Definitions

  • the present invention relates to a burner fed with a fluid fuel according to the preamble of the main claim.
  • Such fan burners are known for the fuels gas and oil. They have a flame tube, within which a fuel nozzle is mounted, which inputs the fuel centrally into the flame tube, an annular supply air channel being arranged between the flame tube and the nozzle and being fed by a blower. A certain length of the flame tube is essential to achieve an even air distribution in the annular space in front of the fuel nozzle.
  • the blower since the blower has so far been installed axially on the side facing away from the heat exchanger of the burner, the overall length of the burner / blower unit results from the addition of the overall lengths of the two parts. As the heat exchanger dimensions become smaller, this leads to an unreasonable size.
  • the present invention is therefore based on the object of creating a so-called compact unit consisting of a burner and fan, the overall length of which can be considerably reduced compared to the prior art.
  • the burner 4 protruding into the heat source 2 consists in its interior of a fuel supply 7 arranged concentrically to its axis of symmetry 6 in the form of a tube, which is connected to a gas line or oil pump, not shown.
  • an oil preheater 8 is arranged in the course of the pipeline 7.
  • the pipe 7 ends at its end facing the heat source 1 with a fuel nozzle 9.
  • the nozzle or the preheater and the pipe are supported by three regularly spaced web plates 10 on the inner jacket of a flame tube 11 which extends deep into the housing 1 of the heat source 2 .
  • the flame tube is constructed concentrically to the axis 6 and, like the tube, the preheater 8 and the nozzle 9, is a cylinder component.
  • a baffle plate 13 is arranged, which has a central recess 14.
  • An ignition electrode 15 is directed into the space between the recess 14 and the nozzle 9.
  • the flame tube is surrounded on its rear end 16 facing away from the heat source 1 by a housing 17, which is part of the construction unit 3.
  • a cylindrical annular space 18 is formed, in which, in the extension of the flame tube 11, a sleeve 19 can be displaced on the flame tube in the direction of the axis 6.
  • the flame tube 11 is provided at its rear end 16 with recesses 27 which are distributed radially over the jacket.
  • the outer jacket 22 of the housing 17 contains a housing screw 23 of the fan 5, the central axis 24 of which is parallel and at a distance from the axis 6.
  • the housing is a radial fan with a fan wheel 25, the axis of which is equally aligned with the axis 24.
  • the housing 17 is covered on the side facing away from the heat source 1 by a housing cover 22 which is recessed in a pot shape.
  • the inner wall of the pot faces both the annular space 18 and the interior 21.
  • the sleeve 19 is mounted in this lid interior, and the servomotor 20 for the sleeve is also attached to the lid. The sleeve accordingly receives both a part of the annular space 18 and a part of the central interior of the flame tube 11.
  • a radial flow fan can also be used for the radial fan.
  • the axis 24 of the motor or that of the roller then used would be parallel to the axis 6 and at a distance from it.
  • the air from the housing screw 23 of the blower 5 is first passed into the recessed cover, which has an inner radius that is considerably larger than the outer radius of the flame tube.
  • the combustion air then enters the interior of the flame tube, which is of sufficient length due to this construction. Part of the homogenization of the air vortex occurs in the interior of the recessed cover, so that the length of the flame tube is sufficient to even out the air flow.
  • the length or axial extensions of the burner or the fan lie one above the other or, depending on the assembly, next to one another, the lengths of the two components are no longer defined by the addition of the lengths of the two individual components, but only essentially due to the length of one of the components plus a small surcharge. This means that the blower / burner unit is considerably flatter than was previously possible with the prior art.
  • the unit 3 is roughly cuboid in shape and serves as an air duct for the blower inside.
  • the assembly has two large opposite sides on, of which the side 27 forms the front side, which faces the housing 1 of the heat source, while the rear side 28 is the side on which the cover 22 and the motor of the blower 5 are arranged.
  • Cover 22 and blower 5 with drive motor protrude from the rear 28, while the front end of the flame tube, which projects into the housing 2 of the heat source 1, protrudes from the front 27.
  • the present invention is therefore also based on the object of providing a pressure regulator for the air supply to a forced draft burner, so that ratio control of the fuel and air throughputs present at the burner is possible.
  • Figure two of the drawing shows an oil burner in a basic cross-sectional view, although the invention can be used for any forced draft burner regardless of the liquid or gaseous fuel.
  • the oil burner 101 consists essentially of a flame tube 103 arranged inclined in a housing 102 whose mouth 104 is a baffle plate 105 is arranged.
  • a fan 106 is further accommodated in the housing 102 and has a fan wheel 107 which is fastened to an actuating shaft 108 which is acted upon by an electric motor 109.
