Definitions

  • the invention relates to a control device for gas burners according to the preamble of claim 1.
  • a control device for gas burners for providing a gas / air mixture for providing a gas / air mixture, namely for supplying a gas flow and a combustion air flow to a gas burner, known.
  • a gas flow guided in a gas line is mixed with an air flow guided in a combustion air line so as to provide the gas / air mixture to be supplied to the gas burner, this mixture of the gas flow with the combustion air flow taking place in a mixing device passing therethrough is provided that the gas line opens with a gas nozzle within the combustion air duct downstream of a built-in combustion air duct throttling.
  • the thus provided gas / air mixture can be supplied to the gas burner with a blower.
  • the invention is based on the problem of creating a novel control device for gas burners. This problem is solved by a control device for gas burner with the features of claim 1.
  • the measuring point with which the sensor acts on the gas line is positioned directly adjacent to a gas nozzle with which the gas line opens into the mixing device.
  • the measuring point with which the sensor acts on the gas line is positioned directly adjacent to the gas nozzle, with which the gas line opens into the mixing device. According to the invention, therefore, the gas pressure is measured immediately adjacent to the gas nozzle and thus mixing device, so that pressure losses in the gas line, which connects the gas valve with the mixing device, are automatically compensated.
  • the electrical or electronic sensor can thus provide a more accurate measurement signal in the control device according to the invention, whereby the control accuracy for the gas valve and thus for the gas / air mixture can be increased.
  • Fig. 1 shows a block diagram of a control device according to the invention for a gas burner, by means of which a gas / air mixture can be provided and fed to a gas burner, not shown.
  • the control device comprises at least one gas valve 11 positioned in a gas line 10 in order to supply a gas flow to a mixing device 12, in which the gas flow supplied via the gas line 10 to the mixing device 12 can be mixed with an air flow supplied via a combustion air line 13.
  • the gas / air mixture provided in the mixing device 12 can be supplied via a blower 14 to a gas burner (not shown).
  • the mixing device 12 comprises a Venturi nozzle, which is integrated in a housing of the mixing device 12.
  • the gas line 10 opens with a gas nozzle 15 in the Venturi nozzle of the mixing device 12, namely in the region of the Venturi nozzle, in which it has approximately the narrowest flow cross-section.
  • the control device further comprises an electrical or electronic sensor 16 which engages with a measuring point 17 on the gas line 10 and at this measuring point 17 picks up the pressure prevailing in the gas line 10 gas pressure.
  • a reference point 18 of the sensor 16 there is a reference pressure, which preferably corresponds to the combustion air pressure.
  • the electrical or electronic sensor 16 provides an electrical or electronic measurement signal 19, which in the embodiment shown the Fig. 1 is charged with an output signal 20 of the blower 14 associated evaluation device 21.
  • the evaluation device 21 is supplied as an input signal 22, a speed signal of the blower 14.
  • a signal 23 formed from the measurement signal 19 of the sensor 16 and the output signal 20 of the evaluation device 21 is used in a control device 24 in order to generate a control signal 25 for an actuator 26 of the gas valve 11.
  • the measuring point 17, with which the electrical or electronic sensor 16 acts on the gas line 10 positioned immediately adjacent to the gas nozzle 15 and thus to the discharge point of the gas line 10 in the mixing device 12.
  • the prevailing in the gas line 10 gas pressure is therefore detected immediately adjacent to the gas nozzle 15 and thus immediately adjacent to the mouth of the gas line 10 in the mixing device 12 so that pressure losses within the gas line 10 are automatically compensated and have no negative impact on the achievable control accuracy.
  • the electric or electronic sensor 16 is associated with a filter 27 which is connected between the sensor 16 and the reference point 18 thereof. Via the filter 27 contamination of the sensor 16 can be avoided and the measurement accuracy of the same and thus ultimately the control accuracy of the control device can be increased.
  • the venturi nozzle of the mixing device 12 is preferably integrated in a housing thereof, wherein the housing and the venturi nozzle of the mixing device 12 preferably form a monolithic unit.
  • the gas line 10 engages with the gas nozzle 15 and the blower 14 at.
  • the sensor 16 is integrated with the filter 27 in the housing of the mixing device 12.
  • the sensor 16 is preferably a flow meter or an anemometer.
