Definitions

  • the invention relates generally to a method and a device for the automatic ignition and cleaning of an oil furnace, in particular a waste oil furnace.
  • the aim is to make this manual cleaning largely unnecessary and in connection therewith to significantly improve the combustion conditions in the furnace.
  • this object is achieved by the features in the characterizing part of claim 1 and the features in the characterizing part of patent claim 18.
  • this object is achieved by the measures specified in the characterizing part of patent claim 3 and in the characterizing part of patent claim 14. Appropriate embodiments of the method and the device are specified in the subclaims.
  • the slag obtained during combustion is removed by displacing the slag located on the oil layer to the outside by a discharge device.
  • the slag can build up in the area of the burner pot wall and is finally discharged through the outermost ends of the discharge device through an outlet in the area of the cleaning shaft opening, from where it falls into a collecting container arranged underneath. This collecting container can then be emptied at larger intervals.
  • the rotor blades are expediently designed so high that they can easily pass the slag into the outlet.
  • the discharge arms or rotor blades of the discharge device are expediently curved from the inside to the outside in such a way that the slag is displaced radially outwards. It has been shown that the slag collected in the slag box has burned out very well and is practically powdery as loose slag. The constant immediate removal of the slag from the surface of the oil layer in the burner pot significantly improves the combustion conditions and also favors the exhaust gas composition.
  • a rotor with two rotor blades, which sweep essentially over the entire bottom of the burner pot, is preferably used as the discharge device. It is driven by a motor which is arranged at a sufficient distance below the base plate so that the functioning of the motor is not affected by the heat generated in the burner pot.
  • the rotor is expediently arranged centrally, the oil supply also being carried out centrally.
  • an oil feed bushing is arranged coaxially around the drive shaft, which forms an annular space with a protective tube for the drive shaft, via which the oil is guided onto the base plate.
  • the rotor with a cap which is placed with its open end down on the drive shaft. The wall of the cap protruding downward can then act as a barrier in order to prevent the opening of the annular space of the oil supply bush from becoming clogged by floating slag.
  • the ignition device is characterized in that it has an ignition chamber which is relatively small in volume compared to the burner and in which an ignition electrode and a heating device are arranged. Oil is supplied through a separate inlet.
  • the ignition device can be molded onto the burner pot. A flanged ignition device is also useful, with which conventional oil stoves can also be retrofitted.
  • Fig. 1 shows a schematic representation of the lower part of an old oil furnace, in which the components which are not essential for the explanation of the automatic ignition and cleaning device have been omitted and which, in the specific embodiment, are provided in a customary manner by means of oil supply, tank cladding, combustion chamber, blower, heat exchanger and the like . Like. Is supplemented.
  • the essentially cylindrical combustion pot 9 is delimited at the bottom by a base plate 7, which is arranged on a support frame 21 of the lower part, which is only shown schematically.
  • the arrangement of the Schlackenauslasses 1 before demPutzschacht is expedient, but not necessarily.
  • Below the opening 1 there is a collecting container 3, in which the slag thrown out through the slag outlet 1 is collected.
  • the collecting container 3 is designed as a drawer which can be pulled out of the lower part of the old oil furnace for the purpose of emptying.
  • a discharge device which is generally identified by reference number 22 and is provided with at least one discharge arm 23, is expediently arranged centrally with respect to the burner pot 9 and the base plate 7.
  • the discharge device 22 is formed by a rotor which expediently has two rotor blades 23.
  • the rotor blades 23 are arranged at a short distance above the base plate 7 and sweep over a substantial part of the base plate 7.
  • the drive of the rotor, the drive shaft 24 of which is guided downwards through the base plate 7, is provided by a motor 6 arranged at a distance below the base plate 7 driven.
  • the distance at which the motor 6 is arranged below the base plate 7 is dimensioned such that the functioning of the motor is not impaired by the temperatures occurring in the burner pot.
  • An ignition chamber 5 is located on the side wall of the burner pot 9.
  • the oil is also supplied centrally through the base plate 7 in the region of the rotor arrangement.
  • an oil feed bushing 25 is arranged in the center of the base plate 7 and protrudes slightly above the base plate 7 to form an overflow.
  • the socket 25 delimits an annular space 27 with a protective tube 26 accommodated therein, into which an oil supply line 28 opens for the central oil supply.
  • the protective tube extends from the bottom of the oil supply bushing 25 upwards over a substantial length of the drive shaft 24 of the rotor, so that the rotor drive shaft prevents access of oil from the Annular chamber 27 is protected.
  • the rotor which is seated in a rotationally fixed manner on the drive shaft, comprises an essentially cup-shaped cap 29 which is mounted with its open end pointing downward on the drive shaft 24.
  • the cylindrical side wall 30 of the cap 29 extends so far down against the base plate 7 that a slight overlap occurs between the side wall 30 and the part of the oil supply bushing 25 projecting upward above the base plate 7.
