Abstract (en)
A combustion head (1) for a burner provided with a nozzle (2) for atomizing a liquid fuel; the head (1) has a first body (4) adapted to receive a primary comburent flow (F1) and having a frontal wall (6) arranged to produce a swirl in the primary comburent flow (F1); and a second body (13) adapted to receive a secondary comburent flow (F2), to convey it towards a combustion chamber (CC) and to produce a swirl therein; a duct (25) and an intermediate body (20) which define a channel (C1), adapted to feed a tertiary comburent flow (F3) into the combustion chamber (CC) and having a tapered end profile which converges towards the first body (4) and the second body (13); and a frontal surface of the intermediate body (20) substantially lies on the plane defined by the frontal wall (6) of the first body (4).
