Definitions

  • the present invention relates to a new gas burner, in particular for use in a domestic cooker, which reduces the quantity of dangerous products of combustion during its functioning.
  • Gases like CO and NO x are unhealthy substances, especially when released in a closed environment like a kitchen.
  • the main scope of the present invention is to carry out a new gas burner, in particular for domestic cookers, which produces a low emission of NO x and also a low emission of CO, without jeopardising the thermal efficiency and functional reliability.
  • Another scope of the invention is to modify the burner structure in such a way to allow a manufacture simple and not expensive.
  • the diagram in Figure 1 shows different curves of NO x emission in function of different flame temperatures, by using methane as combustion gas.
  • the different curves correspond to different values of the coefficient ⁇ , which is the airing rate, i.e. the ratio between the actual air mass and the stoichiometric air mass.
  • Figure 2 shows a first embodiment of a gas burner with a crown 5 from the bottom of which a plurality of straight wings 6 are radially arranged along the circular edge of the crown.
  • a structure allows to dissipate heat from the burner body by means of air convective flows, which are generated in the channels between contiguous wings.
  • Number and dimension of the wings should be chosen depending from various features, e.g. the kind of gas to be used, the burner power and the like. So, it is possible to control the flame temperature by reducing the temperature of the burner body.
  • FIGS 3 and 4 show a second embodiment of a gas burner according to the invention.
  • the heat dissipating elements are formed by wings 6 having a curved shape, so as a larger heat dissipating surface is obtained to remove a higher quantity of heat from the burner crown. In this way, the flame temperature of the burner is proportionally lowered and the NO x emission of the combustion is correspondingly reduced.
  • Figures 2-4 are also represented the ribs 7 to support the burner crown on the burner body (not shown).
  • Figure 4 show also the toothed edge 8 on the top surface of the burner crown, said toothed edge defining in cooperation with an overhanging lid (not shown) the burner flame.
  • the wings may be carried out by utilising different materials, like cast iron or ceramic, and different techniques.
  • the wings are integral with the crown of the burner.
  • the disclosed solution allows to obtain the main advantage of reducing the NO x emission of the burner during its functioning.
  • Another advantage of a burner according to the present invention is an improved stability when arranged in the cooker, because the wings increase the supporting area for the burner crown on the burner body.
