Abstract The invention relates to a recovering, impulse burner for gas fuels, with double recirculation of flue gases with reduced noxious substances emission, used in uniform heating processes, in fireplaces, wherein there are obtained different temperatures of up to maximum 1300A C, the burner for gas fuels consisting of a primary air pipe (2), provided towards the anterior part with two or more rows of air orifices (b), staggered and perpendicular to the axis of the primary air pipe (2) and whose axis coincide with the ones of the gas orifices (a), and towards the rear part, with some rectangular orifices (c) inclined with an angle alpha, with values of 30...60A in comparison with the generatrices of the primary air pipe (2), and of a ceramic embrasure (16), provided to the inside with a cylindrical burning chamber (e), whose diameter is equal to the inside diameter of the tertiary air pipe (6), and with channels (f) for the hot flue gases, in connection, on the one hand, with the ring-shaped chamber formed between the internal gas pipe (8) and the external gas pipe (10), and on the other hand, with some radial orifices (g). Invenţia se referă la un arzător pentru combustibili gazo?i, recuperativ, cu impuls, cu recircularea dublă a gazelor de ardere ?i cu emisii reduse de noxe, utilizat în procese de încălzire uniformă, în focare, în care se realizează diverse temperaturi, de până la maximum 1300°C, arzătorul pentru combustibili gazo?i se compune dintr-o conductă (2) de aer primar, prevăzută înspre partea anterioară, cu două sau mai multe rânduri de orificii (b) de aer, decalate ?i perpendiculare pe axul conductei (2) de aer primar ?i ale căror axe coincid cu cele ale orificiilor (a)de gaz ?i, spre partea posterioară, cu ni?te orificii (c) dreptunghiulare, înclinate cu un unghi alpha, cu valori de 30...60° faţă de generatoarele conductei (2) de aer primar, ?i dintr-o ambrazură (16) ceramică, prevăzută la interior cu o cameră (e) de ardere cilindrică, al cărei diametru este egal cu diametrul interior al conductei (6) de aer terţiar, ?i cu ni?te canale (f) de gaze arse, fierbinţi, în legătură, pe de o parte, cu camera inelară formată între conducta(8) interioară de gaze ?i conducta (10) exterioară de gaz, iar pe de altă parte, cu ni?te orificii (g) radiale.
