Definitions
- the invention relates to a mixing device for producing a mixture of gas and Combustion air for a burner according to the preamble of claim 1.
- Such a mixing device is from EP 0 559 280 A1 and essentially also known from EP 0 702 194 A1.
- it is a funnel-shaped widening Mixing chamber available, which on the side of the smaller diameter Combustion air is supplied and in which a control body without external drive is axially adjustable solely by the pressure difference generated fully by the flow.
- a control body without external drive is axially adjustable solely by the pressure difference generated fully by the flow.
- the Control body is in the case of EP 0 559 280 A1 in the flow path of the gas / air mixture and is equipped with an additional element that controls the gas flow.
- EP 0 702 194 A1 it each has one in the flow path of the combustion air and the gas lying on the valve body. So in both cases it is as Double throttle body designed.
- the object of the invention is to provide a generic mixing device which an extremely simple construction has a high efficiency.
- the mixing device characterized in claim 1.
- the flow resistance changes depending on the Throughput such that the throttle body is already a relative at low flows high flow resistance and a relatively low flow rate Has flow resistance.
- the pressure difference generated by the fan is at low throughput high. This results in high stability with low throughput as well as a low likelihood of burner noise different environmental conditions.
- the formation of the mixing device is from the arrangement of the fan largely independent. It can by airflow or the mixture flow or be arranged at the outlet of the combustion chamber.
- the outlet funnel 2 of a Venturi nozzle is sealed, the is surrounded on the outside by an annular chamber 3.
- This annular chamber 3 is formed between an essentially hollow cylindrical housing part 4 and the outer wall of the Exhaust funnel 2.
- the housing part 4 is also attached sealed to the support plate 1 and at its opposite end 5 as an inflow funnel 6 of the Venturi nozzle designed.
- the annular chamber 3 is above the interior 7 of the venturi nozzle circumferential annular gap 8 in connection.
- a throttle body 9 is vertical in the standing and upwardly open outlet funnel 2 freely floating axially. The respective position of the throttle body 9 is determined by the balance of forces, which results from the differential pressure generated by the flow at the throttle body 9 on the one hand and the throttle body weight on the other.
- the contiguous Parts of outlet funnel 2 and inflow funnel 6 together form the nozzle neck 10 of the Venturi nozzle.
- Combustion air A is fed to the inflow funnel 6, while the gas G via a Pre-throttle 11 passes from the inlet 12 into the annular chamber 3 and from there through the Annular gap 8 is sucked through by the air stream A.
- the gas G flows in the area of the Nozzle neck 10 approximately tangential to the air flow A in flowing through the Venturi nozzle the nozzle, which on the one hand leads to a good mixing of gas and air on the other hand, it does not adversely affect the reinforcing effect of the venturi nozzle.
- the degree of gain of the Venturi nozzle is defined as the ratio of the pressure difference the Venturi nozzle, measured between the inlet on the inflow funnel 6 and the gas supply point at the annular gap 8, and the pressure drop which the Venturi nozzle in the main stream, that is in the air flow.
- the mixture M of combustion air A and gas G leaves the venturi nozzle at its outlet 13.
- the throttle body 9 is by the Mixture flow kept floating and centered because of any radial shifts of the throttle body 9 to different pressure drops in the annular gap 14 between Throttle body 9 and outlet funnel 2 lead and thereby a radial displacement in the central location.
- the throttle body 9 by Guide means 15 can be guided displaceably in the axial direction.
- limiting means 16 the axial stroke of the Limit throttle body 9 in one or both directions.
- a blower which is either on the supply side A of the air or on the downstream side M of the mixture or downstream thereof at the outlet of the Combustion chamber can be arranged, a flow in the direction of arrows A and M. generated, which depends on the current blower output (speed).
- speed the current blower output
- the throttle body 9 for example in the extended shown position where the annular gap 14 between the throttle body 9 and the outlet funnel 2nd relatively low and consequently the flow resistance and thus also the pressure drop the throttle body 9 is relatively high.
- Throttle body 9 When there is a high demand for heat, the moves Throttle body 9 in the direction of the dashed position 9 ', where the annular gap 14 is larger and thus the flow resistance is lower. This leads to the one described above Stabilization of the flow in the area of low throughput.
- the gas supply With the pre-throttle 11 the gas supply is divided so that air and gas in a predetermined, optimal burning mixture ratio reach the burner. This gas / air ratio remains at all positions of the throttle body 9, i.e. same with changes in throughput.
- the throttle body 9 must be axially through the Guide means 15 are guided and biased in the closing direction by means of a spring, because then its weight no longer counteracts the flow pressure.
- the order and design of such guide means and a return spring is from EP 0702 194 A1 known.
- the guide means 15 can for example consist of several evenly distributed over the circumference of the inner wall of the outlet funnel 2, axially extending ribs exist, which, as indicated by dashed lines, at their lower end at the same time form a stop as a stroke limiting means 16 for the throttle body 9 can.
- Such guide means can also be full, as shown, with a vertical nozzle axis Be useful.
