Definitions

  • the invention relates to a burner for industrial furnaces, in which a combustion chamber is arranged in the furnace chamber, in which a mixture of fuel gas and burner air is burned and from which a flame is directed into the furnace chamber.
  • a burner of the type mentioned above is known from EP-PS 0 164 576.
  • the combustion chamber is designed as a short piece of pipe which is tapered at the end on the combustion chamber side and has an opening for the flame to exit, while the end of the combustion chamber facing away from the combustion chamber side is formed by a radial plate which is on the inner end face of the pipe is put on.
  • Openings are made in the radial plate on a circumference of the same, which allow burner air to enter the combustion chamber.
  • a tubular gas lance is led through a central opening in the plate into the interior of the combustion chamber.
  • the gas lance extends into the outside of the industrial furnace and is charged with fuel gas there.
  • the burner air already mentioned is fed to the rear of the radial plate via an interior of a recuperator arrangement.
  • the burner air supplied in this way is divided into two partial flows in the area of the radial plate mentioned, one partial flow of which enters the combustion chamber through the radial plate, while the other partial flow flows axially past the combustion chamber and at the front end of the combustion chamber as Secondary air is added to the flame.
  • a nozzle holder is provided which holds the combustion chamber in a ring around the front opening, by means of elastic bracing.
  • the gas lance is provided with an electrode which extends coaxially through it and which extends into the combustion chamber and is used there to ignite an air / gas mixture when the burner is started up.
  • the known burner therefore has the following disadvantages: Because the combustion chamber consists of only a short piece of pipe, which is closed on the inside via the radial plate, the volume of the combustion chamber cannot be changed. Different burners are therefore required for different burner capacities and possibly also for different operating conditions, the construction of which must be adapted to the desired combustion chamber volume.
  • the arrangement of the ignition electrode in the combustion chamber has the disadvantage that an unfavorable gas / air mixture is always present in the combustion chamber in connection with the air routing of the burner air when the burner is started up. If a part of the burner air is led past the combustion chamber as secondary air and, for example, only 70% of the supplied burner air gets into the combustion chamber, this can lead to ignition problems when the burner is cold started. Although attempts have been made to solve this problem, which is known per se, by supplying less gas to start the burner so that the gas / air mixture in the combustion chamber is optimized for ignition, this trick requires additional effort in controlling the burner , especially when starting up, and complicates automated operation.
  • the invention is therefore based on the object of developing a burner of the type mentioned in such a way that the disadvantages mentioned above are avoided.
  • the burner for a large number of applications, in particular performance do not need to be changed constructively, that the combustion chamber is easily accessible and that cold start difficulties are avoided.
  • This object is achieved in that an ignition chamber is provided which is separate from the combustion chamber and in which a predetermined mixture of fuel gas and burner air can be set.
  • the object underlying the invention is completely achieved in this way.
  • the invention makes it possible to provide a separate gas / air mixture there through the separate ignition chamber, so that under all operating conditions, even with a very cold burner, commissioning is possible without any problems.
  • the combustion chamber is formed by a burner tube which is tapered at an outlet end and in which a radial plate is arranged at a distance from the tapered end, it is particularly preferred if the ignition chamber is formed as part of the plate is.
  • This measure has the advantage that a structurally simple metering of the gas / air mixture in the ignition chamber is possible, which does not change even in the continuous operation of the burner, because the determining elements (bores, annular gaps and the like) cannot be changed as part of the plate.
  • the plate is arranged at the inner end of a tubular gas lance, and burner air is guided to the inner end of the gas lance, which passes through openings in the plate
  • the plate has a cavity, wherein the gas lance is connected to the cavity and the cavity has a first bore leading to the combustion chamber and a second bore leading to the ignition chamber and finally one of the openings through which burner air flows leads to the ignition chamber.
  • This measure also has the advantage already mentioned that the setting of the gas / air mixture in the ignition chamber is fixed even in long-term operation and only a simple dimensioning of the gas passages is required in order to clearly define this mixture.
