Definitions

  • the invention relates to a burner head for burner assemblies, with a single or multiple injector gas mixing system for the internal and / or external mixing of various combustion components, in particular fuel gases, auxiliary combustion gases and possibly liquid fuels, formed by an intermediate piece in the supply channels for the combustion components of a device connection surface up to a nozzle connection side are present, and a nozzle, which consists of a central part with channels and at least one union part, whereby for mixing at least two fuel components, the circumferentially distributed first channels assigned to a first fuel component open into first injector nozzle bores, which in turn lead to a , are connected by an annular gap between the central part and the coupling part, radial injector gap, and wherein the circumferentially distributed second channels assigned to the second combustion component are also in the radial injector gap flow out.
  • various combustion components in particular fuel gases, auxiliary combustion gases and possibly liquid fuels
  • Such a burner head is used, for example, in welding, cutting, flame or heating burners, in flame spraying devices or high-speed flame spray guns for spraying wire, rod and / or powdered spraying filler materials, as well as in high flame pressure guns, for producing synthetic diamond layers on substrate surfaces from a hydrocarbon - High speed oxygen flame with high flame pressure.
  • the burner head consists of an intermediate piece with supply channels and distributor grooves, which are connected to the supply channels, and a nozzle, which is formed from a central part with channels and a union part.
  • the fuel components are fed into the intermediate piece by means of individual, separate lines which open into the respective distributor grooves.
  • an annular gap is enclosed, which serves as a channel for a fuel component and opens into a radial injector gap, the other fuel component is also guided into the radial injector gap through nozzle channels designed as bores in the central part.
  • the distributor grooves guide the respective combustion component into the group of circumferentially distributed supply channels provided in the intermediate piece.
  • the combustion component which usually flows in at high pressure and high speed, is not distributed evenly into all the supply ducts belonging to the respective group, but rather that the combustion component in the supply ducts closest to the gas supply is led to the nozzle with higher pressure , than in the more distant supply channels.
  • This asymmetrical pressure distribution has the very disadvantageous consequence that the burner flame is not rotationally symmetrical and deviates in its flame direction from the central axis of the burner head.
  • the invention is therefore based on the object of providing a burner head which eliminates the disadvantages outlined above and which therefore produces a flame which is formed rotationally symmetrically around the burner head axis.
  • This object is achieved in that, circumferentially distributed in the intermediate piece, radial-axial pressure compensation chambers are connected on the one hand to the individual fuel component supply lines and on the other hand to the associated supply channels of the intermediate piece.
  • the radial-axial pressure compensation chambers change the flow direction of the combustion components in such a way that the more or less direct axial flow through the combustion component is prevented.
  • the cap part of the burner head according to the invention is provided with circumferentially distributed nozzle channels aligned in the installed position and completely covers the central part, towards the front side of the burner head pointing towards the flame, except for an optionally available spray additive guide channel: because with one
  • the central part of the nozzle is very hot due to the flame formation on the end face of the same, especially if, as in high-speed flame spraying, a burner chamber with an expansion nozzle is additionally attached to the end face of the burner head. Insulated cooling for the central part of the nozzle would be structurally very complex and extremely difficult because of its poor accessibility.
  • the preferred arrangement according to the invention of the central part and the union part of the nozzle shields the central part from the flame by the union part.
  • This measure in itself has the consequence that the thermal load on the central part is significantly reduced.
  • the heat generated on the end face of the burner head is dissipated inside the coupling part and thus to the outside of the nozzle, which is easily accessible to a cooling device.
  • a burner head according to the prior art which, due to the formation of the one burner component channel as an annular gap between the central part and the union part, only very few contact surfaces between these two parts, and therefore a poor heat transfer from the central part to the union part of the nozzle has eliminated in an incredibly simple manner.
  • the radial-axial pressure compensation chambers are annular. It may make sense for the individual radial-axial pressure compensation chambers of the individual burner components to be arranged on circles concentric with the central axis of the burner head. This is particularly advantageous if the individual groups of supply channels assigned to the individual fuel components are also arranged in concentric circles in the intermediate piece.
