Definitions
- the invention relates to a device for mixing and / or introduction of gases and / or liquids in a hot reaction space, which consists of at least a metal tube, the reaction chamber side end is open and which is connected to a device via which the starting materials of the device can be fed ,
- Such a device is, for example, a burner for firing a combustion chamber, which has a burner head which consists of at least one outer metal tube and an inner tube arranged concentrically therewith.
- the inner tube is used for.
- a fuel gas is passed as the supply of an oxidizing agent, while in the annular gap formed by the two tubes. If air is used as the oxidizing agent, this usually ensures adequate cooling of the burner head.
- the end of the outer metal tube is often provided with a cooling channel, which is supplied via an externally welded cooling water coil with cooling water.
- Water-cooled burners have the disadvantage that high temperature gradients between the inside and outside of the water-cooled zone can cause strong temperature stresses in the material, as a result of which cracking and leakage can occur.
- temperature zones develop in which, in conjunction with a reducing reaction space atmosphere in typical high-temperature steels, a "metal dusting" called corrosion occurs, so that removal and thus destruction of the burner material takes place.
- metal dusting called corrosion occurs, so that removal and thus destruction of the burner material takes place.
- Object of the present invention is therefore to provide a device of the type mentioned in such a way that it can be used even at high reaction chamber temperatures, if it is not equipped with a water cooling.
- This object is achieved in that the outer surface of the metal tube is surrounded by a layer of heat-insulating refractory material which extends from the reaction chamber side end of the metal tube along the tube axis, and that the metal tube at its reaction chamber end end has a wall thickness between 0.1 and 3mm is.
- the heat insulating refractory material is mounted so as to surround the metal tube over its entire length.
- the thickness of the heat-insulating layer is dimensioned so that damage to the metal tube at the expected reaction space temperatures is reliably avoided.
- the heat-insulating refractory material is a casting or ramming mass or a composite of heat-resistant fibers.
- the refractory material also has a sufficiently high mechanical and chemical stability in order to be resistant under the conditions prevailing in the operating conditions (gas vibrations, aggressive atmosphere in the reaction chamber).
- the refractory thermal insulation does not protrude beyond the metal tube. This ensures that even then defined flow conditions prevail at the reaction chamber end of the metal tube, if parts of the refractory thermal insulation dissolve during operation and defects occur.
- its reaction chamber-side end is designed with a small wall thickness, which is smaller by a factor> 10 than the actual wall thickness of the metal tube. Conveniently, the pipe wall thickness increases continuously upstream, whereby a faster removal of heat absorbed at the pipe end is achieved and overheating of the pipe end is avoided.
- a preferred embodiment of the device according to the invention provides that at least the metal tube is made of a material which provides sufficient protection against the corrosion form called "metal dusting".
- at least the metal tube is made of an oxide-dispersion-strengthened alloy, a so-called ODS material.
- the device according to the invention are starting materials whose temperatures are between 100 and 700 ° C, preferably between 200 and 600 ° C and the pressures between 1 and 100bara, preferably between 10 and 30bara, can be introduced into a reaction space, in which temperatures up to 2000 ° C prevail.
- the feedstocks are, for example, hydrocarbons and / or air or / and oxygen-enriched air and / or technically pure oxygen and / or water vapor and / or hydrogen and / or carbon dioxide and / or carbon monoxide.
- the invention is suitable for introducing liquid and gaseous hydrocarbons and preferably hydrocarbons, which consist of more than 80 vol% of methane, together with an oxidizing agent in a reaction space and burn.
- the oxidizing agent which is air or oxygen-enriched air or technically pure oxygen, is supplied in such an amount that the combustion proceeds with an air ratio of between 0.5 and 1.5.
