摘要： A combustion head (100) characterized in that it comprises the following elements:
- a fire tube (10) with a substantially cylindrical shape and having a central symmetry axis (X) and holes (11) for the recirculation of the combustion products;
- a flame disc (20), which is arranged perpendicularly to the central symmetry axis (X);
- a conical diffuser (30) with a double conical inclination;
- a nozzle (41), which is designed to atomize liquid fuel; and
- a pair of electrodes (50) for lighting the flame.摘要翻译： 1。一种燃烧头（100），其特征在于，它包括以下元件： - 具有大致圆柱形形状并且具有用于燃烧产物的再循环的中心对称轴线（X）和孔（11）的火管（10） - 火花盘（20），其垂直于中心对称轴（X）布置; - 具有双锥形倾斜的锥形扩散器（30）; - 喷嘴（41），其设计成雾化液体燃料; 和 - 用于点燃火焰的一对电极（50）。

摘要： A combustion head for a burner is provided with an outer sleeve (2), which houses, on the inside, a first feeding device (9) to feed a gaseous fuel into an oxidizing air flow fed along the outer sleeve (2) by means of a pneumatic ventilation device, at least one swirl device (16, 17), which is configured to cause a primary flow F 1 of gaseous fuel and oxidizing air flowing out of the outer sleeve (2) to make a helical movement, and at least one feeding channel (33, 39) with an annular shape, which is obtained between the outer sleeve (2) and the swirl device (16, 17) in order to feed a secondary flow F 2 of oxidizing air around the primary flow F 1 ; a second feeding device (40) being mounted on the outside of the outer sleeve (2) and being connected to a gaseous fuel source.
