Definitions

  • the invention is based on a method for operating a gas burner according to the preamble of the main claim.
  • the known method of this type is the pressure drop measured by the flow resistance in the combustion air duct, from this to the volume of the combustion air flow closed and accordingly on the gas actuator or the gas supply acted.
  • Changes in pressure and changes in volume flow in one quadratic relationship and stand for a desired Modulation range of the burner output of 10: 1 on Differential pressure range of 100: 1 would have to be detected.
  • this is especially true for devices with one mechanical linkage of air and fuel control today only up to a modulation range of approximately 4: 1 controlled.
  • the measures and means envisaged can be both downstream of the Blower and upstream of the blower are provided.
  • An embodiment of the invention is in the drawing based on a supply and control device for one Premix burner shown.
  • the device shown has a blower 10, the Speed is controlled depending on the heat demand.
  • the blower 10 conveys into a combustion air duct 12, in which a Aperture 14 is installed as a flow resistance, the effective cross section as described below is adjustable. Downstream of the aperture 14 opens a gas line 16 into the combustion air duct 12, the is controlled by an electric gas control valve 18. Upstream of the aperture 14 is a device 20 for detection the temperature of the combustion air flow provided that for devices with lambda control for converting the Volume flow to mass flow can serve.
  • the controller 32 controls Control component 36 on the gas control valve 18, which the Gas supply in accordance with the control signal y or respectively set size of the effective glare cross section in the sense an optimal fuel-air ratio in a wide range Modulation range of the gas burner affected.
