The burner comprises a burner pipe (1, 1') that is formed from a flame pipe (3, 3') and a support pipe (2, 2') with a perforated (O, O) ram body (4, 4') and a nozzle stick (5, 5') with a combustion material nozzle (6, 6'). There is a boiler chamber between the flame pipe and the support pipe behind the re-circulation opening (11, 11'), whilst the flame pipe has a re-circulation fissure, under loading, with a cross-section inserted in the support pipe. The ram body is oriented behind the inner mouth (M) with a re-circulation channel (8, 8') in the edge region of the support pipe an from which re-circulation exhaust gases stream.