  • the ignition chamber has a peripheral edge which surrounds an ignition electrode and is arranged downstream of the second bore.
  • This measure has the advantage that a defined spark gap is created because a center electrode interacts with the sharp, circumferential edge and sparks are distributed in a radial plane and penetrate the entire flow cross-section of the gas / air mixture through the ignition chamber.
  • the ignition chamber is designed to widen downstream.
  • This measure has the advantage that the flow velocity of the gas / air mixture is weakened in the region of Ignition chamber is created by expanding the cross section in the ignition area.
  • 10 designates a burner as it is used for industrial furnaces, for example for the diffusion heat treatment of metallic workpieces.
  • the burner 10 is inserted into an outer surface 11 of an industrial furnace, not shown.
  • the burner 10 passes through a furnace wall 12 by being placed with a fastening flange 13 on the outer surface 11 and being screwed there, for example.
  • the burner 10 projects at its lower end in FIG. 1 over an inner surface 14 of the furnace wall 12 and thus projects into an furnace chamber 15.
  • the feeders and control units of the burner 10, however, are arranged in an outer space 16 outside the furnace wall 12.
  • the burner 10 is provided with a total of four media inlets and outlets.
  • the burner 10 is supplied with fuel gas 20, burner air 21 and purge air 22, while exhaust gas 23 is removed from the burner 10.
  • the burner 10 preferably has an outer recuperator wall 30 and an inner recuperator tube 31.
  • the inner recuperator tube 31 in turn encloses a burner tube 32, which is preferably made of a ceramic.
  • a tubular gas lance 33 is located in the center, that is, in the longitudinal axis of the burner 10.
  • a first, hollow-cylindrical intermediate space 34 is thus formed between the outer recuperator wall 30 and the inner recuperator tube 31, through which exhaust gas is discharged.
  • a second hollow cylindrical intermediate space 35 between inner recuperator tube 31 and burner tube 32 serves for supplying burner air, while a third, also essentially hollow cylindrical intermediate space 36 between burner tube 32 and gas lance 33 is used once also for guiding burner air, but also for receiving an electrode, as will be explained in more detail below.
  • the gas lance 33 has an interior 37 through which burner gas or a mixture of burner gas and purge air can be supplied.
  • the outer recuperator wall 30 extends up to an inner side 40 of the flange 13.
  • the inner recuperator tube 31 is provided with a plurality of radial heat transfer plates 41, which are in the first intermediate space 34 on the one hand and in the second intermediate space on the other hand 35 protrude and are connected to the inner recuperator tube 31 in a heat-conducting manner.
  • the inner recuperator tube 31 runs axially further upward in FIG. 1 than the outer recuperator wall 30.
  • the inner recuperator tube 31 is held gas-tight at its upper end in FIG. 1 in a first intermediate flange 42 of the flange 13.
  • an annular space 43 is formed between the first intermediate flange 42 and the inside 40 of the flange 13, which is connected to an exhaust pipe 44.
  • the annular space 43 serves to receive and collect the exhaust gases discharged in the first intermediate space 34 and to transfer them to the exhaust pipe 44.
  • the burner tube 32 projects axially further upward in FIG. 1 than the inner recuperator tube 31.
  • the burner tube 32 is provided at the top in FIG. 1 with an outwardly bent end 48 which thus forms an annular shoulder.
  • the folded end 48 lies over an elastic seal 49, for example one O-ring, on a second intermediate flange 51 of the flange 13.
  • the folded end 48 is pressed by means of a spring ring 50 in which a cover 52 is screwed onto the flange 13 from above.
  • the spring ring 50 is only indicated very schematically, it can be formed, for example, by a metal ring which is supported by several individual springs against the cover 52 and thus presses the folded end 48 against the elastic seal 49 and thus the second intermediate flange 51. As a result, the burner tube 32 is thus clamped only at its upper end, namely elastically.
