Definitions

  • the invention relates to a control device for gas burners according to the preamble of claim 1.
  • a control device is known from the summary of JP 600 800 18.
  • Control devices for gas burners are used to provide a gas / air mixture, that is to say to supply a gas flow and a combustion air flow to a burner.
  • the gas flow through a gas valve is adjustable depending on the combustion air pressure.
  • Such control devices are known from DE 24 27 819 B2, AT-PS 190 195 and DE 37 07 883 C1.
  • Control devices for gas burners are known in which the transmission ratio between gas pressure and combustion air pressure or between gas flow and combustion air flow is variable.
  • the required pressure measurement is carried out with the aid of a membrane, that is to say pneumatically.
  • this pneumatic route has a number of disadvantages, all of which limit the scope of known control devices.
  • the hysteresis properties of the membrane and the forces acting between the membrane and the gas valve limit the working area and thus the area of application.
  • the interaction between the required small actuating forces and the operating tolerances of the membrane as a result of disturbing influences such as temperature fluctuations or the like results in a restriction of the range of use of known control devices.
  • 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.
  • 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 combustion air flow can also be fed to the burner (not shown) via a second line 14.
  • the combustion air flow is generated by a fan 15, the speed of which is determined by a motor 16 assigned to the fan 15.
  • An orifice or throttle point 17 is arranged within the second line 14 carrying the 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 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 direction of flow 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 combustion air flow, namely in the flow direction of the combustion air in front of the throttle point 17.
  • the sensor 19 is designed as a differential pressure sensor, in particular as a flow meter or anemometer. With the help of the sensor 19, the pressure difference between the gas pressure and the combustion air pressure can therefore be determined.
  • 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 which 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 supplied to the control device 23.
  • the control unit 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.
  • the auxiliary signal 27 is a signal which is functionally dependent on a speed of the fan 15.
  • the auxiliary signal 27 is obtained in an evaluation device 28 from a speed signal 29 of the fan 15 or the motor 16 of the fan 15. Since the auxiliary signal 27 is functionally dependent on the speed of the fan 15, it follows immediately that the auxiliary signal 27 is dependent on the combustion air flow or combustion air pressure.
  • auxiliary signal 27 it is possible to generate the auxiliary signal 27 in a different way. It is therefore not absolutely necessary for the auxiliary signal 27 to be determined on the basis of the speed of the fan. It is also conceivable to provide an additional sensor, not shown, for determining the combustion air flow and thus for generating the auxiliary signal 27.
  • an electrical or electronic signal 22 is determined, which corresponds to the pressure difference between the gas pressure and the combustion air pressure.
  • This electrical or electronic signal 22 is offset against an auxiliary signal 27.
  • the electrical or electronic signal 22 and the auxiliary signal 27 are added.
  • the auxiliary signal 27 depends on the combustion air flow, in particular on the speed of the fan 15.
  • the output signal 30 of the summing device 26 determined from the signals 22, 27 is fed to a control device 23, which generates a control signal 24 for the actuator 25 of the gas control valve 11.
  • the control signal 24 is determined in such a way that the control device 23 changes the gas flow in such a way that the input signal for the control device 23, that is to say the signal 30 determined from the signals 22, 27, assumes an amount of zero.
  • 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.
