(54)	END APPARATUS COMPRISING A PROGRESSIVE COMBUSTION HEAD FOR LOW NOX EMISSIONS AND BURNER COMPRISING THIS END APPARATUS

(57) An end apparatus (1) for a burner configured to generate a flame, comprising a supply conduit (5) for supplying a comburent and a combustion head (2) at least partially inserted into the supply conduit (5) so as to define a passage gap (9) between the combustion head (2) and the supply conduit (5) for a flow of comburent (C). In particular, the combustion head (2) comprises a plurality of outer openings (11), arranged outside the passage gap (9), configured to emit a first flow of fuel (F1) outside the flow of comburent and a plurality of inner openings (12) arranged at and/or inside the passage gap (9) adapted to introduce a second flow of fuel (F2', F2") inside the flow of a comburent.