  • the motor is connected to a network 110, not shown, via a speed control device 111, which is connected to the motor via an active line 112.
  • An oil pump 113 is arranged on the shaft 108 of the motor 109, the housing 114 of which is fed by a fuel supply line 115 and the pressure port of which is connected via an oil supply line 116 to an oil nozzle 117 arranged in the interior of the flame tube.
  • the flame tube 103 is open at its end 118 arranged inside the housing 102 on the inlet side. With this open end, an inlet 119 in the housing communicates with the inlet 118 via the fan wheel and an air duct 120.
  • An ignition electrode 121 is arranged in the interior of the flame tube in the annular space between the oil nozzle or the line 116 and the inner jacket of the flame tube and is connected via a line 122 to an oil monitoring and ignition device.
  • a pressure measurement port 123 is connected in the form of a tube which almost extends vertically from the jacket and is led to a measured value converter 124 which is connected via a measured value line 125 to a pressure regulator 126.
  • a setpoint generator 128 is also connected via a line 127 and an atmospheric pressure generator 130 is connected via a line 129.
  • a control line 131 leads from the pressure regulator to the speed control device 111.
  • the actual value generator 130 for the atmospheric pressure can either be arranged in the combustion chamber, into which the flame of the oil burner strikes through the mouth 104. However, this actual value transmitter can also be arranged in the boiler room or in another room.
  • the setpoint generator 128 can either be adjusted manually or is assigned to a heating controller, so that, in accordance with the desired heating output, a specific setpoint results as a setpoint both for the fuel throughput and for the air throughput and thus for the air pressure value.
  • the pressure regulator works as follows:
  • the air pressure prevailing in the interior 132 within the flame tube 103 which is maintained by the blower 106, is interrogated via the measuring nozzle 123 and converted into a preferably electrical signal in the transducer 124 and made available to the pressure regulator 126 via the line 125.
  • this actual value signal is brought into a difference from the atmospheric pressure determined by the actual value transmitter 130, which is equally present at the controller via line 129.
  • This difference signal is compared to the setpoint signal from the setpoint generator 128 via line 127, and as a result of the control deviation, the voltage supply from the network 110 via line 112 for motor 109 is changed via line 131 and speed control device 111 so that the control deviation is reduced.
  • the controller here can be a proportional or an integral or a PI controller.
  • this pressure regulator is used, for example, for hot water central heating, which usually has an outside temperature-dependent flow temperature control, the setpoint for the burner's output results from the outside temperature signal.
  • a signal for a specific fuel throughput is branched off from this target value, which leads via the drive motor 109 to a specific fuel delivery rate of the oil pump 113.
  • this setpoint also serves as a setpoint for the air pressure present in the interior 132. This air pressure is kept constant by the pressure regulator at its setpoint. The heating power is therefore the reference variable for the pressure regulator 126.
  • the flame tube had a horizontal position. Since the downstream end of the flame tube is provided with a conical indentation, there is the possibility that oil dripping after the flame arrives at the outer jacket of the flame tube and the cone slope runs along. Here, the oil moves in the direction of the inflow end of the combustion tube, which can lead to contamination on the outer parts of the burner.
  • the present invention is also based on the task of preventing oil from running along the burner after the burner is closed on the outer jacket of the flame tube. For this purpose, the embodiment according to FIG.
  • a compact unit 203 consisting of a burner 204 and a blower 205, is flanged to a housing 201 of a heat source which has a heat exchanger (not shown).
  • the burner 204 projecting into the heat source consists in its interior of a fuel supply 207 arranged concentrically to its axis of symmetry 206 in the form of a tube, which is connected to an oil pump (not shown).
  • An oil preheater 208 is arranged in the course of the pipeline 207.
  • the pipe 207 ends at its end facing the heat source with a fuel nozzle 209.
  • the nozzle or the preheater and the pipe are supported by four regularly spaced web plates 210 on the inner jacket of a flame tube 211 which projects deeply into the housing 201 of the heat source.
  • the flame tube is constructed concentrically to the axis 206 and, like the tube, the preheater 208 and the nozzle 209, is a cylinder component.
  • a baffle plate 213 is arranged, which has a central recess 214.
  • An ignition electrode 215 is directed into the space between the recess 214 and the nozzle 209.
  • the flame tube is surrounded on its rear end 216 facing the heat source by a housing 217, which is part of the unit 203, and is mounted in it at an angle of 3 ° so that the lowest point 230 of the Flame tube lies where the flame tube retracts to a cone 231 at its end facing the heat source.
