Definitions
- the invention relates to a control device for gas burners according to the preamble of claim 1.
- Control devices for gas burners are used to provide a gas / air mixture, that is to say to supply a gas stream and a ner combustion air stream to a burner.
- the gas flow through a gas valve is adjustable depending on the ner combustion air pressure.
- Such control devices are known from DE 24 27 819 B2, AT-PS 190 195 and DE 37 07 883 Cl.
- the present invention is based on the problem of creating a regulating device for gas burners which avoids the above disadvantages and thus has a larger area of application.
- Fig. 1 shows a control device according to the invention with further assemblies in a schematic representation.
- the control device shown in the drawing is used to provide a gas / air mixture for a gas burner, not shown.
- a gas flow can be fed to the burner (not shown) via a first line 10.
- a gas control valve 11 and two gas safety valves 12, 13 are assigned to the first line 10 carrying the gas flow.
- the gas control valve 11 and the gas safety valves 12, 13 can be configured in any way.
- the structure and mode of operation of gas safety valves and gas control valves are well known from the prior art.
- a ner combustion air flow can also be fed to the burner (not shown) via a second line 14.
- the ner combustion air flow is generated by a blower 15, the speed of which is determined by a motor 16 assigned to the blower 15.
- a diaphragm or throttle point 17 is arranged within the second line 14 carrying the ner combustion air flow.
- the first line 10 carrying the gas flow opens into the second line 14 carrying the air flow.
- the first line 10 carrying the gas flow is closed by a gas nozzle 18.
- a sensor 19 is arranged between the first line 10 carrying the gas flow and the second line 14 carrying the ner combustion air flow. With a first measuring point 20, the sensor 19 is connected to the first line 10 carrying the gas flow, namely in the flow direction of the gas in front of the gas nozzle 18. With a second measuring point 21, the sensor 19 is also connected to the second line 14 carrying the ner combustion air flow, namely in the direction of flow of the ner combustion air before the throttle point 17.
- the sensor 19 is designed as a differential pressure sensor, in particular as a flow meter or anemometer. With the aid of the sensor 19, the pressure difference between the gas pressure and the combustion air pressure can accordingly be determined. In the case in which the gas pressure coincides with the combustion air, the flow through the sensor 19 designed as a flow meter or anemometer is zero. If the combustion air pressure is higher than the gas pressure, a flow from the second measuring point 21 in the direction of the first measuring point 20 can be detected. On the other hand, in the case of a combustion air pressure that is lower than the gas pressure, a flow from the first measuring point 20 in the direction of the second measuring point 21 can be detected by the sensor 19. The pressure ratios of gas pressure and combustion air pressure through sensor 19 can accordingly be determined from the amount of flow through sensor 19 and the flow direction.
- the senor 19 Depending on these pressure conditions, the sensor 19 generates an electrical or electronic signal 22.
- This electrical or electronic signal 22 is fed to a control device or control device 23, which generates a control signal 24 for an actuator 25 of the gas control valve 11.
- the electrical or electronic signal 22 of the sensor 19 is offset in a summing device 26 with an auxiliary signal 27, specifically before the signal 22 is fed to the control device 23.
- the control device 23 is accordingly supplied with the output signal 30 of the summing device 26 as an input signal, the output signal 30 being an additive superimposition of the signals 22, 27.
- a factor can be determined in the evaluation device 28, which determines the transmission ratio between gas flow and combustion air flow. This factor is a multiplication factor. The higher this multiplication factor, the higher the gear ratio. The transmission ratio can be varied by varying the multiplication factor.
