Claims
- 1. Infrared emitter with luminous radiation comprising:
a supply of gas at very low pressure and of primary air at atmospheric pressure via a venturi, said supply comprising: at least one gas injector, an injector holder, a safety valve, and a gas supply connector, the infrared emitter further comprising:
a geometrical structure comprising at least one first (1), second (2), third (4) and fourth (5) concentric enclosure, a substantially horizontal upper plate (6) below which the at least first (1), second (2), third (4), fourth (5) enclosures are fixed concentrically to said plate so that the first enclosure is inside the second enclosure, the second enclosure is inside the third enclosure, and the third enclosure is inside the fourth enclosure, a central opening (7) leading an air-gas flow perpendicularly to said plate, into an interior space created by the first enclosure (1).
- 2. Emitter according to claim 1, further comprising a fifth concentric enclosure (3) arranged between the second (2) and third (4) enclosures.
- 3. Emitter according to claim 2, wherein each of the first through fourth enclosures has on a surface of revolution over 360° lateral, oblique, vertical or hemispherical walls formed from an inoxidizable, non-porous refractory material formed to be permeable and non-porous and which turns red with heat.
- 4. Emitter according to claim 1, characterised in that it comprises an upwardly directed supply of the air-gas flow directed from a bottom to a top of the emitter, the central opening (7) being contiguous with the second (2, 13) and third (4) enclosures and leading the air-gas flow perpendicularly to the upper plate into the interior space created by the first enclosure (1).
- 5. Emitter according to claim 4, having as a shape one of:
a truncated cone, having a large base directed upwards, a cylindrical shape, and a hemispherical shape, having a base of circular cross-section directed upwards.
- 6. Emitter according to claim 5, wherein the first enclosure (1) comprises in an internal volume, according to a central vertical axis of symmetry, a solid cone (10) of pre-distribution, with a base towards the plate and an apex towards a bottom at an outlet for arrival of the air-gas flow.