  • annular space 54 which is provided with an inlet 55 for the burner air 21.
  • the burner air 21 can thus flow via the inlet 55 and the annular space 54 into the second intermediate space 35 between the inner recuperator tube 31 and the burner tube 32.
  • the burner tube 32 is tapered at its lower end, which projects into the furnace chamber 15, as can be seen particularly clearly from FIGS. 1 and 2.
  • a channel 60 is formed in the cover 52 and is connected to the upper end of the gas lance 33.
  • the channel 60 divides outwards into two subchannels, one of which forms an inlet 61 for the fuel gas 20 and the other an inlet 62 for the purge air 22.
  • a plate 65 which extends radially in the burner tube 32 and thus forms an upper end wall for a combustion chamber 66.
  • the combustion chamber 66 thus extends at the lower end of the burner tube 32 from the radial plate 65 to the tapered end 56.
  • An electrode 67 is arranged axially in the third space 36 between the burner tube 32 and the gas lance 33.
  • the lower end of the electrode 67 opens into an ignition chamber 68, which forms an integral part of the plate 65.
  • connection 70 leads on the one hand to an ignition device 71 and on the other hand to an ion current measuring device 72.
  • An arrow 74 indicates that the cover 52 can be removed from the flange 13, together with the gas lance 33 and the plate 65 attached to it, and the electrode 67. After the cover 52 has been removed, the spring ring 50 can be removed and the burner tube 32 are pulled out.
  • the arrow 74 is intended to indicate that gas lances 33 or electrodes 67 of different lengths can be attached to the cover 52 or that even the gas lance 33 and the electrode 67 can be continuously adjusted in length, for example by means of telescopic arrangements, gas-tight bushings and the like more.
  • An arrow 80 indicates that fuel gas 20 flows into the channel 60 via the inlet 61.
  • the arrow 81 indicates that purging air 22 can be admixed to the fuel gas 20 in the channel 60 via the inlet 62.
  • the gas / air mixture now flows down the channel 60 in the direction of the arrow 82 into the interior 37 of the gas lance 33 in FIG. 1, as with an arrow 83 indicated.
  • the gas / air mixture enters the combustion chamber 66, as indicated by an arrow 84.
  • An arrow 85 indicates that burner air 21 flows in via the inlet 55 and is guided downward in the second intermediate space 35 in FIG. 1.
  • the burner air flow at the lower end of the burner tube 32, but upstream of the plate 65, is divided by a first partial air flow (arrow 86) flowing further down in the second intermediate space 85, while another partial flow (arrow 87) passes through openings 92 (FIG. 2) in the burner tube 32 and flows down there in the third space in FIGS. 1 and 2.
  • the exhaust gases occurring in the furnace space 15 rise in the direction of the arrows 91 in the first intermediate space 34 in FIG. 1, are deflected in the annular space 43 and then exit as exhaust gas 23 through the exhaust pipe 44.
  • the burner tube 32 at the tapered end 56 ends in an orifice tube 95 which is arranged in an arched end 96 in a bulged end 97 of the inner recuperator tube 31.
  • the axial length of the orifice tube 95 is dimensioned such that the burner tube 32 can expand or contract so far in the region of its operating temperatures that the orifice tube 95 runs in the annular gap 96.
  • the plate 65 can be positioned differently within the burner tube 32 in its axial position. In this way, the volume of the combustion chamber 66 can be adjusted. Since the plate 65 is arranged with radial play within the burner tube 32 and, on the other hand, is only held by the gas lance 33 and the electrode 67, only the length of the gas lance 33 or the electrode 67 needs to be varied in order to determine the axial position of the plate 65 set, as indicated by an arrow 93 in Fig. 2.
  • the plate 65 is provided in the region of its circumference with a total of five slots 100 which run inclined to the surface of the plate 65.
