A radiant infrared burner for stoves and gas systems

Abstract

 A burner for stoves or gas systems comprising a Ven­turi tube and a distribution diffuser (2) in which the gas, before passing through hole (3) in the sha­pe of a circular sector without edges through the inside, gets into contact with tongue (12) thus creat­ing a turbulence and obtaining low charges for each cm² of the section, so that the burner can also work without secondary air.

Description

[0001] The present invention concerns a radiant infrared burner for all kind of domestic and industrial stoves and heating systems, that may be applied anywhere, comprising sealed chambers and the seal­ed domestic stoves with incorporated tiled-glass structures.

[0002] It is known that the most recent orientation of the art in the gas stoves tends to eliminate open flames which oftenly cause heavy consequences due to the accidental turn out thereof.

[0003] This problem is actually solved by means of seal­ed stoves with incorporated concrete and glass structures.

[0004] It is the aim of the present invention to realize a burner for stoves and gas systems with a high efficiency and suitable for being applied anywhe­re but, in particular, in sealed chambers and systems.

[0005] The aim set forth is reached by means of a radiant infrared burner according to the present invention, working under total exclusion of secondary air, as the inlet of the primary air through the nozzles' support and the mixing chamber proves to be suffi­cient for a high efficiency combustion.

[0006] The present invention is explained in detail herein­below according to the drawings showing a preferred embodiment.

Figure 1 shows an axonometric exploded view of the whole burner.

Figure 2 shows a perspective view of the mixing cham­ber for the primary air and the nozzles' support.

Figure 3 shows an exploded lateral scheme, with an enlargement of a detail of a diffusor's hole, in a lateral and plant view.

Figure 4 shows a top view with the Venturi tube.

Figure 5 shows a plant view of the radiant net.

Figure 6 shows a lateral scheme of a variant of the body of the Venturi tube, with the views A and B of the prosecution boxes of said Venturi tube.

[0007] Referring now to the details of the invention, the following components are shown in the drawings:

[0008] - The microstretched radiant net 1, provided with two holes 6 for the fixing of the same, and with smaller holes 7 in the shape of a stretched rhom­bus for irradiating the heat, with a front edging for the immediate and uniform distribution of the heat.

[0009] - The distribution diffuser 2 in which the gas, be­fore passing through hole 3, in the shape of a sector without edges, towards the inside, gets into contact with small tongue 12 thus creating a turbulence and obtaining low charges for each cm² of the section, so that the burner might al­so work without secondary air.

[0010] - The burner body 4, built like a hollow body so that the Venturi tube, remaining at the outside, is kept cool so as to facilitate a perfect com­bustion, i.e. in total absence of CO.

[0011] - The Venturi tube 5 which, due to the shape there­of, is suitable for working with all kinds of gases without any particular adjusting.

[0012] - The mixing chamber 8 for the primary air and the nozzles' support.

[0013] - The distribution deflector 9 with incorporated net for slowing down the gas flow and thus maintain­ing a perfect distribution on the whole surface of diffuser 2.

[0014] - Two cylindrical distancers 10 for fixing, by means of screws, the whole consisting of diffu­ser 2, net 1 and reinforcing blade 13.

[0015] In the variant of figure 6 the Venturi tube 11 is longer and has a prosecution box 14 which may in­crease the efficiency thereof.

[0016] The total height of the Venturi tube may be of a­bout 35 mm.

[0017] The most evident advantages of the present inven­tion are:
- the possibility of applying the same to stoves with a built-in plane;
- compactness of the burner;
- a very reduced total encumbrance.

Claims

1. A radiant infrared burner for stoves and gas systems characterized in that it works without secondary air due to the presence of the following components:
- a microstretched radiant net (1), provided with two holes (6) for the fixing of the same, and with smaller holes (7) in the shape of a stretched rhom­bus for irradiating the heat, with a front edging for the immediate and uniform distribution of the heat;
- a distribution diffuser (2) in which the gas, be­fore passing through hole (3), in the shape of a sector without edges, towards the inside, gets into contact with small tongue (12) thus creating a turbulence and obtaining low charges for each cm² of the section, so that the burner might al­so work without secondary air;
- a burner body (4), built like a hollow body so that the Ventury tube, remaining at the outside, is kept cool and facilitates a perfect combustion, i.e. in total absence of CO;
- a Ventury tube (5) which, due to the shape there­of, is suitable for working with all kinds of gases without any particular adjusting;
- a mixing chamber (8) for the primary air and the nozzles' support;
- a distribution deflector (9) with incorporated net for slowing down the gas flow and thus maintaining a perfect distribution on the whole surface of diffuser (2);
- two cylindrical distancers (10) for fixing, by means of screws, the whole consisting of diffu­ser (2), net (1) and reinforcing blade (13).

2. A radiant infrared burner according to claim 1, cha­racterized in that the Venturi tube (11) is longer and has a prosecution box (14).
