Definitions

  • the invention relates to a method for flame monitoring in gas burners according to the preamble of claim 1. Furthermore, the invention relates to a device for Flame monitoring in gas burners according to the preamble of claim 5.
  • Proper and safe flame monitoring is essential for fault-free and making safe operation of gas burners essential.
  • pilot flame is the flame with the help of a flame monitoring device
  • the presence of the pilot light is monitored in order to depend on the actual one Control gas supply to the gas burner. If there is an ignition flame, the gas burner can Gas are supplied, which ignites with the help of the pilot flame and then burns. On the other hand, if there is no pilot flame, no gas may be supplied to the gas burner be otherwise a combustion of the gas would not be guaranteed and that unburned gas would jeopardize the safety of the entire facility.
  • the output signal of the Flame monitoring device not checked or verified. Delivers the Flame monitoring device accordingly an incorrect output signal - i.e. shows the output signal of the flame monitor the presence of the Pilot light on even though there is no pilot flame at all - this is how gas can reach the burner that would not burn and thus the safety of the entire system would endanger.
  • the present invention is based on the problem of a method and a method Flame monitoring device for gas burners to create a Ensure flame monitoring with higher security.
  • FIG. 1 schematically shows a gas burner 10, to which gas is supplied via a gas line 11 can be.
  • a gas line 11 can be.
  • two gas valves 12, 13 are arranged, which over corresponding actuators 14, 15 can be opened and closed.
  • the presence of the pilot flame 17 is checked by a flame monitoring device 20 monitors, the output signal 21 of a control device, not shown becomes. If the output signal 21 indicates the presence of the pilot flame 17, it can Via a second thermostat 22, a so-called control thermostat, the actuator 15 controlled and the gas valve 13 are opened. Then passes through the gas line 11 Gas to the gas burner 10, which is ignited by means of the pilot flame 17, and then for firing of the heat exchanger 18 provides. Via the control thermostat 22 Gas supply to the gas burner 10 is regulated such that e.g. a desired temperature in the Heat exchanger 18 is reached and held. Accordingly, the desired temperature exceeded in the heat exchanger 18, so by appropriate control of the Control thermostats 22 and thus the gas valve 13 are intervening regulating. Becomes the target temperature in the heat exchanger is exceeded, so it goes without saying Gas valve 13 closed. If the temperature falls below the set temperature, the opens Control thermostat (thermostat 22) the gas valve 13 again.
  • an additional sensor 23 designed as a temperature sensor is provided, the output signal 24 of the control device, not shown is fed.
  • the output signal 24 of the additional Sensor 23 together with the output signal 21 of the flame monitoring device 20 and an output signal 25 of the thermostat 22 processed. This can Output signal 21 of the flame monitoring device 20 continuously verified and there can be greater certainty of the presence or absence of it the pilot flame 17 and the actual main flame closed become.
  • the senor 23 is as Temperature sensor formed and assigned to the heat exchanger 18. That's the sensor 23 preferably assigned to a water pipe of the heat exchanger 18, it monitors therefore the temperature of the water inside or outside the heat exchanger 18th
  • the output signal 21 is thus the Flame monitoring device 20 verifiable. This is done immediately at Closing the control thermostat 22 or opening the gas valve 13, the temperature of the Water in the heat exchanger 18 measured and stored by the sensor 23. After a The predetermined time period of 1 minute, for example, is again from the sensor 23 Temperature measurement carried out. If no increase in temperature can then be determined, then the faulty behavior of the flame monitoring device 20 can be concluded. In in this case the gas valve 13 is then closed. The security of the entire system will be improved.
