CERAMIC BURNER HEAD WITH FLOW DUCTS FOR FUEL AND OXIDIZING AGENTS LED IN PARALLEL TO THE BURNER TIP

摘要

Burners operating with combustion air as the combustion-sustaining gas and a fuel, generally a vaporizable liquid fuel, have at least one ceramic body formed with passages for these two fluids allowing heat exchange through the walls separating these passages. According to the invention, these walls are porous so that fuel in the fuel passage can traverse the wall into an adjoining air passage by evaporization on the surface. The combustion air can be heated by recuperative heat exchange from exhaust gases of the combustion chamber. Burner heads of this type can be paired in mirror-symmetrical relationship.
