Definitions

  • the invention relates to a burner for the combustion of liquid fuels in the gaseous state, with a stationary carburetor which has an inlet proximally and an outlet distally, a flame tube which surrounds the carburetor, the space between the carburetor and the flame tube as a recirculation path for hot Combustion gases serve to the inlet of the carburetor, and a fuel supply to the carburetor.
  • a burner is described in EP-A-232 677.
  • a burner with a burner chamber is known from DE-A 26 49 669, in the front area of which a rotating evaporator pot consisting of a base and a jacket is arranged.
  • the outlet opening of the evaporator pot is arranged at an axial distance from the end wall of the combustion chamber.
  • the jacket of the evaporator pot is surrounded by an annular deflection chamber at a radial distance, forming an injector channel through which air flows.
  • DE-A 33 46 431 for the burner described it provides a good mixture of fuel and combustion air with a sufficient excess of air, which is shown in a blue flame. However, a high excess of air is not permissible for continuous operation, since the CO2 value and thus the combustion efficiency do not meet the requirements.
  • DE-A 33 46 431 therefore set itself the task of improving the burner according to DE-A 26 49 669 in such a way that the oil vapor is mixed well with the fresh air and the combustion gas without influencing the injector effect.
  • the improved burner also has a rotating evaporator pot. This is closed on the flame side and only has an outlet for the vaporized fuel on the engine side.
  • the evaporator pot is provided with several rows of recesses distributed over the circumference and surrounded by an annular deflection chamber for the air supply. Gasified fuel and air then flow between the evaporator pot and the flame tube in two concentric streams of annular cross-section, meet a baffle ring, mix and then form a flame.
  • FR-A 2 269 029 also shows a burner which has a rotating evaporator pot which is distal, i.e. flame side, is closed.
  • the inside of the evaporator pot is lined with a wire mesh, which serves to prevent the fuel from escaping.
  • This burner requires a powerful fan with a relatively high energy consumption because both the fresh air and the air / gas mixture are deflected several times.
  • Another disadvantage is that after the burner has been switched off, a lot of fuel still evaporates from the wire network which has previously been coated with air and therefore has remained relatively cool, so that there is a strong release of unburned hydrocarbons.
  • a so-called mixing tube and a flame tube are provided coaxially with a nozzle.
  • the oil is injected through the nozzle into the mixing tube, into which the air necessary for combustion is also blown.
  • a flame then forms at the distal end of the mixing tube.
  • Part of the hot combustion gases is then recirculated to the beginning of the mixing tube by the action of an injector and mixed there with the oil / air mixture for the purpose of heat exchange. Thanks to the recirculation of some of the combustion gases, this burner enables the oil droplets in the mixing tube to be largely gasified and thus relatively good combustion with relatively little soot formation. However, this advantage is paid for by the increased formation of nitrogen oxides (NOX).
  • NOX nitrogen oxides
  • the burner requires a long flame tube.
  • the flame relaxes only after it has emerged from the flame tube, there is a relatively large flame zone with high temperatures, which favors the formation of nitrogen oxides.
  • Another disadvantage of the burner is that the mixing tube is cold at the start and therefore has no vaporizing effect. The flame is therefore sooty until the mixing tube reaches a high temperature and is able to effectively evaporate the oil that hits it.
  • JP-A-62 186 114 describes a kerosene burner which has an electrically heatable evaporator pot, into which fuel and air are introduced laterally in order to produce an air / fuel premix.
  • a mixing plate with a central opening is arranged above the evaporator pot, through which the premix can rise into a cylinder closed with a cover and can exit the cylinder through a large number of pores and through the mesh of a wire mesh, where it is ignited.
  • a number of hollow heat radiators, which have air holes, are arranged around the cylinder surrounded by the wire mesh.
  • this is achieved in a burner of the type mentioned at the outset in that a stationary mixing head with outlet openings for a combustible gas mixture is arranged at the outlet of the gasifier, that a deflection section is provided on the mixing head for deflecting the escaping gas mixture in a practically radial direction and that the flame tube extends to the end of the mixing head or only slightly beyond.
  • a combination with a stationary carburetor which has an inlet proximally and an outlet distally, a flame tube which surrounds the carburetor, the space between the carburetor and flame tube serving as a recirculation path for hot combustion gases for the carburetor inlet, a fuel supply to the carburetor and a stationary mixing head at the outlet of the carburetor, the stationary mixing head having a deflection section for deflecting the emerging gas mixture in a practically radial direction and the flame tube extending to the end of the mixing head or only a little beyond.
