Definitions

  • the invention relates to a burner having a burner head and arranged in the burner head burner tubes made of metal for the supply of at least one fuel and an oxidizing agent in a reaction space, wherein at least one of the burner tubes is provided with a ceramic material consisting of a lining, the inner or the Outer surface of the burner tube completely or partially covered.
  • Such burners are used, for example, in the production of synthesis gas to introduce a coal slurry (coal slurry) and an oxidant via separate feed channels in a reaction space to implement there by partial oxidation.
  • the reaction is carried out at a pressure between 1 and about 80 bar, with flame temperatures of 1200 ... 2000 ° C are achieved.
  • the service life of the burners under these conditions of use is only a few months since they are exposed to a great deal of thermal stress and the coal slurry in the supply ducts provides for a high removal of material.
  • the burners are usually cooled by the intake air. If technically pure oxygen or oxygen-enriched air is used, the cooling is usually done by cooling water.
  • the burner usually has a cooling channel on its front side and can be supplied via a welded cooling water coil with cooling water. This cooling coil tends to crack and therefore represents another weak point of such a burner.
  • a gas-cooled burner which has a thin-walled jacket tube, which consists of ceramic or is covered with ceramic.
  • the jacket tube encloses and protects internals that form supply channels for fuel and oxidant and is gas-tightly connected to the existing metal part of the burner head, with a free thermal expansion of the parts should be possible.
  • Object of the present invention is therefore to provide a generic burner, which overcomes the disadvantages of the prior art.
  • the stated object is achieved in that the ceramic cladding is connected by positive engagement with the metallic burner tube.
  • the positive connection between the ceramic cladding and the metallic burner tube is preferably carried out so that during the burner operation between the two parts always a game remains. Tensions due to different thermal expansions, which can easily lead to damage, can thereby be safely avoided.
  • the ceramic lining is arranged in the burner head so that it is supported only on the metallic burner tube, and it does not come into contact with the remaining parts of the burner head even under unfavorable operating conditions.
  • the ceramic cladding assumes no task in the connection between the burner head and burner tube. At this compound only the metallic part of the burner tube is involved, which is why they can be performed both durable and gas or fluid-tight with little effort.
  • the purpose of the ceramic cladding is to protect metallic parts of the burner to extend the burner life. It makes sense that the ceramic cladding is therefore arranged at locations which are exposed to high thermal and / or mechanical stress during burner operation.
  • the cladding of less heavily loaded areas is associated with additional costs, without necessarily leading to an extension of the burner life. Since the reaction chamber-side ends of the burner tubes are usually loaded higher than their opposite, cold ends, a preferred embodiment of the burner according to the invention provides that the ceramic lining is arranged at the reaction chamber-side end of the burner tube and extends in the longitudinal direction only over part of the burner tube length.
  • the ceramic cladding can be flush with the burner tube or project beyond the burner tube.
  • the ceramic covering consists of one piece, and is designed as a sleeve which can be arranged inside or on the outside of the burner tube.
  • the ceramic cladding may consist of any ceramic that is resistant to the conditions encountered during burner use. Preferably, however, it consists of silicon nitride, silicon carbide or aluminum oxide.
  • the ceramic cladding reduces the thermal stress placed on the burner tube at its tip during burner operation. Furthermore, it protects the metallic material of the burner tube against mechanical attacks, as they occur, for example, when solid particles are introduced via the burner tube into the reaction space. Particularly highly loaded are reaction burner, which are used in the partial oxidation of coal, wherein the coal is introduced in the form of Kohleslurry or coal dust via one or more burner tubes as feed channels in a reaction space.
  • a preferred embodiment of the invention therefore provides that the ceramic cladding delimits a feed channel through which coal slurry or coal dust can be introduced as fuel into the reaction space.
  • burner tubes which are only slightly susceptible to the form of corrosion known as metal dusting, has proved to be of great value, and which therefore has a high resistance, especially under the conditions which exist during a partial oxidation occur.
  • a further preferred embodiment of the burner according to the invention therefore provides that one or more of the burner tubes of the burner, at least at their reaction chamber side ends of a resistant to metal dusting metal alloy, in particular from a high temperature corrosion resistant, for example, aluminum-containing iron alloy exist.
  • the invention is particularly suitable for use in burners whose burner tubes have circular cross-sections and which are arranged concentrically with one another.
  • the use of the invention is not limited to such burners.
  • a burner according to the invention can be used in a large number of applications. With particular advantage, however, it can be used as a reaction burner in a device in which carbon-containing substances are converted by partial oxidation into a synthesis gas containing carbon monoxide and hydrogen as main components.
  • a part of the burner head of a reaction burner is shown, can be supplied to the Kohleslurry as a fuel and temperature moderator and oxygen as the oxidant to a reaction space to be implemented there by partial oxidation.
  • the burner head comprises the three concentrically arranged burner tubes A, I and Z, which each have a circular cross-section.
  • Oxygen O can be introduced into the downstream reaction space (not shown) via the supply channel formed by the outer burner tube A and the inner burner tube I and via the central burner tube Z, while for the supply of Kohleslurry K through the inner I and the central Burner tube Z formed supply channel is provided.
  • the reaction chamber-side end of the inner burner tube I is exposed to a strong thermal load, since it is only relatively weakly cooled by the oxygen flow.
  • the z. B. has a high resistance to metal dusting.
  • the inner burner tube I On its inside, the inner burner tube I is provided with a ceramic lining V, by which, in particular, the end piece E is protected against the mechanical stresses by the coal slurry.
  • the ceramic lining V which consists of an abrasion-resistant material, such as silicon carbide or silicon nitrite, is formed in the form of a sleeve which is positively connected to the inner burner tube I.
