摘要： A profile of piping, particularly for making a heat exchanger for a condensation boiler. The cross-section of the profile has a trapezoidal portion with two bases and two sides, and a triangular portion with a base and two sides. A first side of the trapezoidal portion coincides with the base of the triangular portion. The second side and the bases of the trapezoidal portion and the sides of the triangular portion form the inner walls of the profile. A first angle between the first base of the trapezoidal portion and the first side of the triangular portion adjacent thereto is 45°-135°, preferably 90°. A second angle between the second base of the trapezoidal portion and the second side of the triangular portion adjacent thereto is 180°-270°, preferably 225°. A coiled heat exchanger for condensation boilers providing said profile and a condensation boiler providing said heat exchanger are provided.

摘要： A heat exchanger for a gas boiler for producing hot water is provided with a casing extending along a first axis and through which combustion fumes flow; a tube along which water flows, and which is housed inside casing, and coils about the first axis to form a helix having a succession of turns; and deflecting means for directing the fumes between successive turns of a first helix portion in a first direction and between successive turns of a second helix portion in a second direction opposite to first direction; the tube forming the turns of the first helix portion has a first cross section and the tube forming the turns of the second helix portion has a second cross section different from the first cross section.

摘要： A combustion head for a burner is provided with an outer sleeve, which houses, on the inside, a first feeding device to feed a gaseous fuel into an oxidizing air flow fed along the outer sleeve by means of a pneumatic ventilation device, at least one swirl device, which is configured to cause a primary flow F1 of gaseous fuel and oxidizing air flowing out of the outer sleeve to make a helical movement, and at least one feeding channel with an annular shape, which is obtained between the outer sleeve and the swirl device in order to feed a secondary flow F2 of oxidizing air around the primary flow F1; a second feeding device being mounted on the outside of the outer sleeve and being connected to a gaseous fuel source.

摘要： A premix burner which comprises a combustion head comprising, in turn, a perforated covering element provided with a plurality of openings. The premix burner is characterised in that it is provided with a device for generating and delivering a minimum granted thermal power completely arranged inside the combustion head. Moreover, the device comprises a concave element, whose concavity faces the internal wall of the perforated covering element.