  • a cylindrical annular space 218 is formed, in which an extension of the flame tube 211 has a sleeve 219 slidably mounted on the flame tube in the direction of the axis 206.
  • the flame tube 211 is provided at its rear end 216 with recesses 227 which are distributed radially over the jacket.
  • the outer casing of the housing 217 contains a housing screw 223 of the blower 205, the central axis 224 of which is inclined by 3 ° and is at a distance from the axis 206.
  • the blower is a radial blower with a fan wheel 225, the axis of which is equally aligned with the axis 224.
  • the housing 217 is covered on the side facing away from the heat source by a housing cover 222 arranged on it at an angle of 3 °, which is recessed in a pot-shaped manner.
  • the inner wall of the pot faces both the annular space 218 and the interior 221.
  • the sleeve 219 is mounted in this lid interior, and the servomotor 220 for the sleeve is also attached to the lid.
  • the sleeve accordingly takes both egg NEN part of the annular space 218 and a part of the central interior of the flame tube 211.
  • the inflow end of the flame tube is at a higher level than the downstream end. As a result, it is impossible for the oil that drips after the end of combustion to migrate upward in the direction of the housing 217 and to contaminate the outside of the housing 217 or the housing.
  • the task is to lower the noise level of such a burner without changing the structural conditions of the assignment of the burner to the housing of the heat source.
  • a housing 301 of a fuel-heated heating device has an approximately cuboid shape and has an upper side 302 and a side wall 303 in which there is a recess 304 which can be covered by a burner door 305.
  • the burner in turn has a housing 306 in which the actual oil burner 307 in the form of a flame tube and a fan 309 driven by a motor 308 are accommodated.
  • the flame tube protrudes through the recess 304 into the interior 310 of the boiler and is small pliantly slanted.
  • the burner housing 306 has a vent suction opening 311, which is directed into a space 312 between the front 303 and the front 313 of the housing 306.
  • a muffler 314 is nevertheless introduced into this intermediate space 312 and arranged on the front 313 of the burner housing 306 in such a way that it covers the suction opening 311 with its outlet opening 315.
  • the suction opening is directed 180 ° to the underside 316 of the burner housing 306 and is arranged where the intermediate space 312 passes unhindered into the atmosphere; it can also be arranged on the side.
  • the muffler is made of sheet metal and has, like FIG. Five, approximately the shape of a hollow cuboid.
  • This hollow cuboid has a first narrow surface 317 and an opposite further narrow surface 320 provided with bevels 318 and 319.

  • the wide areas 323 lie against the front 313 of the burner housing 306 or face the front 303 of the heater housing 301.
  • the bevels 318 and 319 are created to leave space for ribs 324 in the area of the burner door.
  • the inlet opening is at the top 325 be provided on the narrow side 321 or 322.
  • the inlet and outlet openings of the muffler are connected to one another via a plurality of deflections which are arranged in the interior 326 of the muffler, these deflections leading to different planes.
  • a tongue 327 is introduced into the interior 326, so that a deflection of approximately 150 ° in the plane of the drawing takes place from the inlet opening 325 for the sucked-in air flow, to which a deflection occurs in the same plane around the tip 328 of the tongue connects around.
  • Figure six shows a variant of the invention in a view from the burner onto the boiler.
  • the muffler consists of a shell-like bent sheet metal part that has a broad surface 323, which has an approximately trapezoidal shape with cut corners on the base side.
  • the base side 330 has a bend 331 which points into the interior 332.
  • the roof side 333 opposite the base side 330 and the adjoining inclined sides 334 and 335 likewise have a bend 331 which is also directed into the interior 332.
  • the interior is thus closed except for the cut corners 336 of the trapezoid on the broad side and on the sides forming the circumference, it is open to the viewer.
  • the muffler 314 With the open side, the muffler 314 is attached to the side 313 of the blower 309 facing it.
  • the flanged flange is used for sealing purposes.
  • two tongues 327 are arranged, between which the air intake opening 311 of the blower 309 is arranged. There is thus an air access possibility in this air suction opening 311 from the cut corners 323 via the space between the respective tongue 327 and the inclined surface 334 around the tongue to the air suction opening.
  • the sleeve is guided by the outer jacket of the flame tube and has a more or less large tolerance or out-of-roundness in its inner diameter.
  • the size of the outer jacket of the flame tube and its roundness tolerances are also subject, which accordingly can both add up or also compensate. So it can happen that in one case the sleeve is very difficult to move on the flame tube, while in the other case there is considerable play between the sleeve and flame tube.
  • the first possibility leads to a difficult adjustment of the air supply, the second case to a considerable lack of air, whereby the fan burner burns with excess air.
