Abstract:
1. Device comprising: a burner that provides for combustion of a fuel/oxidant mixture, having a combustion temperature above 2500° C., within a combustion chamber at a temperature below said combustion temperature; a material which endures a maximum temperature that is less than the combustion temperature of said fuel and said oxidant, said material being provided in said combustion chamber; supply lines for the fuel as well as the oxidant, in order to conduct these into the combustion chamber; at least one additional supply line connected to a low combustion value gas supply in order to conduct a low combustion value gas into the combustion chamber that allows the temperature during combustion to be lowered to a value below the maximum temperature; and a pre-mix chamber that provides for mixing of said fuel and oxidant, wherein said fuel and oxidant are added to said pre-mix chamber separately by means of tangentially arranged supply lines, and wherein said material is a porous material with inter-connected hollow spaces suitable in size for flame development.
