Describing

The description contains further developments of the patent application from 7-1.1964 with the file number L 46 722 Ia / 24b. Becomes the latter applies for the additional relationship. It concerns a nozzle-free oil gasification burner for hay or waste oils regardless of viscosity and degree of contamination as a result of previous use for other purposes. It is between a pre-combustion chamber, a main combustion chamber and an intermediate chamber, with only the first two each having a separate air intake or a special air intake system own, but not the intermediate chamber. Since in the first chamber there is also evaporation through electrical glow elements can, which does not necessarily have to lead to combustion already in this spatial zone, is better generally from a Antechamber spoken.

The present invention relates first of all to the antechamber designed as a long channel in accordance with L 46 722 in such a way that this channel leads to the Pigu? ^c 2 a prior registration is carried out with a changing cross-section. As shown in the attached FIG. 2, the antechamber is designed with a wide area at its beginning, ie in the vicinity of the air intake opening (19), to initially taper approximately in the shape of a pear and then to expand again steadily from a narrowest point. The intermediate chamber (3) adjoins the zone of the last enlargement of the antechamber (5) with an opening 12. Except in the area bounded by the air tube (9), there is the same oil level in all chambers of FIG. 2 (5, 3 and 1). The wall which separates the antechamber 5 from the oil reservoir 1 is provided with an additional layer of asbestos towards the chamber 1 in order to provide thermal insulation. Approximately in the area of the smallest cross-section of the prechamber (5) a throttle point (55) is provided, which has the effect that from a certain level of the oil level, which is falling during consumption, this opening no longer increases. The design rule given for this throttle point states that it should be between 1/15 and 1/10 of the cross-sectional area of the flue pipe. The same design rule applies if the throttle point (12) in the sense of FIG. 2 of L 46 722 is provided at the end of the elongated channel.

FIG. 2 in conjunction with FIG. 1 shows the air inlet opening as / on both sides at the ends an open hole, the upper one of which is open · '

mxng du3? ch a rotatable cap (21) with different settings can be provided until closing. The cap (21) is attached to a threaded bolt (13) which penetrates a nut (17), which is attached inside the perforated tube (19). The air inlet opening to the antechamber is of decisive importance for the entire combustion process because it is the only one Represents organ for the main burning process. Absolutely closes them tight, the main burner and the gate flame go out. There is also no oil vapor escaping from the hemp burner afterwards through the exhaust pipe (11) instead. The present construction enables complete sealing as well as the smallest adjustments Differences to which the main burner reacts to a high degree. since each pressure wave from the antechamber would have to cross the perforated plate twice.

The viiand located in FIG. 2 within the intermediate chamber (3) (56) only serves to evenly distribute the in the Oil vapor that has penetrated the intermediate chamber and emerges from the intermediate chamber (3) rises through the gas guide chamber (7) into the main burner. While in Jigur 2 of L 46 722 the gas guide chamber (7) of the & wipe chamber (3) was surrounded in a ring-like manner and its inner boundary was given by the air intake pipe 9, surrounds the intermediate chamber here (3) directly the air tube (9) and only above the intermediate chamber (3) the gas guide chamber (7) begins.

Figure 1 shows the lift pipe (9) initially in a larger cross-section cylindrical shape (9a), to which a reducing cross-section Cone (9b) adjoins, on the smaller opening of which a cylindrical tube (9c) is placed, which at its other end closed by a wall (26) and on the upper part of its wall laterally all around with the perforations 25 is provided.

The combustion chamber (= main combustion chamber) is made up of a cylindrical Sheath (10) bounded on which a flue pipe with a smaller cross-section (11) is in place. Air intake groups into the combustion chamber are the already described holes 25 of the air tube (9), the yokes 28 of the base plate and the holes 29 of the combustion chamber jacket (10). In order to achieve a high degree of combustion, the following outcomes must be laying rules (+ lü $) are observed:

1. Sum of the ventilation openings (25 + 28 + 29) = 1/3 of the cross-section (clear) of the exhaust pipe (11).

2. SiBraae of the air inlet openings from the air pipe (sum of 25) = 1/10 of the light of 11.

3. Ratio of the cross-sections to the combustion chamber antel (10) 'Flue pipe (11) = 3: 2.

4.Ratio of the lightness of the upper part of the air tube (9c) to the sum of the openings in its jacket wall (sum of 25) = 3: 2.

