  "textContent": "A gas combustor has a peripheral premix burner (5), and a central diffusion burner (4) whose nozzle (6) defines an eccentric first channel (9) housing an ignition device (10), an axial second channel (11), and a third channel (12) interposed radially between the first and second channel (9, 11); the gas combustor (1) is controlled, at a first start-up step, to keep the peripheral burner (5) off and to feed a fuel gas stream (F2) along the third channel (12); at a second step, after a given load (C) is exceeded, the peripheral burner (5) is activated, and the gas stream (F2) in the central burner (4) continues to be fed along the same channel (12) as at the first step, and is regulated to reduce its flow to a value greater than zero (P2).",