  • This combination contains no moving elements and is therefore very reliable. Due to the recirculation of hot gases, the gasifier is heated up, which practically prevents the formation of coking.
  • the high temperature of the carburetor also causes the fuel to evaporate reliably when the burner is switched off, so that it burns Stage there are no inadmissible emissions of unburned hydrocarbons.
  • the flame tube can be dimensioned relatively short without impairing the injection effect and thus the return of the hot combustion gases to the gasifier inlet.
  • the flame tube extends only to the end of the mixing head or only a little beyond, the mixing head at the end of the gasifier causing the flame to be in contact with the flame tube after a short distance and to come out of it and relax. This reduces the flame temperature.
  • a low flame temperature has the major advantage from the point of view of environmental protection that only little nitrogen oxides are formed.
  • Carburetor and mixing head can form a single unit.
  • the carburetor and the mixing head can be tubular.
  • the unit can then be made from a piece of pipe or from one consist of a piece of pipe shaped sheet metal. This considerably simplifies and reduces manufacturing costs.
  • an annular, radially inwardly directed section for example a constriction, is expediently provided at the outlet end of the carburetor. It is also possible to provide a radially inward extension at the inlet of the carburetor. This can be produced, for example, by flanging.
  • an electric heater is expediently arranged on the carburetor.
  • the carburetor is then heated up before the fuel supply is switched on. This avoids that unburned hydrocarbons are released to an unacceptable extent at the start of the heating process.
  • the carburetor, mixing head, deflection part, air panel and electric heater advantageously form a single structural unit. Such a unit can be easily replaced during service work.
  • the flame tube is advantageously arranged coaxially with the carburetor and with the electric heater. This results in a particularly expedient construction in which the recirculated hot combustion gases heat the carburetor evenly.
  • the combination of the electrical heating and the recirculation path has the advantage that the electrical heating can be switched off shortly after the start, because the carburetor is kept at the desired high operating temperature by the recirculated hot gases.
  • a spray rotor can be provided at the inlet, which causes a uniform distribution of the fuel in the carburetor.
  • an atomizer nozzle at the inlet. This can preferably be arranged coaxially with the carburetor.
  • the fuel can be finely distributed over the carburetor walls using an atomizing nozzle.
  • a hollow cone nozzle is particularly expediently used as the atomizing nozzle.
  • the atomizer nozzle can also be designed such that at least one spray jet with a limited scattering angle is directed against the carburetor wall.
  • the air diaphragm has a shielding section in the area of the respective spray jet. Through this section, the spray jet is then shielded from the incoming air in such a way that it safely reaches the carburetor wall. Then no oil droplets are entrained with the air flow and shipped to the mixing head.
  • the air screen is advantageously arranged at a distance from the carburetor, the gap between the air screen and the carburetor forming a recirculation inlet. Thanks to this arrangement, it is primarily the hot recirculating gases that run along the inner wall of the carburetor, while the cold air flows more inside the carburetor. Good evaporation of the fuel is thereby achieved and re-vaporization of the fuel is avoided after the burner has come to a standstill. When the burner is switched off, the carburetor is still so hot that the remaining fuel will evaporate shortly and be burned with the air that is still being pumped until the burner comes to a standstill.
  • the carburetor advantageously has a surface-enlarging center, for example a metal mesh. This increases the effective surface area of the fuel film and accelerates gasification. When using a metal mesh or a porous sintered mass, capillary forces also become effective, which facilitate the distribution of the fuel over the entire wall of the carburetor.
  • the surface enlarging Means formed by an insert which occupies the inner wall of the hollow body. Such an insert can easily be replaced when necessary for revision work. Because the liquid fuel comes into contact with the surface-enlarging metal mesh as it emerges, capillary forces are immediately effective, which endeavor to distribute it over the entire inner surface of the carburetor.
  • the insert advantageously has a practically radially inwardly projecting flange. This causes any oil droplets to be trapped and evaporated on the hot surface of the insert. For this reason, the flange of the insert is expediently arranged at the distal end of the gasification chamber.
  • a Volustat can be provided to control the fuel supply.
  • a volustat is understood to mean a device which, according to an input signal, delivers a corresponding delivery volume per unit of time, which is practically not influenced by resistances in the delivery line. The delivery volume is hardly influenced by the viscosity of the fuel.
