Definitions
- the present invention relates to a premixed burner.
- the present invention relates to a premixed burner, typically of cylindrical shape and especially suitable for combustion boilers.
- premixed burners comprise a header along which a fan conveys the air-gas mixture.
- Said burners are traditionally provided with an inner liner or distributor, provided with suitable through openings and that lead the mixture to the burner surface; the latter is also provided with multiple holes or slits having much smaller size than that of the header to prevent backfires. While this known solution is functional, it shows some considerable drawbacks.
- the inner liner or distributor causes considerable unevenness of temperature on the burner surface; this is due to the fact that the mixture that flows from the inner distributor holes directly impinges the outer body, cooling it in correspondingly localised zones and thereby creating thermal gradients with consequent cyclical endurance stress, caused by the same boiler cycle. Due to the high temperatures reached, even higher than 700°C, microfissures may occur on the burner surface that over time, cause real and extended breakage; in these cases, the burner must be replaced in full, as it cannot be repaired anymore, but there is also a concrete risk of explosion due to backfire.
- EP 1813864 discloses a burner with a double-wall diffuser.
- the diffuser comprises a plate-like body with two opposite diffusion surfaces facing the outside of the formed plate-like body, with the upstream end of the diffuser closed by a further diffuser with openings peripherally located to admit the mixture between the diffusion surfaces.
- the object of this invention is to obviate the drawbacks mentioned hereinabove.
- the object of this invention is to provide a premixed burner which should not require setting up and coupling an inner distributor of the air-gas mixture to the burner itself.
- a further object of the invention is to provide a premixed burner the surface whereof should show a substantial temperature evenness in operation, preventing or at least reducing in a substantial manner the risk of formation of microfissures and backfires.
- a further object of the invention is to provide the users with a premixed burner suitable for ensuring high level of resistance and reliability over time, also such as to be easily and inexpensively constructed.
- ⁇ EP 1 813 864 discloses a burner with a double-wall diffuser.
- the diffuser comprises a plate-like body with two opposite diffusion surfaces facing the outside of the so formed plate-like body, such as to allow a combustion to take place on two
- the premixed burner of the present invention globally indicated with 10 at figure 2 and by way of an example with cylindrical or optionally truncated-cone shape, comprises a tubular body 12, generally of steel, closed on a head by a welded or crimped plate 24.
- the side surface of the tubular body 12 is provided with a plurality of small through openings or slits and holes of any shape, indicated with 14; by way of an example, said holes and slits are only represented on limited parts of body 12, it being understood that they may be made along the entire side surface of said body according to any configuration and/or size.
- the head of the tubular body 12 opposite plate 24 is closed by at least one disk 16 provided with flange 18 with circumferential lowering 18' for coupling with the inlet indicated with 20; disk 16 is preferably made in a single body with flange 18 and is provided with a plurality of holes 22, having by way of an example a circular shape and even diameter.
- Said holes 22, which extend almost by the entire surface of disk 16, in any case may have any diameter or shape and optionally be made in groups with different diameters and/or shapes, also distributed randomly on said surface of disk 16.
- Diameter, shape and distribution of holes 22 along disk 16 are, in the practice, defined upon the system calibration and vary according to the different types of burners, since such calibration is specifically intended for optimising the efficiency thereof.
- disk 16 with holes 22 replaces the traditional inner distributor; flange 18 is coupled in a known manner to the conventional header that feeds the air-gas mixture and the latter, as a consequence, enters frontally rather than circumferentially, into body 12 constituting the burner.
- disk 16 defines the distribution head of burner 10, thus making the inner distributor unnecessary.
- Experimental tests carried out by the applicant have enabled checking that the burner according to this invention ensures the same levels of efficiency of the known solutions that envisage the use of the inner distributor, with the further advantage of preventing lack of homogeneity in the heat distribution on the tubular body 12.
- a solution of this type is also suitable for burners of the combustion type on fabric, wherein the side surface is covered by a metal or ceramic fabric layer.
- Disk 16 with flange 18 is constrained by welding or crimping to the tubular body 12 and preferably has a planar development; it is also to be provided for said disk to have non-planar configuration, for example concave or convex according to specific requirements.
- the distribution head of burner 10 it is possible to provide for the distribution head of burner 10 to be composed of two disks 16, suitably spaced from one another, respectively provided with holes, slots or through openings of different shape and/or extension, or for disk 16 to be spaced from flange 18 for creating one or more circumferentially open zones for the passage of mixture.
- disk 16 with holes 22 that closes one of the heads of the tubular body 12 integrally and effectively replaces the inner distributor used on the conventional burners, with clear advantages in terms of production and assembly cost saving.
- the absence of the inner distributor moreover, prevents the localised overheating of zones of the tubular body 12 along which the flame develops, preventing the onset of breakage phenomena and above all, excluding the risk of dangerous backfires.
