  • the gas-air ratio must be set independently of the load condition. Especially at burners, not only at rated load, but operate at partial load, this requires one Adjustment of the gas supply according to the air supply.

By selecting the measuring point, the at the Output of the ratio controller as a function of the gas velocity Pending gas pressure a given gas-air Ratio be regulated accordingly. It is about it out possible, this gas-air ratio over different Load cases from extreme low load to full load to maintain. There are no external pressure taps required.
  • the formation of the correct pressure ratio at the gas nozzle depends on the pressure difference at the air supply (Air nozzle) made. Sit the air nozzle and the gas nozzle for example, at the suction connection of a blower, decreases with increasing fan speed and thus with increasing Air flow both the air pressure, and the gas pressure evenly in front of the gas nozzle.
  • the readjustment of the ratio controller is thus based on the gas pressure in front of the gas nozzle performed. This is done pneumatically by a special Throttle arrangement.
  • the pressure regulator is adjusted so that he regulates about the static pressure (atmospheric pressure) at the gas nozzle. An opening of the regulator then takes place in air and Gas take-off pneumatically by the applied pressures.

  • the latter opens the possibility to assume the gas quantity regulation of a control device.
  • the control device may for example be connected to corresponding sensors which detect the calorific value of the gas or the CO content, the O 2 content or the NO x content of the exhaust gas.
  • a correction of the gas-air ratio can then take place on the basis of these measured values, the correction once again being valid for a wide power range.
