Definitions

  • the invention relates to a device for initiating Fuel gas in an air stream, especially for a gas premix burner, with an inflow chamber for the air, with a leading into the inflow chamber for the Fuel gas and with a (first) swirl generating device, by means of the air flowing through the inflow chamber Swirl is impressed, the inflow opening in the Axis of the (first) swirl generating device is arranged.
  • Such a device is for example by DE 33 45 611 A1 has become known.
  • Introductory devices are also known in which the fuel gas metering after a pressure loss Throttle point is aimed.
  • the so-called “mechanical gas-air network” in order to change the performance, the flow cross-sections of air and fuel gas alike.
  • the so-called “Pneumatic compound” is the pressure of one fluid the pressure loss at the throttle point changed to the to achieve the same mixing ratio.
  • the so-called “Zero pressure control” is the pressure loss of the throttle point in the one fluid stream chosen approximately the same as the pressure loss of the throttle point in the other fluid flow, which makes the mixing ratio independent of the throughput becomes.
  • the usable performance range is also here small because of precise pressure control with small pressure differences is very difficult.
  • the present invention has the object based on an introductory device of the aforementioned Art in such a way that even better metering accuracy can be achieved.
  • this object is achieved by a further one (Second) swirl generating device, which through the inflow opening flowing fuel gas or one through the inflow opening already flowing mixture of air and fuel gas imbues a twist.
  • the further swirl generating device which by the inflow fuel gas flowing through the Inflow opening flowing mixture of air and fuel gas Swirl imprints can already be upstream of the inflow opening a swirl is imparted to the fuel gas or the mixture be the downstream swirl of air reinforced.
  • This is preferably a further swirl generating device upstream of the inflow opening for generation of a swirl only in the air of through the Inflow opening flowing mixture arranged.
  • the inflow opening is designed as a Venturi nozzle.
  • Fuel gas Due to the swirl of the rotating air flow is in the Inflow center arranged for the center of the swirl Fuel gas generates a high negative pressure, which regulates the pressure of the fuel gas to be introduced is significantly simplified and thus increasing the metering accuracy. This can already with a low pressure drop in the air a precise, adjustable Mixing ratio with the fuel gas in one large performance range can be achieved.
  • the generation of the Swirls in the air also have the advantage that the flow with changes of direction not so easily detachment shows and thereby space is saved can.
  • the swirl generating device preferably has at least one, in particular several evenly distributed around its circumference swirl-generating guide vanes.
  • Via adjustable Guide blades can also be the metering of Fuel gas or the mixing ratio between air and Influence fuel gas particularly easily.
  • Swirl generating device designed as a cyclone. It turns out turns out to be advantageous, a larger amount of fuel gas to flow in the center of the cyclone to avoid flow losses to reduce.
  • a radial fan is arranged downstream of the inflow chamber.
  • the twist of the mixture flowing out of the inflow chamber can be used for inflow of the radial fan can be used advantageously.
  • Counter-swirl flow can be a particularly high fan output can be achieved while a constant swirl flow particularly low-loss entry of the mixture into the radial fan is possible.
  • FIG. 1 10 'shows an introduction device for a gas premix burner (not shown) in which air 11, 11' and fuel gas 12 are mixed together and then fed to the gas premix burner as a mixture 13 .
  • the air 11 is sucked in via a peripheral opening 17 into an inflow chamber 18 via a radial fan 14 , which is driven by the motor 15 in the direction of rotation 16 .
  • guide vanes 19 (FIG. 2) are arranged, which form a cyclone and which impart a swirl 20 to the air 11 flowing through the inflow chamber 18, as is also indicated by the flow arrows 21 in FIG. 2.
  • an inflow opening 23 ' in the form of a Venturi nozzle 29 is provided, through which the fuel gas 12 and further air 11' are jointly introduced into the inflow chamber 18 in the direction of the axis of rotation 22.
  • the air 11 ' is sucked in via the radial fan 14 via an air duct 31 and into the Venturi nozzle 29, the air 11' entraining the fuel gas 12 via a nozzle-shaped inflow opening 32 arranged in the region of the axis of rotation 22.
  • a swirl 34 is impressed on the air 11 'upstream of the inflow opening 23' via guide plates 33 (FIG.
  • the mixture 25 of air 11, 11 'and fuel gas 12 in the radial fan 14 flows radially outward into an outer flow channel 24 and then out via an outlet opening 26 in the direction of the gas premix burner.
  • the swirl 35 and the direction of rotation 16 of the radial blower 14 are directed in the same direction, whereby a particularly low-loss entry of the mixture into the radial blower 14 is possible if the impeller 27 of the radial blower 14 is equipped with corresponding guide vanes 28 .
