Definitions

  • the invention relates to burner devices for the partial oxidation of gaseous gasification materials.
  • the partial oxidation of gaseous gasification substances is carried out in carburetors.
  • burner devices are arranged at the head of the gasifier, by means of which the reactants in the interior of the carburetor, which usually has high pressures of 30 to 100 bar and temperatures up to 1,600 ° C, are blown.
  • POX mode non-catalytic partial oxidation
  • temperatures of up to 1600 ° C prevail in the interior of the gasifier.
  • catalytic partial oxidation ATR mode, ATR - autothermal reforming
  • the gaseous reactant streams into the gasifier are:
  • the inert gas nitrogen may also be contained in this gas stream.
  • the outlet nozzles of these gasifying agents in the gasifier can be designed as annular gap nozzles so that these endothermic gasification agents as a Schleiergas separate the two other listed reactant streams near the outlet nozzles from each other to limit the temperature load on the outlet nozzles by the otherwise taking place directly there exothermic reactions.
  • Water vapor and / or carbon dioxide have a cooling effect and thus a further thermal protection effect for the outlet nozzles due to their heat-consuming reactions with the gasification substances.
  • Gaseous, carbon-containing gasification materials with temperatures up to about 650 ° C, which contain hydrocarbons and react exothermically with the oxygen (Inlet temperatures up to approx. 650 ° C in ATR mode, usually smaller inlet temperatures in POX mode).
  • nitrogen and / or carbon dioxide reacting endothermically with the hydrocarbons or with other reaction by-products as well as the inert gas nitrogen may also be present in the gas stream.
  • temperatures in the gasifier interior determine whether the cooling of the surfaces of the burner devices includes cooling of the burners and burner mouths (nozzle cooling means), or, as in the ATR mode with the lower temperatures in the carburetor interior, other burner protection measures are sufficient, such as the introduction of Insulating material between the burners and the temperature moderation of the endothermic gasification agent reacting with the gasification material.
  • a gasification burner in a predominantly axial, vertical position at the head of the carburetor.
  • two and more gasification burners are used in the head of the carburetor.
  • the carburetor burners inject the listed reactants close together in the carburetor interior.
  • Known burners include, for example, a central exit nozzle for the oxygen-containing gasification agent surrounded by an optional annular gap exit nozzle for the gasification agent endothermic with the gasification materials, which in turn is surrounded by an outer annular gap exit nozzle for the gasification materials.
  • the gasification agents endothermically reacting with the gasification agents from the optional central annular die function as veils and temperature moderators with respect to the reactants from the central exit nozzle and the outer annular die to minimize the temperature loading of the burners.
  • combustor designs for near-site co-injection of reactants with liquid carbonaceous gasifiers and slurries and with burner cooling devices. Such solutions are disclosed, inter alia, in US Pat. Nos. 3,874,592, 4,225,175, 4,443,228, EP 0 127 273 A3, EP 0 640 679 A1, US Pat. No. 5,515,794, CA 02 287 742, EP 1 016 505 A1 and WO 2011/085744.
  • burner devices with separated outlet nozzles for the different reactants. Such solutions are known, inter alia, from the publications DE 23 03 280 A1 and US Pat. No. 3,869,244.
  • the reactant streams from the nozzles have free-jet properties and thus an intake effect, as a result of which recirculation of reacted and already cooled gases from the lower region of the reactor space into the vicinity causes the burner or outlet nozzles.
  • These cold gases are preferably sucked upwards via the peripheral regions of the carburetor interior close to the reactor wall and thus provide protection for areas near the wall in the form of lining against thermal overloading. Recirculation is intentional for these reasons, and may also be enhanced by placement options of burner nozzle exhaust nozzles or torches and other carburettor internals.
  • torch flames form below these burners, which continue downwards into vortex streets in which the hot gas fractions react with one another.
  • the burner flames are surrounded by the above-mentioned injector effect of the gas burner of gas recirculation zones, which exceed the flame cross sections of the flames many times.
  • significantly lower turbulent mixing intensities and significantly lower temperatures prevail than in the flames and in the downwardly forming vortex streets.
  • the flames are cooled by the sucked recirculation gases.
  • the reaction conversion based on the flow cross section is lower in the recirculation zones than in the flames.
  • Document EP 1 182 181 A1 discloses a premix burner block for partial oxidation processes. This is not suitable for carburetors that are operated at high pressures, since the required, very high flow velocities at the outlet from the burner block under increased pressures can not be realized. Furthermore, the burner block for carburetor temperatures of less than 1 .400 ° C is limited. These temperatures are usually exceeded in modern carburetors.
  • the document DE 37 26 875 C2 provides a water-cooled multi-nozzle burner in which the reactants in the form of the gasification gas natural gas and the exothermic gasification agent, leading through cooling water spaces are separated.
  • Such a solution is not suitable for the technical design of modern gasification burners, which require the high preheating of the gasification agent to about 400 ° C and the gasification materials to about 650 ° C. Due to the compactness of the bottom plate this would be destroyed quickly due to the high thermal stresses. Likewise, the longitudinal expansion of the non-cooled supply pipes can not be mechanically intercepted. In addition, the required weld construction is technically practically impossible. This is supported to the effect that the installation of the inwardly inclined tubes appears technically unrealisable.
  • the specified in claim 1 invention has for its object to realize a burner device for the partial oxidation of gaseous reactants so that adjusts a predominant piston flow in the carburetor interior.
  • the burner devices for the partial oxidation of gaseous gasification materials are characterized in particular by the fact that the reactants can be fed into the carburetor interior, which is hot and pressurized up to 1,600 ° C., so that a predominant piston flow instead of a predominant recirculation flow is established in the carburetor interior.

Abstract

L'invention concerne des dispositifs à brûleurs pour l'oxydation partielle de matières premières gazeuses destinées à être gazéifiées. Ces dispositifs se caractérisent en particulier en ce que les réactifs peuvent être amenés à l'intérieur du gazéifieur sous pression et chauffé jusqu'à 1 600 °C, de sorte qu'un écoulement prédominant de type piston s'établisse à l'intérieur du gazéifieur au lieu d'un écoulement prédominant de type recirculation. Le dispositif à brûleurs comprend une première isolation recouvrant l'intérieur du gazéifieur, un dispositif de refroidissement muni d'une conduite d'alimentation en fluide de refroidissement et d'une conduite d'évacuation de fluide de refroidissement, une deuxième isolation, un compartiment de distribution de matières premières à gazéifier, muni d'une conduite d'alimentation en matières premières, sur la deuxième isolation ou sur le dispositif de refroidissement pourvu d'une deuxième isolation, un compartiment à gaz inertes muni d'une conduite d'alimentation en gaz inertes au-dessus du compartiment de distribution de matières premières à gazéifier, un couvercle recouvrant le compartiment à gaz inertes et muni d'un répartiteur pour l'oxygène, ou l'agent de gazéification contenant de l'oxygène, relié à une conduite d'alimentation, des brûleurs, et une troisième isolation faisant office d'isolation entourant le dispositif de refroidissement, le compartiment de distribution de matières premières à gazéifier et le compartiment à gaz inertes.
