Definitions

  • the invention relates to a method according to the preamble of claim 1 and an apparatus for carrying out the method.
  • Atmospheric gas burners without air number adjustment are generally designed for intermittent operation, wherein the sizes of the fuel and air flow are determined in response to a power request signal so that the respective desired performance is provided.
  • the power request signal can be generated by a temperature controller, for example.
  • the air volume flow intended for the combustion is here in general not continuously tracked, i. that the amount of air is approximately constant and is usually designed for the maximum burner output.
  • the air volume flow can be monitored, for example by means of a pressure switch.
  • the pressure switch can be switched parallel to an air resistance in the air duct.
  • the pressure switch measures the pressure difference across the air resistance and thus the air flow in the channel.
  • the pressure switch thus functions as an air flow tester whose contacts are closed with sufficient air flow. It is important that the pressure switch works reliably and failsafe.
  • the publication DE-A1-4429157 shows the monitoring of a generally applicable regulation.
  • the signal change of the control sensor is monitored as a result of a controlled, fixed change of an actuator in the control loop.
  • EP-A-909 922 discloses a combustion chamber with an air pressure sensor therein, the signal of which is a measure of the aeration.
  • the sensor signal is regulated down to a desired signal, which is generated by a higher-level flame quality control by means of measurement on an ionization electrode.
  • the flame quality control based on the ionization electrode could determine the resulting deviation of the air ratio and adapt the desired signal in accordance with an optimization of the flame quality.
  • the settings of the flame quality control would indirectly depend on the sensor signal again, whereby any external influences could still affect the flame quality and air flow to a certain extent.
  • EP-A-1130320 discloses a method for testing the operation of a control system for a heating burner in which the vacuum in the combustion chamber is monitored by a differential pressure switch.
  • the invention is therefore based on the object without monitoring the flame signal or the fan speed to allow a reliable and accurate verification of the function of the control / regulation system in a heating burner.
  • the method according to the invention is based on putting the air control loop into operation before the actual burner start-up in which a control setpoint is set which is at least the maximum value or the maximum value of the normal operating range of the burner.
  • the resulting control result e.g. the adjusting volumetric flow size is queried by means of a differential pressure switch and evaluated for correctness. Only when this check has taken place, the burner is released for normal operation.
  • all components of the control loop can be checked in a simple manner during start-up of the burner with regard to their perfect function.
  • the phase control of the fan, the blower itself, the pressure sensor, the modulator stage, for example, designed as a gas actuator and the pressure switch may be mentioned here.
  • the switch-off point of the pressure switch should preferably be above the chimney draft maximally adjusting air volume flow.
  • the proper function of the pressure switch is checked by the rest position (pressure switch off) is detected before the air control loop, i. the fan is switched on. If the pressure switch is not in the idle position, the blower is switched on and the burner remains out of operation.
  • the single figure shows schematically an atmospheric gas burner with a combustion chamber 1, in which a blower 2 is arranged.
  • An air adjusting signal 3 controls the speed of the fan drive via an air actuator 4 and thus influences the air volume flow in an exhaust duct 5.
  • an air resistance 6, e.g. in the form of a throttle member, as well as upstream or downstream of the throttle member pressure relief points are provided, which are connected to a pressure sensor 8 and an air flow tester, for example in the form of a pressure switch 7, which is connected in parallel to the pressure sensor 8.
  • the pressure switch 7 generates an air test signal 9 and the pressure sensor 8 an air sensor signal 10th
  • the air test signal 9 and the air sensor signal 10 are fed to a control device 11 which generates therefrom the air control signal 3 for the blower 2 and a fuel control signal 12 for the fuel actuator 14.
  • the fuel actuator 14 controls the fuel flow in a gas line 13 by means of a modulated gas valve 15.
  • the control device 11 can generate an enable signal 16, which opens a safety valve 17 in the gas line 13.
  • the control device 11 generates the release signal 16, for example by means of a safety device 21, e.g. may be included in an automatic burner, not shown.
  • the monitoring of the air volume flow according to the invention takes place each time the burner is started up.
  • the safety device 21 before release of the fuel, the safety device 21 generates a control setpoint value 23 which, for example, amounts to 120% of the maximum air volume flow in normal operation of the burner.
  • the pressure switch 7 will close because of the pressure drop over the air resistance 6.
  • the safety device 21 compares the air test signal 9 with a reference value corresponding to the closed state of the pressure switch 7. When the pressure switch is closed or turned on, this is detected by the safety device 21, whereby the test is completed and the burner can be released for operation.
  • the safety device 21 can monitor, after previous closure of the pressure switch 7, whether the pressure switch 7 opens again during the subsequent shutdown of the rotational speed of the blower 2. As a result, the function of the pressure switch can be checked.
  • the control device 11 Only when the abovementioned processes proceed without errors does the control device 11 start an ignition method for starting up the burner.
  • the gas line 13 is released for a fuel flow.
  • the functional test is carried out before normal operation, ie before opening the valve 17 and only when the functional test is completed without errors, the fuel valve 17 is then opened, and the burner can then be moved to normal operation.
  • a power request signal 20 which may originate, for example, from a higher-level temperature controller, the safety device 21 to open the throttle valve 15 via the fuel control signal 12 accordingly.
  • the safety device 21 provides an air setpoint signal 23 via a correspondingly stored characteristic curve 22.
  • the air setpoint signal 23 is fed to an air regulator 24, which then adjusts the air sensor signal 10 by generating the air adjusting signal 3.
  • the air regulator 24 may perform PI / PID control.
  • a pump 18 then transports the water to be heated through a heat exchanger 19 arranged in the combustion chamber 1.
