Definitions
- the invention relates to a gas burner for a boiler according to the Preamble of claims 1 and 3.
- Such a gas burner is known from DE 92 05 202 U1.
- This atmospheric burner projects the gas nozzle into the mouth of the Burner tube so that air flows into the burner tube (Primary air) is sucked in by reduced injector action. It there is a dependency on the intake air volume flow from the gas flow. This dependency is not common to everyone Gas burners wanted.
- the injector is one Gas nozzle associated with a main nozzle bore as well as at least has a secondary nozzle bore which is at an angle to the axis of the Injector is aligned.
- the main nozzle bore is between an open and a closed position movable Closure element assigned, so that an operation with low Gas quantity with unchanged gas pressure above the inclined Secondary nozzle bore with reduced primary air content is possible.
- DE 44 33 425 A1 describes a control device for a gas burner described.
- a control circuit controls the speed of one air-promoting blower depending on the combustion. Of the Structure of the burner is not shown in detail.
- the object of the invention is a gas burner of the generic type To create at the gas nozzle at gas pressure changes as a result changed gas quality of the primary air portion largely remains unaffected.
- the Burner tube 1 with the longitudinal axis A has a conical downstream tapering mouth 5 and 6 flame openings 7 in a combustion chamber on.
- a heat exchanger 8 is arranged in the combustion chamber 6.
- Of the Combustion chamber 6 is connected to an exhaust pipe 9. Over the estuary 5 primary air Vp flows into the burner tube 1. Secondary air Vs can due to the thermal buoyancy in the combustion chamber 6 in these occur (see Fig. 5).
- a burner is included fan-assisted combustion is provided.
- One in the flame area arranged ionization electrode 14 detects that of the air ratio (lambda) corresponding to the respective gas-air mixture Combustion temperature.
- the control circuit derives from the air ratio and a control deviation from an air ratio setpoint and controls with a a gas valve located in the gas line 2 15 modulating. A rule deviation arises when the Fan speed or a change in gas quality.
- the Control circuit 13 is intended to achieve the target air ratio required amount of fuel gas depending on the heat demand Adjust the controlled air volume.
- the gas nozzle 4 (see. Fig. 2 to 4) is therefore arranged so that it protrudes coaxially to the longitudinal axis A into the burner tube 1, up to just above the end 5 'of the conical taper of the mouth 5 out.
- the gas nozzle 4 has on its circumference, ie radially to Longitudinal axis A, distributes several gas openings 16. These are in the Burner tube 1 further inside (to the right in Fig. 2) than the inner end 5 'of the mouth 5.
- the gas nozzle 4 points axially to the longitudinal axis A. No gas opening towards.
- On an external thread 17 is the Gas nozzle 4 into the gas distributor 3 by means of a hexagon attachment 18 screwable.
- the arrangement of the gas nozzle 4 and the position of the gas openings 16 is largely avoided that through the gas openings 16 in the Burner tube 1 entering gas an air-sucking injector effect unfolded. This ensures that the burner tube 1 Air volume supplied predominantly only from the speed of the Blower 12 and not from that prevailing in the gas nozzle 4 Gas pressure or the respective gas volume flow depends.
- the gas burner works with a controller 19 to which the Combustion-sensing ionization electrode 14 is connected.
- the Controller 19 controls the gas valve 15, for example the solenoid valve, and the gas pressure PA prevailing at the gas nozzle 4 accordingly the combustion.
- the gas valve 15 for example the solenoid valve
- PA gas pressure
- the gas nozzle 4 (see FIG. 6) has a jacket body 20 and an inner one in the jacket body 20 movable nozzle part 21.
- the nozzle part 21 is mounted in the jacket body 20 in the longitudinal direction A and by means of a compression spring 22 against the gas flow direction a, in Direction b, loaded.
- the nozzle part 21 has inside of the jacket body 20 on a conical extension 24, which is too a tubular gas channel 25 forming the gas opening 23 is narrowed.
- the casing body 20 forms a stop for a constriction 26 a movement of the nozzle part 21 in direction a, against the direction b.
- the gas openings 16 radial to the longitudinal axis A are on the jacket body 20 trained. They are within the conical mouth 5 of the Burner tube 1.
- the extension 24 of the nozzle part 21 forms an edge 27, which closes the gas openings 16 when the nozzle part 21 of the Compression spring 22 is displaced in direction b against a stop 28.
- the mode of operation of the gas nozzle according to FIG. 6 is approximately as follows:
- the compression spring 22 presses the nozzle part 21 against the stop 28 so that the radial gas openings 16 are closed and gas only through the axial gas opening 23 in the Burner tube 1 can occur.
- This gas flow leads to one Injection effect, by means of the primary air Vp into the burner tube 1 is sucked in. With an increasing gas pressure PA this becomes Nozzle part 21 shifted in direction a, the radial Gas openings 16 become free and now through this gas in the Burner tube 1 flows. This gas fraction essentially produces no injector effect, so that the primary air volume sucked in practically not increased.