  • the primary air for the combustion chamber 66 passing through the slots 100 in the direction of the arrow 88 thus receives a swirl, that is to say it is introduced into the combustion chamber 66 in the circumferential direction.
  • 65 axial bores 101 are provided in the plate.
  • the plate 65 is provided with an axially upwardly projecting neck 102 which encloses a cavity 103.
  • the lower end of the gas lance 33 is inserted in a gas-tight manner, for example welded, into the upper end of the neck 102.
  • the cavity 103 is connected to the combustion chamber 66 via five bores 104.
  • the five bores 104 are arranged uniformly in a downwardly projecting end 105 of the plate 65. It goes without saying that the bores 104 can also be provided in a different number or shape or that a specific direction of the gas flowing through them can also be predetermined via the bores 104.
  • the cavity 103 in the neck 102 is connected to the ignition chamber 68 via a lateral bore 106.
  • the ignition chamber 68 is located radially next to the cavity 103.
  • the ignition chamber 68 is delimited axially upwards by a chamber wall 109 which is integrally formed on the neck 102. Below the radially extending chamber wall 109, the ignition chamber 68 is delimited on the inside by the neck 102 and on the outside by the wall of the burner tube 32.
  • the neck 102 runs into a wall part 108 which is U-shaped in the plan view in FIG. 4 and which extends from the neck 102 to the wall of the burner tube 32.
  • the wall part 108 which thus laterally surrounds the ignition chamber 68, is provided with a peripheral edge 110 below, that is to say downstream of the lateral bore 106.
  • the circumferential edge 110 is formed with sharp edges so that a spark gap 111 can form between the circumferential edge 110 as a ground counter electrode and a center electrode 112 of the ignition electrode 67.
  • the arrangement is further in such a way that the volume of the ignition chamber 68 increases from top to bottom in the illustration of FIG. 3, because a portion of the ignition chamber 68 with a larger volume adjoins the peripheral edge 110 downward.
  • the central electrode 112 is surrounded in this area with a ceramic jacket 113.
  • the ceramic jacket 113 runs with play in a bore 114 in the chamber wall 109, so that an annular gap 115 remains.
  • This partial flow 87 now branches again into a portion (arrow 88) which flows through the slots 100 and the bores 101 in the plate 65 into the combustion chamber 66, and a second portion (arrow 87a) which flows through the annular gap 115 in the ignition chamber 68 arrives.
  • the flow of the fuel gas 20 (arrow 83) in the gas lance 33 is divided into two partial flows 83a and 83b.
  • the partial stream 83a passes through the lateral bore 106 from the cavity 103 into the ignition chamber 68, while the other partial stream 83b flows down through the bores 104 into the combustion chamber 66.
  • a gas / air mixture can be set (in conjunction with the respective pressures of fuel gas 20 and burner air 21) that is optimally ignitable. Regardless of this, the gas / air mixture in the combustion chamber 66 can be adjusted, also by dimenising the corresponding cross sections at the slots 100, the bores 101 and the bores 104.
  • the burner 10 can thus be operated with gaseous or liquid fuels.
  • its area of application is not limited to the heating of industrial furnaces, but the burner 10 can also be used in furnaces of other types.
  • the ignition electrode 67 can moreover not only be used to ignite a gas / air mixture or generally a fuel / air mixture in the ignition chamber 68, for which ignition voltages in the order of magnitude between 6 and 10 kV are required, the ignition electrode 67 can also, as already with indicated the ion current measuring device 72, can be used to monitor the ongoing operation of the burner. For this purpose, with the burner running, the ion current is measured, which results in the burner atmosphere by applying a low DC voltage between the center electrode 112 and ground, this ion current then being of the order of 6 to 16 ⁇ A.
  • the design of the burner 10 can also be such that the heat transfer plates 41 additionally form a radial stabilization of the inner recuperator tube 31 in the outer recuperator wall 30.
  • the outer recuperator wall 30 can either be a separate tube or a fixed component of the furnace wall 12.
