Definitions
- the invention relates to a device for initiating Fuel gas in an air stream, especially for a gas premix burner, with a venturi tube pointing towards its Air flows through the pipe axis, and with at least one in the venturi leading inlet opening for the Fuel gas.
- the introduction of the fuel gas into the Air flow occurs approximately in the area of the narrowest cross section of the Venturi tube via a coaxial to the tube axis of the venturi arranged annular inflow opening.
- the from this annular inflow opening in the shape of a jacket around the Air gas escaping around the air stream essentially flows without mixing with the air flow on the diffuser wall of the Venturi tubes along.
- the actual mixing between Fuel gas and air only take place in a downstream of the Inflow opening or the venturi arranged fan.
- the present invention has the object based on an introduction device of the aforementioned Kind in such a way that a faster expansion of the diffuser or the Venturi tube is possible.
- this object is achieved by a swirl generation device, the at least the one immediately downstream the mixture flowing at least one inflow opening from air and fuel gas directed around the pipe axis Twist impresses.
- the at least one inflow opening provided that diagonally to the pipe axis in the direction of the inner wall of the venturi is directed.
- the mixture can flow at least downstream a slight swirl offset an inflow opening become.
- a negative pressure can be generated at the inflow opening, through which the fuel gas is sucked into the Venturi tube.
- the at least one inflow opening transverse to Pipe axis in the direction of the inner wall of the Venturi tube is directed. If necessary, the fuel gas flows in a certain pressure from the inflow opening.
- At least one inflow opening surrounding the air flow Ring opening is in advantageous developments.
- Fuel gas can e.g. due to one of the air already upstream of the swirl imposed likewise to be in a swirl.
- At least one guide surface inside the ring opening can also impart a swirl to the outflowing fuel gas become.
- the at least one guide surface can e.g. one between the two peripheral walls forming the ring opening provided guide vane.
- a twist generating at least one inflow opening is through an inflow pipe terminating within the venturi tube is formed.
- This development has the advantage that the outflow direction the fuel gas from the inflow pipe as desired can be adjusted.
- one forms in the Venturi tube protruding inflow pipe a flow chicane, which leads to eddies in the flow and thus to a contributes to better mixing of fuel gas and air.
- the swirl generator upstream of the Inflow opening provided for generating a swirl in the air.
- This swirl also creates a swirl downstream Mixture of fuel gas and air, the swirl effect e.g. due to a slightly tangential inflow of Fuel gas can be further amplified.
- At least one guide surface is provided for the air is.
- one or more vanes are provided for the air be.
- the at least downstream an inflow opening provided a radial fan is.
- the swirl of the mixture can flow to the radial fan be used to advantage. With counter-swirl flow a particularly high fan performance can be achieved, while a particularly low-loss in the case of constant swirl flow
- the mixture can enter the radial fan is.
- the inflow opening in the lies essentially centrally in the tube axis the lower pressure in the center of the circular flow is used become.
- FIG. 1 shows a gas premix burner with a gas boiler 1 and with a blower 2 , which is driven by a blower motor 3 and supplies an air / fuel gas mixture 4 to the gas boiler 1.
- the blower 2 is preceded by an introduction device 10 , in which fuel gas 5 is mixed with the air 6 sucked in by the blower 2.
- the introduction device 10 comprises a Venturi tube (Venturi nozzle or channel) 11 in which the air 6 is temporarily accelerated to a high speed.
- the fuel gas 5, which flows into the venturi tube 11, is sucked in through this air stream via an inflow opening 12 arranged in the region of the narrowest cross section of the venturi tube 11.
- the supply of the fuel gas 5 is regulated by means of a gas zero pressure regulator 7 .
- a swirl 15 directed about the pipe axis 14 is impressed on the mixture 4 flowing in the diffuser 13 of the venturi 11, so that a separation of the flow of the mixture 4 from the inner wall of the diffuser 13 is delayed or completely prevented.
- the swirl 15 can be generated either by a swirl impressed on the air 6 upstream of the inflow opening 12 or by a swirl impressed on the mixture 4 only downstream of the inflow opening 12.
- a first exemplary embodiment of an introduction device 10 in which the fuel gas 5 is introduced into the Venturi tube 11 via an inflow pipe 16 .
- the inflow pipe 16 is oriented obliquely to the pipe axis 14 on the inner wall of the venturi 11, so that the mixture 4 downstream of the inflow opening 12a of the inflow pipe 16 through the air 6 flowing in the direction of the pipe axis 14 and the fuel gas 5 flowing slightly tangentially into the venturi 11 Flows through diffuser 13 with a swirl 15.
- the inflow tube 16 is directed transversely to the tube axis 14 onto the inner wall of the venturi tube 11, so that the air 4 flowing in the direction of the tube axis 14 and the fuel gas 5 flowing transversely into the venturi tube 11 cause the mixture 4 downstream of the inflow opening 12b receives a swirl 15 in total in the diffuser 13.
- a swirl 17 is imparted to the air 6 before or during its entry into the venturi 11, which then continues as a swirl 15 of the mixture 4 within the diffuser 13.
- the fuel gas 5 flows from the inflow opening 12c parallel to the pipe axis 14 into the venturi tube 11.
- the fuel gas 5 ' is introduced into the Venturi tube 11' via an annular inflow opening 12 ' .
- a swirl to the air 6 ' upstream of the inflow opening 12' and / or by imparting a swirl to the fuel gas 5 ', as shown in FIG. 5, as it flows out of the annular inflow opening 12', this leads within the diffuser 13 ' to a swirl 15' of the mixture 4 'of air 6' and fuel gas 5 '.
- a device (10) for introducing fuel gas (5) into an air flow, especially for a gas premix burner with a Venturi tube (11) which is in the direction of its tube axis (14) of air (6) flows through, and with at least one in the Venturi tube (11) leading inflow opening (12) for the fuel gas (5) is provided with a swirl generating device, the at least that immediately downstream of the at least an inflow opening (12) flowing mixture (4) Air (6) and fuel gas (5) directed around the pipe axis (14) Imprints (15).
- This is a better and longer application of the mixture to the diffuser and thus one faster expansion of the diffuser or Venturi tube possible.
- the swirl of the flow continues to cause the air and the fuel gas are already in the diffuser mix better.
