Definitions

  • the invention relates to a method for operating a gas burner appliance. Further on, the invention relates to a controller for operating a gas burner appliance and to a gas burner appliance.
  • EP 2 667 097 A1 discloses a method for operating a gas burner appliance.
  • a gas/air mixture having a defined mixing ratio of gas and air is provided to a combustion chamber for combusting the gas/air mixture.
  • the mixing ratio of gas and air of the gas/air mixture corresponds to the so-called ⁇ -value of the gas/air mixture.
  • the gas/air mixture is provided by a mixing device mixing an air flow provided by an air duct with a gas flow provided by a gas duct.
  • the mixing device may be provided by a Venturi nozzle.
  • EP 2 655 971 B1 discloses a method for operating a gas burner appliance, namely for stabilizing the operation behavior of the gas burner appliance for making allowance of disturbances in the air path, the exhaust gas path and the like.
  • the method makes use of a flame ionization signal to increase a lower permissible fan speed that is assigned to a lower modulation limit to compensate disturbances in the air path, the exhaust gas path and the like.
  • EP 2 466 202 B1 and U.S. Pat. No. 5,520,533 A disclose other prior art.
  • the air flow resistance of the gas burner appliance is determined from the pressure difference or from the air mass flow on basis of a characteristic map or characteristic curve. This allows an easy and accurate determination of the air flow resistance of the gas burner appliance.
  • the controller for operating a gas burner appliance according to the present invention is defined in claim 15 .
  • the gas burner appliance according to the present invention is defined in claim 16 .
  • FIG. 2 shows a second gas burner appliance to be controlled by the method and controller of the present invention
  • FIG. 1 shows a schematic view of a first exemplary gas burner appliance 10 .
  • the gas burner appliance 10 comprises a combustion chamber 11 in which combustion of a gas/air mixture M having a defined mixing ratio of gas G and air A takes place during burner-on phases of the gas burner appliance 10 , namely after starting the gas burner appliance and igniting the gas/air mixture M.
  • the combustion of the gas/air mixture results into flames 12 and into exhaust gas E.
  • the flames 12 are monitored by a combustion quality sensor, preferably by a flame ionization sensor 13 providing as output signal an electrical flame ionization current.
  • the flame ionization sensor 13 provides its output signal to a controller 26 .
  • the exhaust gas E emanates from the combustion chamber 11 through an exhaust pipe 29 .
  • the quantity of the air flow A and thereby the quantity of the gas/air mixture flow M is adjusted by the fan 14 , namely by the speed of the fan 14 .
  • the fan speed can be adjusted on basis of a nominal burner-load. A nominal fan speed of the fan 14 depends on the nominal burner load.
  • FIGS. 2 and 3 show schematic views of other exemplary gas burner appliances 10 ′ and 10 ′′.
  • identical reference numbers are used for identical parts.
  • the gas burner appliances 10 , 10 ′ and 10 , 10 ′′ will be described.
  • the controller 26 may generate the control variable for the electric gas flow modulator 18 on basis of the control deviation between the actual value and the nominal value, wherein the gas flow modulator 18 may be operated on basis of this control variable to keep over the entire modulation range of the gas burner appliance 10 the defined mixing ratio of gas and air and thereby the ⁇ -value constant.
  • the pressure difference between the gas pressure and the reference pressure is determined pneumatically a by pneumatic sensor of the pneumatic controller 28 a .
  • the mixing ratio of the defined gas/air mixture is controlled by the pneumatic controller 28 a in such a way that over the entire modulation range of the gas burner appliance 10 the defined mixing ratio of the gas/air mixture M and thereby the ⁇ -value constant is kept constant.
  • the absolute pressure sensor 21 is positioned between the pneumatic gas flow regulator 28 and the mixing device 25 . If the gas regulation valve 28 b of the pneumatic gas flow regulator 28 is in the closed position not gas tight, the absolute pressure sensor 21 may alternatively be positioned between the gas safety valve unit 19 and the pneumatic gas flow regulator 28 .
  • the air flow resistance is compared with a respective first threshold and a respective second threshold. If the air flow resistance is below the respective first threshold, a regular air flow resistance of the gas burner appliance 10 , 10 ′, 10 ′′ is determined and the fan 14 is operated during active combustion at a regular nominal fan speed depending from the nominal burner load or heat demand. If the air flow resistance is above the respective first threshold and below the respective second threshold, a permissible increased air flow resistance of the gas burner appliance 10 , 10 ′, 10 ′′ is detected and the fan 14 is operated during active combustion at an increased nominal fan speed being larger than the regular nominal fan speed.