  • the radial-axial pressure compensation can take place by means of baffles integrated in the radial-axial pressure compensation chambers, which means elements which change the direction of flow and which can advantageously consist of stainless steel or brass, but which can also be formed by one or more, interchangeable filter stages.
  • baffles integrated in the radial-axial pressure compensation chambers, which means elements which change the direction of flow and which can advantageously consist of stainless steel or brass, but which can also be formed by one or more, interchangeable filter stages.
  • baffles are also designed to be annular or rotationally symmetrical.
  • the radial-axial pressure compensation chambers can also be provided with gas-permeable, porous material, which is smooth Flow through the combustion components from the distributor grooves into the nearest supply ducts is also prevented, thus ensuring the radial-axial pressure equalization.
  • the radial-axial pressure compensation chambers can be partially or completely filled with this material.
  • the gas-permeable, porous material can be a ceramic foam or a ceramic molded part; An open-pore sintered metal is advantageous for this purpose.
  • the outer fuel component guides which open into the radial injector gap, as an annular gap, but as individual, circumferentially distributed fuel component channels, the spaces between which are thermal bridges between the central part and the Form the union part.
  • This increases the heat transfer speed considerably, reduces the thermal load on the central part through better heat dissipation and prevents tensions between the central part and the union part caused by temperature differences.
  • It is structurally very simple to manufacture these fuel component channels by circumferentially distributed grooves in the central part or in the union part. The remaining, raised gaps then serve as a thermal bridge. This also has the additional advantage that an interference fit is made between the central part and the union part.
  • the throw-over part is expediently surrounded by a cooling space which holds a heat-dissipating medium, it being possible for the heat-dissipating medium to be cooling water.
  • downstream combustion chamber, the transition cone and the expansion nozzle are also surrounded by a cooling jacket, in which cooling channels are located, which are connected to the cooling space around the coupling part of the nozzle. Efficient cooling of the entire front area of the burner head is thus achieved in a simple manner with a single cooling circuit.
  • a liquid fuel component which is fed to the burner head according to the invention does not have to be an individual component, but it can advantageously also consist of a gasoline which has already been gasified and / or a liquid fuel which has already been mixed with oxygen.
  • the intermediate piece has on its device connection surface separate, gas-tightly sealed distributor grooves, into each of which a group of supply channels open.
  • These distributor grooves connect the individual fuel component supply lines to the associated supply channels of the intermediate piece or to the associated radial-axial pressure compensation chambers.
  • a spray additive guide channel is surrounded in the intermediate piece by a coaxial channel and in the central part by a coaxial ring channel, the latter opening into an annular channel which coaxially surrounds the spray additive guide channel in the coupling part: through this Channels surrounding the spray additive guide channel, the spray additive material jet emerging from the spray additive guide channel can be enveloped with a gas coaxially emerging from the end face of the burner head.
  • This gas can be a reaction gas;
  • a cooling gas which may be inert, for example, for low-melting spray additives.
  • a pressure compensation annular space is preferably arranged at least between the coaxial ring channel of the central part and the ring channel of the coupling part.
  • gas distribution bores which can be arranged between the coaxial channel of the intermediate piece and the coaxial ring channel of the central part.
  • the coaxial channels are preferably fed via an envelope gas feed line, which is connected to the coaxial channel of the intermediate piece by means of an envelope gas channel and a distributor annulus which serves for the uniform distribution of the envelope gas.
  • the coaxial channel of the intermediate piece, the coaxial ring channel of the central part and the ring channel of the coupling part are preferably flowed through with water vapor, in particular superheated water vapor.
  • water vapor in particular superheated water vapor.
  • the water vapor or the superheated water vapor which is thus fed to the flame as an additional medium, can improve the combustion, so that better energy utilization and clean, residue-free combustion result.
