DEVICE FOR FUEL COMBUSTION IN THE ENRICHED AND DEPLETED ZONES Russian patent published in 2017 - IPC F23D14/08 

FIELD: power industry.

SUBSTANCE: fuel combustion device in the enriched and depleted zones contains the first plate 110 and the second plate 120, facing each other to provide the enriched mixture to pass between them through the rich mixture channel 173; the third plate 130, configured to provide the depleted mixture to pass through the depleted mixture channel 176, formed between the second plate 120 and the third plate 130; the first burner outlet element 140, configured to combust the enriched mixture; and the second burner outlet element 150, configured to combust the depleted mixture, wherein the mixture inlet 161 is formed between the first plate 110 and the second plate 120, to which some air amount is supplied by the fan 300 and gaseous fuel, injected from the nozzle 710, the channel supply section 171 for the mixture and channel diffuser 172 for the mixture to provide the enriched mixture passing, having passed through the mixture inlet 161 into the enriched mixture channel 173, the air inlet 162 to which the rest of the air is supplied by the fan 300, and the air channel supplying section 174, through which the air passes through the air inlet 162, at that the plurality of the air through holes 121 are formed for passing through the second plate 120, to provide the air passing from the air channel supplying section 174 into the air channel 175, formed between the second plate 120 and the third plate 130, and the plurality of distribution holes 122 are formed to pass through the second plate 120 to provide passing of some mixture amount, coming through diffusor 172 of the mixture channel into the depleted mixture channel 176.

EFFECT: invention allows to reduce NO_x and CO emissions into the atmosphere and increase the stability of fuel combustion.
