- Such burners are basically known in the art, for. B. from the German patent application DE 10 2015 220 305 A1 ,
- the known burners have the disadvantage that they offer no protection against caking on the burner head.
- they offer no possibility for supplying liquid or gaseous catalysts to reduce emissions and to influence the thermochemical reactions in the area of the burner flame or the combustion zone.
- the invention is therefore the object of developing a known burner to the effect that it is protected from caking and / or offers the possibility of feeding catalysts into the combustion zone.
- the burner according to the invention is characterized by a third supply line for a spray medium and a fluidically connected to the third supply line and arranged on the burner head spray nozzle with at least one nozzle opening for atomizing the supplied spray medium to a spray and for dispensing the spray in the burner head and / or burner flame.
- the spray medium used may be liquid or gaseous. Especially in the use of liquid spray medium speaks the present Description of spray mist. When using a gaseous spray medium typically produces a spray fog. In the context of the present description, however, for the sake of simplicity, only spray mist is discussed.
- spray therefore also includes the term “spray fog”, ie the use of gaseous spray media.
- the claimed spray nozzle has the advantage that it allows a supply of the spray medium in the atomized state in the region of the burner head and / or in the region of the burner flame or the combustion zone. This offers the advantage that caking on the burner head can be prevented. Alternatively or simultaneously, the atomized spray medium in the combustion zone acts as a catalyst for the thermochemical reactions taking place there.
- the prerequisite is that the spray medium is supplied in the correct composition and in the correct amount.
- Sprühmedium own z.
