Definitions

  • the present invention relates to a premix burner for combustion of premixed gas-air mixtures.
  • Premix burners are well known to the state of the art. Some of these premix burners comprise a tubular burner body. Such a burner is described in US5022352, where it is used to heat the water of e.g. a central heating system.
  • Such premix burner comprising a tubular burner body, preferably made out of steel plate, having along its tubular burner body at least one, but usually several matrixes of burning slots and/or holes.
  • the tubular burner body is closed at one side by a so-called end cap.
  • the premix burner as known in the art may show some defects after a certain period of use.
  • premix burners nowadays are to be able to modulate the air-gas throughput over a wider range.
  • premix burners have to be able to burn very low amounts of air-gas mixtures.
  • the combustion is situated very close to the tubular burner body. The lower the throughput, the closer the flame front is situated near the tubular burner body. A part of the combustion energy will heat the tubular burner body and the end cap, so causing thermal expansion of both tubular burner body and end cap.
  • both elements being end cap and tubular burner body, due to e.g. different temperatures of both elements, or different thermal expansion coefficients of both elements.
  • the tubular body is heated to higher temperature levels, due to a closer flame front, and is so subject of more severe thermal stresses. This difference may cause thermal cracks, especially at the welding zone of both elements.
  • tubular burner bodies which are able to resist better the severe thermal expansions at the connection between tubular burner body and impermeable end cap, both parts made out of metal, usually steel plate.
  • a premix burner comprises a tubular burner body, an impermeable end cap and possibly a diffusion system, located inside the tubular burner body.
  • the tubular burner body comprises at least one matrix of burning slots and/or holes on its surface.
  • Premix air-gas mixture is blown into the tubular burner body via an appropriate inlet, usually at the lower side of the tubular burner body. Since the tubular burner body is closed at the other side by the impermeable end cap, the air-gas mixture is forced to flow, possibly via an air-gas diffuser, through the burning slots and/or holes, where combustion takes place.
  • the risk on thermal cracks may be avoided to a large extend, by welding an impermeable end cap to the longitudinal end of the tubular burner body (to be closed by this impermeable end cap) of which the surface of the impermeable end cap is at least partially curved, whereas the bending radii of each point on the impermeable end cap surface is larger than 3 times the metal thickness of the impermeable end cap material.
  • radii larger than 4 times the metal thickness of the impermeable end cap material are used.
  • the border of the impermeable end cap and the longitudinal end of the tubular burner body has to engage closely.
  • this impermeable end cap is to be welded to the longitudinal end in such a way that the curvature of the impermeable end cap surface extends outwards of the tubular burner body.
  • extending outwards from the tubular burner body is referred to as "convex”.
  • the impermeable end cap is welded to the longitudinal end over the impermeable end cap's lower border.
  • the impermeable end cap may also be connected to the tubular burner body, having a curvature extending inwards to the tubular burner body.
  • extending outwards from the tubular burner body is referred to as "concave”.
  • the impermeable end cap may be curved over its whole surface, having bending radii larger than 3 times the metal thickness of the impermeable end cap material. However, the bending radius may differ for each point of the surface of the impermeable end cap.
  • the impermeable end cap is only bent at the outer border of the impermeable end cap, where the end cap is connected to the tubular burner body.
  • the impermeable end cap is preferably substantially flat, having a bending radii being substantially infinite, "substantially infinite” is to be understood as larger than 10 times the maximum distance between to points of the border of the impermeable end cap.
  • impermeable end cap When, according to the present invention, such impermeable end cap is welded to the longitudinal end of the tubular burner body, with a concave or convex curvature, the relatively large radius or radii will enable the impermeable end cap to compensate the difference in thermal expansion between tubular burner body and impermeable end cap, during combustion of combustible gas/air mixture at the burner slots, by slightly changing the radius or radii. This slight change prevents the occurrence of too large stresses over the welding between tubular burner body and impermeable end cap. As a result, thermal cracks may be avoided.
  • the tubular burner body and the impermeable end cap are made out of metal, e.g. metal or steel plate, preferably stainless steel. Preferably the same material is used for both elements. Metal thickness' of both tubular burner body and impermeable end cap ranging from 0.2 to 1.5 mm may be used, preferably ranging from 0.2 to 1 mm, such as 0.3mm, 0.5mm, 0.6mm, 0.8mm or 1 mm.
  • Tubular burner body may be provided by different techniques. Usually, a tubular burner body is provided by rolling a tube out of a perforated metal plate. The tube is closed by welding the plate edges in axial direction, e.g. by laser of TIG-welding.
  • the impermeable end cap is pressed out of metal plate.
  • the lower border of the impermeable end cap and the longitudinal end of the tubular burner body may be welded to each other in several different ways, depending on the dimensions of the lower border of the impermeable end cap as compared to the circumference to the longitudinal end of the tubular burner body, either when the curvature is used in a concave or convex way.
  • both impermeable end cap end tubular burner body are preferably spot welded or laser welded to each other.
  • both impermeable end cap end tubular burner body are preferably spot welded or laser welded to each other.
  • the diameter is larger than 0.5cm, preferably it ranges from 2.5 to 25 cm, most usually however it ranges between 6 to 8 cm.
  • a height of the tubular burner body preferably ranges from 10 to 50 cm, most usually in the range of 10 to 20. Even so, the tubular burner body is not to be understood as having a circular cross-section when cut longitudinally. Other cross sections may be used, such as elliptic or oval cross sections.
