Definitions

  • the invention relates to a nozzle for a gas burner according to claim 1.
  • a nozzle for a burner wherein the nozzle has a channel, wherein in the channel a pin is provided with a guide surface for guiding a fuel.
  • a burner for fossil fuels wherein the burner has a nozzle which emits fuel into a channel, wherein a flow-shaping element is arranged in the channel. After the flow-shaping element, the outlet opening of the channel is provided.
  • a nozzle for a gas burner according to the preamble of the first claim wherein the nozzle has a channel with an outlet opening, wherein a flow element is arranged outside the outlet opening, wherein the flow element is fastened via a sleeve in the channel.
  • a nozzle for a gas burner wherein a channel is provided, wherein the channel has an outlet opening, wherein outside of the outlet opening a flow element is provided, wherein the flow element has a gyro plate and a spaced apart in the flow direction mushroom head as another flow element.
  • the object of the invention is to provide an improved nozzle for a gas burner.
  • An advantage of the described nozzle is that the fuel is efficiently fluidized with air by the nozzle with little pressure loss. This is achieved in that the nozzle has a channel in which the fuel is conveyed, wherein a flow element is provided, which is arranged outside the outlet opening of the nozzle.
  • the flow element is designed in such a way that an optimal turbulence of the fuel with air, which is conveyed outside the nozzle along the nozzle, takes place.
  • due to the shape of the flow element a small pressure drop is achieved.
  • the flow element is arranged outside the outlet opening, and that the cross section of the flow element increases with increasing distance to the outlet opening.
  • a guide surface is provided, which leads away the fuel from a center axis of the nozzle and thus efficiently mixed with an air flow, which flows along an outer surface of the nozzle at the outlet opening.
  • the nozzle has a flow element in which the second portion is tapered to a tip. In this way, the turbulence of the fuel is improved with the air flow at low pressure drop.
  • the flow element in the first section has a first radius of curvature.
  • a symmetrical and targeted guidance of the fuel is achieved. Due to the first radius of curvature, the fuel is deflected radially outward with a relatively small pressure drop from its longitudinal flow parallel to the longitudinal axis of the channel of the nozzle. However, the deflection occurs in such a way that a small pressure drop occurs.
  • a transition region between the first and the second section of the end piece has a second radius of curvature. In this way, a defined, but in the flow direction continuously extending tear zone for the fuel flow. This feature also prevents the occurrence of a large pressure drop.

  • a flow molding has a pin, at the end of which the flow element is formed, the pin having a constant cylindrical cross section in the channel at least in one end region in front of the outlet opening.
  • the pin has a constant cylindrical cross section substantially in the channel.
  • the pin is fastened to the nozzle via a fastening part.
  • the pin may be formed as a separate component and be positively or non-positively attached to the nozzle. In this way it is possible to retrofit existing nozzles with the pen.
  • the pin is connected to one or two struts with an annular or partially annular fastening part. Due to the design of the struts only a small area of the channel is blocked by the struts, so that only a slight turbulence or a small pressure drop occurs in the region of the fastening part.
  • the nozzle has a surface which is rotationally symmetrical to the center axis of the nozzle in the region of the outlet opening and tapers in the direction of the outlet opening of the channel. In this way, an efficient guidance of the air flow is achieved.
