Definitions

  • the invention relates to an infinitely variable oil blower burner according to the preamble of claim 1
  • the aim is to create an oil blowing burner that is infinitely variable, has a stable flame with as complete a combustion as possible, and burns with a blue flame.
  • the rotating oil distributor which is preceded by a known oil flow regulator, throws the oil in finely divided form onto the inner surface of the heated evaporation device.
  • the resulting oil vapor then flows towards the combustion chamber, where it comes into contact with the combustion air from the air volume regulator and burns.
  • the burner burns oil vapor and not oil drops. This enables the desired combustion to be achieved with a blue flame. Since only the oil distributor and not the evaporation device rotates, it is possible to heat the evaporation device electrically already for the ignition process. The flame therefore burns blue immediately after ignition.
  • the rotating oil distributor acts as a wiper within the evaporation device, as a result of which incrustations and contamination are largely avoided.
  • the oil distributor and the blower are on a common shaft of a common motor.
  • a hollow shaft is used to transport the oil from the oil flow regulator to the oil distributor.
  • the metered oil from the hollow shaft reaches its surface through radial holes. From there it is flung onto the inside surface of the heated evaporator to evaporate.
  • the single figure shows an embodiment of the invention as a longitudinal section through an oil burner.
  • the oil passes from an oil quantity regulator 1 into the hollow drive shaft 2 of a drive motor 18.
  • an oil delivery pipe 3 is drawn into the shaft 2 and sealed with a seal 4 against the shaft.
  • This seal 4 is inserted into the collar 5 of the shaft.
  • shaft 2 rotates rapidly, the oil, which due to the low power of these burners, only drops flows over the oil delivery pipe 3, to the inner wall of the shaft 2, so that even if the seal 4 does not leak oil can escape.
  • the oil flow at the oil quantity regulator 1 is interrupted and the hollow drive shaft 2 is driven empty before the motor 18 is switched off, so that no oil can escape even when the seal 4 is leaking.
  • the oil then flows through the hollow drive shaft 2 to an oil distributor 7 with radial bores 8. Due to the centrifugal force during the rotation of the shaft 2 and the oil distributor 7, the oil is thrown out of the bores 8 and reaches the inner walls of an evaporation device 6, which is cup-shaped, and points with the open end in the direction of the combustion chamber 10.
  • the drive shaft 2 is passed through the bottom of this cup.
  • the evaporation device 6 is preheated when the burner is started by an electric heater 9, so that the oil on the hot inner wall evaporates spontaneously and the oil vapor flows in the direction of the combustion chamber 10.
  • the electrical heater 9 has a thermostat 11 which monitors the temperature of the evaporation device 6 and switches off the electrical heating when this additional heating is no longer necessary due to the flame reflection.
  • the oil distributor 7 also has the task of scraping off any encrustations and caking that may arise from the oil on the inner walls of the evaporation device 6, these residues being carried off in the direction of the combustion chamber by combustion air which flows through bores (12) in the bottom of the cup.
  • the burner is thereby very insensitive to fluctuations in the quality of the oil, both in terms of ash content and changes in viscosity. Due to the air flowing through the bores 12, a partial combustion occurs in the evaporation device 6, which may be desirable in order to maintain the temperature.
  • the rotating oil distributor 7 also creates an additional swirl.
  • the combustion air is conveyed by an impeller 13, which sits between the drive motor 18 and the evaporation device 6 on the drive shaft 2.
  • This impeller 13 also has the task of cooling the drive shaft 2 and the oil distributor 7.
  • a diffuser 14 is used to regulate the air volume and is controlled by a servo motor, not shown, which simultaneously actuates the oil volume regulator 1, so that oil and combustion air are changed proportionally to one another in the event of changes in output.
  • the combustion air flows outside the evaporation device 6. This is provided on the outside with insulation 15, which is designed so that the correct temperature is established on the inner wall.
  • An impeller 16 in the air flow at the mouth of the evaporation device 6 ensures intensive mixing of the combustion air with the oil vapor and thus good combustion.
  • a guide tube 17 ensures the formation of a stable flame due to a high level of retroreflection and thus safe operation of the burner.