5. Ratio of the cross-sections of the air pipe to the upper part (9c) Brake chamber jacket (10) = 1: 10.

Finally, the hole size for hole groups is 28, 25 and 29 vital. While with the hole group 28 only the point of view is decisive, the holes are so small we somehow make it possible because of the path of these air intake currents in the i'lamiaenkern the smallest is and the ü-rerize only through Sooting risk is caused, must be with the yoke groups 29 and 2 ^ the hole size in a certain proportion to that by the Air currents stand to be penetrating distance. The air flows from the perforations 29 must reach the middle of the combustion chamber (middle of lü) can advance, the perforations 25 in turn release air flow currents, which must reach up to the wall of 10. After between the number of holes 25 and the decisive for the move Abzusgrohr (11) above when sentence 2 resulted in the ratio 1:10, surprised it is not, for the hole diameter 29 in relation to half the diameter of the combustion chamber jacket (= distance to be penetrated ke) and for the hole diameter 25 (at least for the majority Number of holes 25, i.e. at least $ 75) in relation to their distance (= half the diameter of 10 minus half the diameter from 9c) to find the same ratio 1:10. The sentences are called:

7. Hole diameter of the air inlet openings of the combustion chamber (gf of 29) = 1/10 of the radius of the combustion chamber.

To provide air cooling for the lower part of the burner and at the same time To achieve preheating for the air entering at 23, an air chamber was already provided in ITig.l of L 4b 722, here with the inlet openings 27 and 24 a and b. Has been added thermal insulation with asbestos (23) and another ZwisebHöB-Taum to the upper wall of the oil container.

The area of the pre-combustion chamber should not exceed the focal point of the oil concerned, i.e. usually approx. 1O5 ° G. In order to achieve this, the thermal insulation of the oil container from the burner was made by various means (27, 23) and inside the insulation of the pre-combustion chamber from the others! Parts of the container (56 in FIG. 2) and the throttle point are provided within or at the end of the antechamber (55 in FIG. 2). Despite · of these measures is the oil temperature from remaining a certain The amount of oil in the container depends on the rule that if there is only one oil left, it is five times as large corresponds to the hourly consumption (maximum consumption), must be refilled. However, this is the case when the burner is used outdoors Worsening of the burn, which occurs when the bacha falls Revenge soot value 3 to 4 expresses, hardly of importance.

FIG. 3 shows the use of the oil burner for heating buildings. In the case of permanent installation, it is advisable to connect the oil container (61) to an oil reservoir (62), either according to FIG Provide a so-called float system, i.e. driving with a constant oil level or, according to the system of communicating chambers, an ongoing oil level check at the reservoir must be observed. The combustion chamber and the lower part of the flue pipe is thermally insulated (56,57,58) from the space in which the oil container is located to keep them under certain temperatures for the reasons described above. The construction of the oil container (61) with a removable lid (71) makes cleaning easier, which cannot be done without, because the often used, often free, waste oils are naturally used are more residue. Provide insulation (56, 72) when passing the exhaust pipe (11) through ceilings and roofs dial βγΓοτίΙ j.j-lLoh '".

FIGS. 4 and 5, in conjunction with FIG. 6, show a novel "heating column system". The thermally non-insulated parts of the flue pipe (11) or the siphon pipes (96, 97, 98, 99, 100, and 102) can be surrounded by shell bodies of semi-cylindrical or other shape that can be opened in a shrine-like manner, which either cause complete thermal insulation or else Exercise a heat-storing function, for example, if they are designed with tiles that are held by appropriate frames. In this vVeise in a room, the heat emission can be prevented (by closing fully thermally insulating shells) or in the time scale of the tiled stove ^W: irm ο ρ- tr ah lung are brought or duivn certain degrees of opening a fast-acting luftumwällzungs-

system can be achieved, which on the one hand the quick effect radiating hot metal body, on the other hand the room air systematically puts into circulation. In Figure 4, the vertical position of the heating column, the air is circulated from the lower opening of the shell 66 through the space formed by the flue pipe 11 and this shell 66 to the upper opening. That makes by the fact that the bowls never reach all the way to the floor and never all the way to the ceiling. If, for example, in room 81 of FIG If these shells are attached, then the lower part of the pipe is intended 97 covered by insulation 87 and the upper one by insulation 88. If the shells are opened, which are only the free part 97 Surrounded by FIG. 6, an entry opening remains free from below and an access opening from above. This creates an ideal Form of convection (heat flow in the room). It is similar if we carry out the arrangement of FIG. 5 in space 79 of FIG. 6! In the direction of the arrow 68, heated air rises through the openings 70 to the (insulated) ceiling and draws in cold air. While closing of the shells, the openings 70 also close because they are filled by insulating bodies (69) which are attached to the tube 11 are. The horizontal heating column, installed near the floor, e.g. in room 80 (100) or room 82 (102), is suitable for absorption cold drafts such as those found in windows. In the attic of Figure 6 is a hot water storage tank at the end of the flue pipe (11) (103) provided. In the crossing part 86 located on the ceiling of the room 78 there is a throttle valve (85), which is located at the lowest Pressures that should occur from the burner (61), moved in the upward direction, so that the shortest path to the exit of 11 is released. Similar throttle valves can be attached to a wide variety of Attach parts of the system to heat certain arms to a greater or lesser extent.

Does not value complete electrical independence of the system there are other combinations, especially with fans for air circulation or to increase the heating power (for example attached to act on the air tube 9 at the opening 9a) possible. The air inlet opening 19 (iig.l and 2) is thermostatic adjustable.
