Embodiment Construction

[0032] The fuel nozzle system 5 of the burner 1 , denoted as a whole by 1 , has a housing 2 with a burner tube 3 which has an opening 4 at the end facing away from the housing 2 . The housing 2 has two channels 6 , 7 separated from one another, through which different substances mixed in a combustion chamber 8 , not shown in detail, in particular fuel and oxidant, flow.

[0033] The fuel nozzle system 5 is arranged substantially circular and is designed to generate a leaner mixture on at least one outer ring 12 and a richer mixture, in particular a fuel / oxidant mixture, on at least one inner ring 13 . For this purpose, the fuel nozzle system has smaller outlet nozzles 14 on at least one outer ring 12 and larger outlet nozzles 15 on at least one inner ring 13 .

[0034] Alternatively, there are fewer discharge nozzles 14 on at least one outer ring 12 and more discharge nozzles 15 on at least one inner ring 13 than on the respective other ring 12 , 13 .

[0035]The discharge di...

Abstract

The invention relates to a fuel nozzle system which is arranged in a substantially circular manner and is designed in such a way that it produces a homogeneous lean mixture on at least one outer ringand a homogeneous richer mixture, in particular a fuel / oxidant mixture, on at least one inner ring.

Description

technical field [0001] The present invention relates to a burner with reduced flame temperature. Background technique [0002] The burner has a burner head for burning fuel mixed with an oxidant, the burner head essentially having a tubular channel through which the oxidant, for example air, flows out by means of a blower and is guided here by means of a distributor system into the tubular The passage of fuel, such as gas mixing. The ignition device is used to ignite the mixture of oxidizer and fuel, thereby starting combustion. [0003] This type of burner head constitutes a burden on the environment, since the burner head will produce nitrogen oxides NO during combustion X output to the atmosphere. Accordingly, burners having burner heads in which the generation of this oxide can be reduced have been developed. [0004] A burner head is known from Italian patent document 85 622-A / 90 in which a reduction of nitrogen oxides is achieved by means of a distributor device du...
