Definitions

  • the invention relates to a device for controlling a burner, in particular one Oil burner, according to the preamble of claim 1. Furthermore, the invention relates a method for controlling a burner, in particular an oil burner, according to the Preamble of claim 5.
  • the present invention relates to the field of burner technology.
  • Devices for Controlling a burner must have different aggregates of the burner, such as one Ignition device, an engine of a combustion air blower and fuel valves, in Depending on the operating status of the burner and depending on possible Activate or switch on and / or switch off fault states at the correct time.
  • the possible fault conditions include a so-called flame cut. Under A flame cut is to be understood that during regular burner operation, a Burner flame extinguished due to interference.
  • These interferences can Oil burners, among other things, that there is air in the oil line, that the fuel - So the oil - is only incompletely burned or that the oil due to exposure to cold gummed.
  • the burner flame is controlled by a flame monitoring device supervised.
  • the present invention is based on the problem, one Apparatus and a method for controlling a burner, both the Requirement of sufficient security as well as the requirement of adequate Availability is sufficient.
  • the above-mentioned device for controlling a Brenner developed by the features of the characterizing part of claim 1.
  • the method according to the invention has the features of claim 5.
  • the device shown in the drawing is used to control an oil burner Warm air heaters without oil preheating. It goes without saying. that the Device according to the invention also in connection with oil burners Oil preheating can be used.
  • connection elements 1, 2, 3, 4, 5, 6, 7, 8 and 9 for the connection of in particular Burner units.
  • the connection elements 1, 2 serve to connect one Flame monitoring device 10.
  • connection element 3 Ignition device 11 and to the connecting element 4 a motor 12 no further shown combustion air blower connected.
  • At the connection elements 5, 6 is each a fuel valve 13, 14 connected.
  • the connecting element 7 serves the Connection of an (external) fault indicator 15.
  • the connection element 8 is the Device according to the invention together with the units 11, 12, 13, 14 and 15 a neutral conductor 16 and via the connecting element 9 to a phase conductor 17 electrical network connected.
  • the flame monitoring device 10 connected to the connection elements 1, 2 monitors the burner flame of the burner.
  • the signals obtained here are over a flame amplifier 23 is supplied to a microcontroller 24.
  • the microcontroller 24 controls, among other things, in dependence on those by the flame monitoring device 10 provided signals the ignition device 11, the engine 12 of the combustion air blower, the fuel valves 13, 14 and the fault indicator 15 of the Brenners.
  • the device according to the invention has switches.
  • the switches are designed as relays in the embodiment shown. Each relay includes a contact 25, 26, 27, 28 and one of the respective contacts 25, 26, 27, 28 assigned coil 29, 30, 31, 32.
  • the contact 25 and the coil 29 accordingly form one Relay or a switch.
  • a reset device 33 In addition to the elements of the device according to the invention already mentioned shows 2 a reset device 33, a Monitoring device 34 for the microcontroller 24, an oscillator 35 Memory device (EEPROM) 36, a system 37 for fault display or information display, Systems 38, 39, 40 for line voltage monitoring, supply monitoring and supply and an internal suppressor / interlock switch 41.
  • EEPROM Electrically erasable programmable read-only memory
  • the switches of the device according to the invention are such controllable that the motor 12 of the Combustion air blower switched on, the ignition device 11 for igniting the Burner flame switched on and off and the fuel valves 13, 14 opened.
  • the engine 12 of the combustion air blower and the Ignition device 11 switched on to ignite the burner flame.
  • a first fuel valve 13 opened so that the fuel in the combustion chamber of the Burner is introduced and a burner flame is formed.
  • the Flame monitoring device 10 reports the presence of the flame via the Flame amplifier 23 to the microcontroller 24.
  • the ignition device 11 is switched off and on Another fuel valve 14 opened, ensuring full fuel supply becomes.
  • the switches can be controlled in such a way that the engine 12 of the combustion air blower is switched on and the ignition device 11 and the fuel valves 13, 14 are switched off.
  • the engine active 12 and passive ignition device 11 of the unburned fuel from the combustion chamber blown out of the burner ensures that there is no unburned Can ignite fuel and also none before restarting the burner unburned fuel is in the combustion chamber.
  • possibly glowing parts of the combustion chamber cooled down. This makes security significant elevated.
  • the switching duration of the switch position for re-venting the burner is adjustable.
  • the post-ventilation is preferably carried out over a period of 60 seconds.
  • the burner is started again immediately after the post-ventilation.
  • the switches can be controlled in such a way that the motor 12 of the combustion air blower, the ignition device 11 and the fuel valves 13, 14 are switched on.
  • the burner is restarted in the same way as the startup described above the same. It can therefore be referred to the above statements.
  • the invention is therefore based on the idea immediately after the occurrence of a The flame breaks off and before the burner is restarted, the ventilation is re-vented To carry out the burner.
  • the switch assigned to the ignition device 11 or Relay opened.
  • the coil 29 of the relay therefore holds the contact 25 in the open Position.
  • the switches or the fuel valves 13, 14 assigned to Relay open the coils 30, 31 accordingly keep the contacts 26, 27 in the open Position.
  • the switch (or relay) comprising coil 32 and contact 28 is in a position in which the motor 12 is switched on.
  • the contact 25 is re-vented via the coil 29 of the relay or switch closed.
  • the ignition device 11 is therefore active.
  • the contact 26 for switching on the first is via the coil 30
  • Fuel valve 13 closed When a burner flame is formed, this is done by the flame monitoring device 10 is detected and the microcontroller 24 reported. After a certain time, the contact 25 is opened and the ignition device 11 switched off. Furthermore, the contact 27 is closed and thus the fuel valve 14 open. It is therefore switched to a higher burning power.
