and opens at the other end into a gas outlet which can be shut off.
  • This arrangement has the advantage that the combustion chamber can also be operated in the part-load range if no hot gases are required for a drying process, for example downstream, nevertheless appropriate amounts of heat must be made available via the liquid or vaporous heat transfer medium.
  • the hot gas outlet of the combustion chamber is shut off, so that the hot exhaust gases now produced with a reduced fuel supply can be drawn off through the hot gas duct guided along the inner wall in the upper region, whereby their heat content is largely released to the duct walls formed from tube-web tubes .
  • the cooled exhaust gases can then be blown into the open via a dedusting device.

  • this ring channel it is possible to additionally supply air to the hot exhaust gases for control purposes, both in order to be able to regulate temperature peaks and to be able to regulate decrease fluctuations in the amount of hot gas occurring in the downstream consumer.
  • cold air or hot air produced by cooling the combustion chamber wall can be introduced here.
  • This hot air can either be directly available in an air-cooled combustion chamber or, in a liquid-cooled combustion chamber, can be heated via a heat exchanger by the heat transfer medium for cooling the inner wall of the combustion chamber.
  • the embodiment of the hot gas generator shown in a vertical section in FIG. 1 has a vertically oriented, essentially conical combustion chamber 1.

  • an exhaust gas fan working in the suction draft is arranged behind the dedusting system. Since the hot exhaust gases generated during the combustion can no longer exit through the blocked hot gas outlet opening 17, they flow through the channel 50 'and are then: drawn off via the filter system and the exhaust gas chimney. In this way, they give off their heat to the additional tubes 51 and to the parallel tubes 49 and 50, which delimit the channel 50 '.

This provides another control option for the combustion chamber.
  • the arrangement of the channels shown in FIG. 6 in the intermediate space between the outer wall and the inner wall represents a preferred embodiment which offers the least flow resistance with large amounts of air to be heated. Deviating from this, the channels can also run differently, for example helically.
  • the tubes 50 are each provided with inwardly directed deflection surfaces 57 in the area of the hot gas outlet opening 17 of the combustion chamber 1. This not only results in better guidance of the rotating gas flow in the combustion chamber along the spaced-apart tubes 50 in the region of the hot gas outlet opening, but also the retention of solid particles in the combustion chamber itself is further improved.
  • the quantities of gas flowing out via the hot gas outlet opening 17 must flow around the free edges of the deflection surfaces with a change of direction when they pass from the rotary flow of the combustion chamber, so that solid particles contained in the gas flow are kept in the rotary flow and cannot enter the hot gas exhaust line 18 via the hot gas outlet.
  • the deflection surfaces 57 are oriented obliquely inward in approximately the same direction as the rotation of the gas flow. This increases the deflecting effect of the deflecting surfaces 57, so that the separation effect is increased in the region of the free edges of the deflecting surfaces. At the same time, this ensures that at least a part of the deflecting surfaces facing the combustion chamber solid particles of the rotary flow then resume and be carried away.
  • the basic arrangement of such deflection surfaces is shown in FIG. 4.
  • the deflection surfaces 57 with regard to their orientation are adjustably connected to the respective tube 50 in order to be able to make an optimal setting.
  • each deflection surface is formed from a plurality of partial surfaces arranged one above the other and that each partial surface is fixed to the respective tube 50 with a wedge connection.
  • This makes it possible to prevent thermal stresses even with a large height of the hot gas outlet opening with a correspondingly long length of the deflecting surfaces, since corresponding expansion joints can be provided between the individual partial surfaces.
  • the arrangement of a wedge connection allows the steering surfaces to be replaced easily, since even a scaled-up wedge can be knocked out without difficulty.
  • a component for such a partial surface with a wedge connection is shown in plan and side view in FIGS. 8a, b.
  • the embodiment shown also shows a possible design for the shape of the deflection surface.
  • the flow edge 58 projecting freely into the combustion chamber is additionally angled with respect to the rotational flow (arrow 59), so that the deflection for the gas flow when entering the hot gas outlet opening 17 is intensified.
  • the component is produced, for example, as a cast part and has two eyelets 60 which encompass the tube 50 in question, into which a wedge 61 is driven, by means of which the deflection surface 57 is fixed on the tube 50. Because the openings of the two eyelets 60 run obliquely with respect to the tube axis 62, the wedge is also secured against falling out.