  • An air screen with an opening for air supply to the inlet of the carburetor is advantageously provided.
  • This opening for the air supply is expediently arranged centrally and also serves as a passage for the drive shaft of a spray rotor or as a passage for an atomizer nozzle.
  • the burner shown in Fig. 1 has a motor 11 which serves to drive the fuel pump 13, the fan 15 and optionally a spray rotor 18 (Fig. 4).
  • a fuel line 19 leads from the fuel pump 13 to the carburetor 17 (FIG. 3), which is enclosed by a flame tube 21.
  • the flame tube can be easily removed by loosening the screws 23.
  • a Volustat, a solenoid valve or another suitable device 25 serves to control the fuel supply in accordance with the control commands of the heating control 26. Volustaten are supplied, for example, by the company SATRONIK, Regensdorf, Switzerland.
  • Fig. 2 now shows an easily replaceable assembly 27, which consists essentially of the carburetor 17, the mixing head 29 forming a unit with the carburetor 17 and having a deflection section 31, the air screen 35, the electric heater 39 and possibly other parts.
  • the assembly 27 is enclosed by the flame tube 21. This is relatively short. It therefore only extends to the end of the mixing head 29 or only slightly beyond.
  • the space 40 between the carburetor 17 and the flame tube 21 form a recirculation path for hot combustion gases to the inlet 41.
  • Carburetor 17 and mixing head 29 are designed as hollow rotating bodies.
  • the carburetor 17 and mixing head 29 consist of a single piece of pipe 30 which is closed at the front by a disk 31.
  • the disk 31 serves as a deflection section for the gas mixture.
  • the gas mixture generated in the mixing head can exit through a large number of outlet openings 33.
  • the outlet openings 33 are slot-shaped. However, a different shape is also possible. Since the outlet openings 33 are located in the cylindrical lateral surface 36 of the mixing head, the gases emerge on the mixing head 29 in a practically radial direction.
  • the boundary between the carburetor 17 and the mixing head 29 is formed by a constriction 37 in the exemplary embodiment shown.
  • This constriction 37 forms an annular, radially inwardly directed section 37 'at the distal outlet 42 of the carburetor 17, which prevents liquid fuel from flowing out of the carburetor 17 into the mixing head 29.
  • an inwardly directed extension 43 prevents liquid fuel from flowing out.
  • the unit 45 consisting of the carburetor 17 and the mixing head 29 is fastened, for example, to the air shield 35 by spot welding, rivets or the like with three feet 47, which can represent extensions of the tube 30. Through the Gaps between the feet 47 create recirculation inlets 49.
  • the assembly 27 is attached to an extension ring 51 of the flame tube 21, for example with screws (not shown).
  • a sealing ring 53 made of a heat-resistant material ensures a practically airtight seal. This ensures that the air necessary for combustion can only flow through the central opening 55 of the air screen 35.
  • the carburetor 17 is enclosed by the electric heater 39.
  • the electrical heater 39 is arranged concentrically to the carburetor 17 at a short distance.
  • the carburetor 17 is heated only by radiant heat. A better heat transfer is achieved if the winding of the electric heater 39 is in direct contact with the wall of the carburetor 17.
  • These can consist, for example, of an insert 57 made of a metal mesh.
  • a metal mesh creates a capillary effect through which the fuel is finely distributed over the inner wall of the carburetor.
  • the insert 57 has a practically radially inwardly directed flange 58, which serves to catch any oil droplets so that they do not get into the mixing head 29.
  • An atomizer nozzle 59 is provided at the inlet 41 of the carburetor 17. It is a hollow cone nozzle.
  • the nozzle 59 has four different spray jets 61 with a limited scattering angle. To spray these against a To protect deflection by the inflowing air, the air screen 35 has a shielding section 63 in the area of the respective spray jet 61.
  • a spray rotor 18 is provided instead of an atomizing nozzle 54, which is driven by the motor 11 (FIG. 1) via the shaft 20.
  • the fuel line 19 leads in the immediate vicinity of the spray rotor 18.
  • the ignition electrode 65 projects into the carburetor chamber.
  • the ignition in the carburetor chamber has the advantage that a pressure surge during ignition is largely avoided. So there is a soft start. The ignition also takes place quite quickly because at the start in the carburetor 17 there are higher temperatures than at the outlet openings 33 of the mixing head 29.
