Definitions

  • the invention relates to a burner with a burner housing equipped with feeds for fuel and oxidant, which projects in the intended installation state with a burner tip into a reaction zone and to which a cooling device for cooling the burner tip is assigned.
  • Such burners are, for example, externally mixing burners, via which a liquid, solid or gaseous fuel and an oxygen-containing gas are fed into each other in a reaction zone (combustion chamber) separated from one another by flow, mixed together and ignited.
  • the burners are provided with a cooling device in which a cooling medium is passed through cooling channels, which run through the projecting into the reaction zone parts of the burner jacket.
  • cooling medium is usually used cooling water, such as in the WO 00/70102 A1 described.
  • the burner jacket of a burner is equipped with a radially surrounding the outlet nozzles of the reaction media water-bearing tract, which is in flow connection via inlet and outlet lines with a cooling water circuit.
  • GB2476253 discloses a fuel injector cooled by a heat pipe.
  • heat pipe refers to a closed system in which heat transfer medium is vaporized, which evaporates as a result of the heat supplied in a region of the heat pipe designated here as the "evaporation zone". wherein the heat pipe is designed so that the heat transfer medium at a remote from the evaporation zone portion of the heat pipe, here as Referred to as "condensation zone", condensed by heat exchange with a cooling medium and flows back within the heat pipe.
  • the heat transfer medium in the heat pipe in the region of the burner tip absorbs heat, evaporates and is supplied in the gaseous state to the thermally connected to one or more heat exchangers section (condensation zone) in which it condenses while heat to a in the heat exchanger or in the heat exchangers used cooling medium.
  • a cooling medium for receiving the heat from the heat pipe for example, a gas, in particular air, or a liquid, for example water, comes into consideration.
  • the heat is transferred from the heat pipe to a reaction medium supplied to the burner, ie fuel and / or oxidant.
  • the burner according to the invention thus comes without a guided through the burner tip cooling water circuit and the associated problems.
  • Heat pipes of the type mentioned here are known per se and are described for example in the patents US Pat. No. 3,229,759 B1 . US Pat. No. 3,532,159 B1 . DE 24 39 442 A1 . EP 0 040 255 A1 described.
  • Heat pipes can be adjusted so that they have a valve function during heat transfer. Depending on the boiling or condensation temperature of the heat transfer medium used ensures that a heat transfer takes place only above a predetermined temperature.
  • Heat pipes used in the invention may also have the shape of a closed loop or a ring in which or the Heat transfer medium from an evaporation zone into a condensation zone and is passed back through a circuit, such as in the EP 0 040 255 A1 shown. All of these variants can also be used within the scope of the invention.
  • Suitable fuels for the burner according to the invention are gaseous fuels, such as natural gas, as well as liquid fuels atomized into an aerosol or fluidized solid particles (dusts).
  • the heat transferred from the heat pipe or from the heat pipes is used for preheating fuel and / or oxidant.

  • a heat exchanger which is arranged in a feed line for fuel or for oxidizing agent.
  • thermally connect the condensation zone of the heat pipe and the heat pipes with a heat exchanger from an external Coolant is flowed through.
  • external cooling medium is understood here a medium that is not used in the context of the combustion process in the reaction chamber. is used.
  • an external cooling medium is in particular a gaseous or liquid cooling medium is used, such as air or water, wherein the external cooling medium can also be recycled in turn.
  • an external cooling medium flowed through the heat exchanger can also be used to control the temperature of the preheated reaction medium by the external cooling medium as needed, for example, depending on the temperature of the reaction medium or the temperature in the region of the burner tip, is switched on .
  • a fan can be used, which transfers the heat supplied from the heat pipe to the ambient air.
  • Yet another embodiment of the invention is characterized in that the heat exchanger (s) thermally connected to the condensation zone (s) with the condensation zones of the heat pipe (s) is / are arranged within the burner housing. This embodiment reduces the construction costs and allows the use of comparatively short heat pipes with a high heat transfer capacity.
  • such an "internal" heat exchanger can also be used in addition to one of the aforementioned “external” heat exchangers.
  • any heat transfer medium used in commercial heat pipes can be used.
  • the minimum temperature on the surface of the part of the burner (burner tip) projecting into the reaction chamber is correspondingly increased during burner operation and thus the condensation of at least some of the corrosive constituents of the reaction space atmosphere on the surface of the burner jacket is effectively avoided.
  • the energy consumption is reduced when using the burner (compared to water-cooled burners of the same power).
  • the invention is suitable both for burners that work with air as an oxidant, as well as for burners, the oxygen-enriched air (with an oxygen content of about 21 vol .-%) or pure oxygen (with an oxygen content of> 95 vol .-%), and burners, in which the oxygen content of the oxidizing agent used can be variably adjusted.
