Definitions

  • the present invention relates to a method for Combustion of liquid fuel by means of a Oil burner in which the fuel is in a flame tube sprayed, air blown into the flame tube and exhaust gas through Suction effect of the air is returned to the flame tube and a device for implementing this method.
  • EPA 0 655 580 describes an oil burner, at which is a nozzle in a cone-like nozzle chamber is arranged.
  • the nozzle chamber has a cylindrical one Section on that on one side of an end wall and on the other side of a truncated cone Area is limited. Two protrude through the end wall Ignition electrodes.
  • the nozzle chamber is one with radial Slotted baffle plate connected to the by the side facing away from the nozzle is connected to a tube, which has slot-shaped openings. That the Breakthrough tube is coaxial in one arranged another tube. The two pipes are over one conical section joined together.
  • the whole is from surround a jacket called a mixing tube, which on End has a flange so that between the flange and an annular gap in the perforated tube is formed.
  • a mixing tube which on End has a flange so that between the flange and an annular gap in the perforated tube is formed.
  • the recirculation pipe is to facilitate the cold start an electrical resistance heater. If air is out flows into the above-mentioned annular gap, it comes to a negative pressure, which is used for the recirculation of exhaust gases the inner flame tube provides.
  • the burner described has the disadvantage of a very complicated and expensive construction. Another disadvantage is that he had an electric one for a good cold start Resistance heating is required, which is also considerable Cost factor in the manufacture and operation of the burner represents.
  • the disadvantage for the stable Burning required yellow core flame, which made it difficult power, the limits for carbon monoxide and unburned Comply with hydrocarbons and also because of Soot formation the operational safety of the burner impaired.
  • EP-A-0410 135 is a burner for liquid or known gaseous fuel, in which one of the Fuel atomizing atomizer nozzle from one Air supply line is surrounded.
  • One in a boiler room protruding burner tube is equipped with an orifice and forms a combustion chamber. There are savings in the burner tube provided with certain dimensions and proportions to Introduce exhaust gas from the boiler room into the combustion chamber. These cutouts are in the area facing the aperture provided the burner tube.
  • the atomizer nozzle comes with a fan or the like over the Air supply line is supplied with combustion air.
  • the Atomizer nozzle atomizes the fuel in a full cone shape the combustion air. Exhaust gas is created by the injection effect of combustion air and fuel through the cuts sucked into the burner tube and the flame in the Flame root added to cool the flame.
  • the burner should continue without feeding External energy have a very good starting behavior and practically quiet regardless of the shape of the furnace and burn stably.
  • the burner should continue easy to maintain and inexpensive to manufacture.
  • the essential components of the burner are intended for both the combustion of gas as well as oil. This is supposed to the burner by small changes from gas to oil or from Oil to gas can be switched.
  • this is achieved by a method where practically all of the fuel in front of the flame root goes into that recirculated exhaust gas is sprayed and evaporated in the exhaust gas, and the exhaust gas enriched with vaporized fuel with the Air is swirled.
  • the air is advantageous through a central opening in a baffle plate is blown into the flame tube and the exhaust gas at the baffle plate end of the flame tube let in that it encases the central airflow.
  • the reverse is also possible namely that the air flow encases the exhaust gas flow.
  • This brings the advantage that the fuel is central in the exhaust gas flow is atomized and the flame expand and thereby cool can burn. For constructional reasons, however, it does especially a method with a central air flow.
  • the Flame tube is in operation of the burner in a combustion chamber arranged and is therefore surrounded by exhaust gas. On the Exhaust gas is thus everywhere available on the outside of the flame tube Disposal and air can be very easily in a central Beam are fed.
  • the fuel can be injected directly into the low-oxygen and hot vacuum area sprayed become. But since a single nozzle is less prone to failure and is structurally less expensive, the fuel advantageous with a cone-shaped nozzle from the center of the air flow out of the air flow into the hot and low-oxygen exhaust jacket sprayed. It becomes the kinetic Energy from the fuel droplets used to the central Air flow to penetrate and to the periphery in the interior of the flame tube.
  • the fuel is advantageously at an angle of 30 to 45 degrees to the flame tube axis towards the inner one Wall of the flame tube sprayed.
  • the speed of the Air flow and the axial velocity component of the Fuel droplets are advantageously similar, so the kinetic energy of the fuel droplets mainly to do so can be used to cross the air flow.
  • a preferred cone jacket characteristic of a fuel nozzle has 80 °.
  • the air flow is advantageous in rotation around the Flame tube axis offset. This creates a stable Swirling the air flow with the fuel vapor / exhaust jacket.

  • the nozzle preferably sprays at an angle from 40 degrees to the flame tube axis through the fuel Airflow in the exhaust jacket. This with fuel vapor Enriched coat layer is then with the swirled central airflow.
  • the flame is hollow at the root with a circular cross section, and burns from the evaporation zone near the flame tube wall the center with the air flow.
  • Flame tube is the fire zone by the air flow cooled and oxygenated.
  • the surface of the Flame is due to its hollow shape in relation to its volume larger and therefore the flame is easier to cool than with a full one Flame bodies and the burning happens in the neighborhood to the cooling air flow and not to the hot exhaust gas.
  • the gasification zone through exhaust gas and flame tube wall heated up and the fire zone cooled by the air, there is a smaller temperature gradient between Flame root and flame tip, i.e. the flame has one balanced temperature at a low level.
  • the oxygen in the combustion chamber burns i.e. immediately after the cold start, is the Gasification zone in the hot, recirculated exhaust gas.

  • the parameters of air flow velocity and Air volume and cross section of the air flow in relation to the Flame tube cross-section have an impact on the functioning of the Brenners. Through the cross-sectional area of the air opening and the Blower output, these parameters are adjustable.
  • the air opening expediently has one Cross-sectional area of 4 to 13%, preferably 8 ⁇ 2% of the Cross-sectional area of the flame tube.