  • An overflow protection tube 31 is also expediently provided, which ends at the end from below in the interior of the rotor cap 29.
  • Two rotor blades 23 are expediently arranged on the rotor cap 29. These rotor blades can be formed in one piece with the cap 29, but are expediently screwed to the cap 29, so that the rotor blades 23 can be replaced for maintenance or replacement purposes.
  • the rotor blades have a curvature from the rotor axis of rotation to the outside, so that when the rotor blades rotate, the slag floating on the oil or resting on the base plate is displaced radially outwards to the edge of the base plate 7.
  • the very slow rotation of the rotor blades does not disturb the combustion process.
  • FIG. 2 schematically shows the slag outlet 1, which is formed by an opening in the base plate 7 located in the region of the cleaning shaft.
  • the slag outlet lies outside a wall section 20 which has a surface which is perpendicular to the combustion chamber space. This wall section serves as a lock for the oil guided onto the base plate 7.
  • An inclined surface 32 extends between the upper edge of the barrier wall and the slag outlet opening 1.
  • FIG. 2 shows that the axial height of the rotor blades 23 is such that they protrude above the barrier wall 20, so that a problem-free ejection of the collected slag is ensured.
  • the operation of the cleaning device is as follows. Via the central oil supply, i.e. Via the annular space 27, the oil is guided in the direction indicated by arrows in FIG. 3 onto the base plate 7, where the oil forms a thin layer. The oil is ignited, evaporated and then burns in the usual way for oil stoves and waste oil stoves. The residues formed during the combustion of oil, in particular waste oil, due to the most varied types of impurities, collect on the base plate 7 or float on the oil layer spread out over the base plate 7.
  • This slag is discharged through the discharge device 23, which rotates continuously.
  • the rotor blades which move continuously over the bottom surface, sweep essentially over the entire bottom surface area of the burner and displace the slag radially outward, so that the slag accumulates in the outer area of the burner.
  • the pile of slag in front of the rotor blades is constantly growing. Which during the shoot Movement of the rotor blades collecting slag radially outwards grinds on the pot wall of the burner pot 9 and is finally pushed or discharged to the outside in the region of the cleaning shaft 2.
  • the slag accumulating at the radially outer end of the rotor blades 23 passes over the comparatively low barrier wall 20 and slides down into the slag box 3, possibly with simultaneous burning out. Practical experience has shown that it is sufficient to feed this slag box 3 weekly, for example to empty. It has also been shown that the slag collected in the slag box 3 is very well burned out and is practically powdery as loose slag. The speed of rotation of the rotor is expediently about one revolution per minute.
  • An automatic ignition device can be used either in conjunction with this automatic cleaning device or separately from this cleaning device, which is identified by the reference number 5 in FIG. 1 and is arranged, for example, at a distance of 5 to 10 cm from the burner base.
  • This ignition device 5 essentially comprises an ignition chamber 13, which is expediently formed by a cylindrical bush 5. With its open end, the socket 8 opens into the burner pot 9 with the interposition of an overflow 17.
  • a heating device 14, expediently in the form of a heating cartridge, and an ignition electrode 15 are arranged in the ignition chamber 13.
  • the ignition electrode 15 and the heating device 14 are expediently held in the end wall of the socket 8.
  • This end wall of the socket 8 is formed according to the embodiment of FIG. 6 by a screw cap 19, which is required by the socket 8 at can be removed for cleaning the ignition chamber 13.
  • the socket 8 is provided with an overhead oil inlet 16.
  • the transition from the ignition chamber 13 to the base plate 7 is designed as an inclined wall 18, the overflow 17 being arranged on the ignition chamber side in front of the inclined wall 18.
  • the inclined wall 18 preferably has an inclination of approximately 45 ° with respect to the horizontal.
  • the heating device is arranged so that the overflow 17 is so high that the heating device is at least partially in the oil when the ignition chamber 13 is filled with oil.
  • the ignition electrode 15 is located above the overflow 17.
  • the oil When starting the oil furnace, the oil is supplied via the ignition chamber in the manner described above, and there is preferably no separate oil supply to the burner chamber. Only when the temperature in the oven is one has reached a certain value, the oil supply is switched over, so that the oil supply then no longer takes place via the inlet 16 but for normal operation, for example again in the manner explained in connection with FIG the ignition device flows.
  • the oil supply can be switched over, for example, by a valve designed as a three-way valve.
  • the automatic ignition device can be designed as a separate structural unit and, if necessary, also be retrofitted to existing furnaces. It is also expedient if the inclined wall 18 is integrated in a compact ignition device, so that the ignition device can be directly flanged directly to existing furnaces.
  • the entire ignition device, as shown in Fig. 1, can also be arranged obliquely with respect to the furnace axis, but of course the threshold effect caused by the barrier wall 17 must be maintained.
