Definitions

  • the invention relates to a fuel gas-air mixing device for a heater.
  • Generic mixing devices are based on a mixing nozzle, usually a venturi nozzle, in which air is conveyed through the nozzle by means of a blower.
  • a mixing nozzle usually a venturi nozzle
  • fuel gas is supplied orthogonally.
  • a throttle in the gas path the amount of fuel gas required for clean combustion is adjusted in relation to the amount of air.
  • the venturi ensures that over a certain range of air mass flow, the fuel gas to air ratio remains constant within close tolerances.
  • the patent application DE 196 35 974 A1 describes a fuel gas-air mixing device for gas heaters, in which the opening cross section is adapted to the combustion chamber by a gravity-loaded pendulum flap depending on the volume flow.
  • the patent EP 1 183 483 B1 describes a mixing device for fuel gas and combustion air with two parallel air nozzles in the form of Venturi nozzles.
  • One or alternatively both air nozzles can be switched off by means of shut-off devices.
  • the shut-off devices are designed as flaps, wherein the flaps are held by springs against the flow direction. The spring rate thus determines the Absperr characterizing.
  • the mixing devices known from the prior art have the disadvantage that the relationship determined by the geometry between air volume and pressure loss in the narrow cross section can be changed only abruptly, but not continuously. Even in the case of a steady opening of the shut-off device in one of the air nozzles, the pressure signal which is decisive for the gas injection remains exclusively dependent on the existing, unchangeable nozzle geometry. Furthermore, the introduction of gravity or spring-loaded shut-off devices in the flow path causes control tolerances, which is due on the one hand to unfavorable flow conditions and on the other hand to the sensitivity of the pressure loss to component tolerances.
  • the goal is to operate with a Venturi principle Pneumatic gas-air composite in part-load operation to generate a sufficiently large pressure signal to ensure accurate control of the gas valve.
  • the flow path of the air supply is designed so that it is designed without interference and without edges or sheets, where turbulence.
  • a continuous change of the cross section depending on the air mass flow is provided. This is done on the one hand by a flow-favorable design of the throttle means, on the other hand by the possibility that throttle means and air duct move continuously to each other.
  • the direction of the displacement is parallel to the direction of air flow, so that this shift can be effected simply by air pressure differences before and after the mixing device.
  • the displaceable throttle means or the slidable air duct coupled with a separate valve for fuel gas, that this is opened simultaneously with the opening of the air duct displacement of the throttle means or air duct continuously and in proportion to the change in cross section of the air duct. This ensures that at each operating point of the mixing device, the air / fuel gas ratio corresponds to a predetermined value.
  • the aerodynamic design is ensured by an advantageous length / diameter ratio.
  • the term diameter should not be limited to circular cross-sections, but rather be applicable to any cross-sectional shape.
  • the throttle means on continuous cross-sectional transitions. For an undisturbed flow along the throttle means is possible.
  • the mixing device is preferably designed so that the flowing air and thus the acting air pressure of the composite shifts the air duct and / or the throttle means against an elastic element in the air flow direction.
  • the elastic element defines a force-distance relationship.
  • the design of the air channel, the throttle means and the elastic element are adapted so that increases continuously with increasing air mass flow, the cross-sectional area formed between the throttle means and the air duct. This ensures that the minimum flow velocity required for the reliable functioning of the mixing device is present in a wide range for the air mass flow and thus there is a sufficiently high negative pressure for a function of the mixing device.
  • the elastic element is a spring.
  • the air channel is stationary and the throttle means slidably executed.
  • the throttle means is connected to a spring-loaded lever which is so long that the throttle means along an approximately linear locus is movable parallel to the air flow direction.
  • the throttle means is stationary and the air duct slidably executed.
  • the air duct is displaceably guided linearly against a spring.
  • FIG. 1 shows a name of a mixing device according to the invention.
  • blower air is conveyed through the venturi.
  • the Venturi nozzle is formed from the air duct 2 and the throttle means 3 contained therein. Seen from the left, the free cross-section for the air flow decreases continuously to a cross-sectional constriction 4, after which it widens again.
  • a feed 5 is provided for fuel gas. Due to the higher flow velocity within the cross-sectional constriction, a negative pressure is formed so that fuel 5 is conveyed through the feed 5 into the air path and mixes with the air. With the help of the speed of the blower, not shown here, the amount of the gas-air mixture can be changed.
  • the mixing ratio between fuel gas and air remains constant in a certain range. If the speed of the fan and thus the mass flow of the air is reduced even further, it is no longer possible to ensure that the mixing ratio remains constant. For this reason, the Venturi nozzle 1 is designed so that the air channel 2 and the throttle means 3 move due to the pressure conditions that set by the air flow, the way against each other can, that increases with high flow velocities, the free cross-sectional area between the air duct 2 and throttle means 3 or reduced with low flow velocities.
  • the feed 5 is connected to a valve 6, with which the mass flow of the supplied fuel gas is variable.
  • the valve 6 is connected to the air passage 2 so that the valve 6 is opened when the air passage 2 is shifted to the right.
  • the throttle means 3 has the shape of an ellipsoid of revolution.
  • the throttle means 3 is attached to a long lever so that it is guided along a circular path with a very large radius, which is approximately a straight line. With increasing air velocity, the throttle means is pressed against the spring 7 to the right.
  • the lever is connected to a valve 6, through which the fuel gas supply can be metered by the feed 5. With increasing air speed, the valve 6 is opened more and more, so that the fuel gas supply is adjusted to the amount of air.
