Definitions

  • the invention relates to a method for regulating a gas burner according to the preamble of claim 1.
  • the present invention is based on the problem of a method to create a gas burner that avoids the above disadvantages.
  • the present invention relates to control devices for gas burners. A not shown A gas / air mixture should be fed to the burner.
  • first line 10 In order to supply a gas flow to the burner (not shown), there is a first line 10 provided that leads the gas flow to the burner.
  • the first line 10 is a gas valve 11 assigned.
  • the combustion air is supplied to the burner (not shown) via a second line 12.
  • the second line 12 consequently carries the Combustion air flow to the burner.
  • the second line 12 is a blower 13 assigned. The speed of the fan 13 determines the combustion air pressure and thus the combustion air flow.
  • Within the second leading the combustion air flow Line 12 has an orifice or throttle 14
  • the first line 10 leading the gas flow opens into Flow direction of the combustion air behind the throttle 14 in the Combustion air flow leading second line 12.
  • a gas nozzle 15 closes the first Line 10 in the area of the second line 12. In the direction of flow behind the gas nozzle 15 is therefore a gas / air mixture.
  • a sensor 16 is arranged between the gas line carrying the first line 10 and the Combustion air flow leading second line 12, a sensor 16 is arranged.
  • the Sensor 16 is designed as a flow meter or anemometer. With a first Measuring point 17 is sensor 16 on first line 10 carrying the gas flow connected. With a second measuring point 18, the sensor 16 is at the Combustion air flow leading second line 12 connected. In the direction of flow of the gas, the first measuring point 17 is positioned in front of the gas nozzle 15. The second measuring point 18 is arranged upstream of the throttle point 14 in the flow direction of the combustion air.
  • the sensor 16 generates an electrical or electronic signal 19, which is used to adjust the gas valve 11.
  • the electrical or electronic signal 19 is a control or Control device 20 supplied, the signal 19, a control signal 21 for the Actuator 22 assigned to gas valve 11 is generated.
  • the gas valve 11 is closed and the blower 13 switched off.
  • the flows through line 10 and Line 12 be zero and the sensor 16, which is designed as a flow meter, should be on Provide signal 19, which is also zero. In this case it can be correct working sensor 16 are closed and the actual control performed become. In this case, however, the sensor 16 supplies a signal 19 which deviates from zero, a faulty sensor must be concluded and the system is shut down.
  • the second line 12 leading the combustion air flow critical length e.g. opens into a chimney or a chimney, so despite switched off fan 13 a natural flow in the line 12 occur.
  • the Sensor security check would therefore result from this natural flow sensor 16 provide a non-zero signal 19.
  • the sensor security check would be his Do not accomplish the task.
  • a sensor 16 is assigned to the sensor security check Heater 23 turned off. The security check is then turned off Heating device performed.
  • Fig. 2 shows a highly schematic structure of the sensor designed as a flow meter 16. Between two temperature sensitive measuring devices 24 and 25, preferably are designed as PTC elements, the heating device 23 is arranged. Of the Signals provided to measuring devices 24 and 25 are sent to a comparator 26 supplied, which compares these signals with each other and ultimately the electrical or provides electronic signal 19. Resistor elements 27 and 28 shown in FIG. 2 serve to couple the measuring devices 24 and 25 to a corresponding one Power supply.
  • the invention relates to a method for regulating a gas burner.
  • a sensor designed as a flow meter For safety reasons, before a gas burner gas needs to heat can be supplied, a sensor designed as a flow meter a so-called Survive sensor security check. With this security check, those of Valves assigned to the gas line are closed and one of the combustion air line assigned fan is switched off. In this case it has to be from the flow meter measured signal be zero. Otherwise there is a defect in the flow meter closed and the system is shut down.
  • a heating device assigned to the sensor is switched off, and the Sensor security check is carried out with the heating device switched off.
