Definitions

  • the invention relates to a safety arrangement for a burner connected to a fuel line connected and controlled by a burner control, with two valves arranged one behind the other in the fuel line and with actuators are provided, a pressure sensor for detecting the pressure between the Valves, at least one leak test device connected to the pressure sensor and the actuators for the valves are connected and at least one fuel test unit, to the burner control and to the upstream in the direction of flow Valve is connected.
  • the leak test unit and the fuel test unit are circuits that meet the requirements the DIN standards for fail safety are sufficient.
  • the leak test unit is used to check the tightness of the two valves.
  • a suitable program sequence checks the tightness of the valves by means of time measurement the pressure drop or increase within certain test times after a short period Open individual valves and calculate and check the maximum allowable Leakage rate at these valves. Such a method is described in DE 37 08 471.
  • the fuel test unit is used in the burner control when there is a heat request only release the program sequence at the start of the burner when a Sensor reports the presence of fuel.
  • the fuel test unit effects a shutdown of the burner if the signal during operation of the sensor fails. With the presence of the fuel, an automatic Allows the burner to restart. In addition, if there is insufficient Fuel pressure prevents a possible pollutant-rich combustion.
  • the invention is therefore based on the object of simpler and less expensive To create security arrangement.
  • the safety arrangement mentioned at the outset is according to the invention characterized in that the fuel test unit to the pressure sensor the leak test unit is connected.
  • the output signal of the pressure sensor is therefore used several times by not only used for the leak test unit, but also for the fuel test unit the relevant requirements of the DIN standards are met.
  • a fuel gas line 1 leads to a gas burner 2 by a burner control 3 is controlled.
  • two valves 4 are arranged, each having an actuator 5.
  • a pressure sensor 6 which detects the pressure in the fuel gas line 1 recorded.
  • the pressure sensor 6 is connected to a leak test unit 7, which in turn is connected to the Actuators 5 for the valves 4 is connected.
  • the safety arrangement further comprises a fuel test unit 8 which is connected to the burner control 3 and connected to the pressure sensor 6.
  • the signal of the pressure sensor 6 is thus used several times, and specifically at different ones Operating states.
  • the burner control 3 turns on Commissioning program continued. If the pressure sensor 6 reports no signal the inlet valve 4 is opened for a short time in order to reduce the fuel pressure to the sensor. If the pressure sensor 6 still reports no signal, is the inlet valve 4 is closed again and the electric burner control starts a suitable time delay to this program section after this Repeat time cyclically.
  • the leak test unit 8 can after the fuel shortage check before the burner start or be activated after the burner has run.
  • the pressure sensor can also be designed as a pressure switch.
  • the control of the gas burner as well as the tests for leaks and for the presence of fuel can be from a single control unit in the form of a microprocessor with the associated Circuits are carried out.
