Definitions

  • the invention relates to a method and a gas blower burner unit for preventing the formation of condensate drops in the pressure pulse line between the gas supply fitting of a gas blower burner and the combustion chamber of a gas boiler equipped with the gas blower burner.
  • the invention has for its object to provide a method for preventing the formation of condensate droplets and a gas blower burner assembly or to improve that a trouble-free burner operation is guaranteed in the long term in the respective operating period.
  • a purge air supply line is arranged on the further pressure pulse line, the cross section of which is effective for the purge air passage and is dimensioned smaller than the cross section of the pressure pulse line.
  • the purge air supply line is designed as a capillary tube of correspondingly small dimensions.
  • a further advantageous embodiment is that the confluence of the purge air line and the pressure pulse line is arranged in the direction of the open end of the pressure pulse line connected to the combustion chamber.
  • blowers on the gas fan burner per se are also used, i.e.
  • the purge air line is connected with its other end, which can be acted upon with purge air, to the blower housing on its pressure side, whereby it is also possible to carry out a test experiment to select the most favorable location on the blower housing, which ensures that the gas supply via the sensor does not come from the purge air side control pressure to be controlled is seriously falsified.
  • the arrangement of the aforementioned purge air flow regulator is also advantageous in this respect.
  • FIG. 1 which illustrates the arrangement and design principle of a gas blower burner assembly in association with a gas boiler which is only shown schematically, the gas blower burner assembly still consists of a gas supply fitting 1 with a gas line 4 leading into the blower housing 2 of the burner 3 , from a pulse line 5 connecting the blower housing 2 to the gas supply fitting 1 and from a further pressure pulse line 6 for connection to the combustion chamber 7 receiving the burner head 3 '.
  • a purge air supply line 8 is arranged between the further pressure pulse line 6 and whose cross section 8 ′ effective for the purge air passage is dimensioned smaller than the cross section 6 ′ of the pressure pulse line 6.
  • the purge air supply line 8 is equipped with a purge air quantity regulator 9, and furthermore the purge air supply line 8 is connected with its other end 8 ′′ ′′ which can be acted upon with purge air, to the blower housing 2 on its pressure side.
  • the opening 8 ′′ of the purge air supply line 8 into the pressure pulse line 6 is arranged in the direction of the open end 6 ′′ of the pressure pulse line 6 connected to the combustion chamber for the reasons mentioned above.
  • the purge air quantity controller 9 is expediently not, as shown in FIG. 1, in the purge air line itself arranged, but directly on the blower housing 2 and forms the connection for the purge air supply line 8th
  • the pressure pulse line 6 leading to the sensor is under a correspondingly stationary pressure corresponding to the pressure in the combustion chamber 7, i.e. so far there is no flow in the pressure pulse line 6, and only changing pressure communicates via pressure pulse line 6 to the sensor, which then controls the gas line 4 to the mixing chamber 2 'of the burner 3 in a known manner.
  • the pressure pulse line 6 is connected to the blower housing 2 through the purge air supply line 8, when the burner 3 and thus the blower G are switched on, appropriately dimensioned purge air is introduced into the pressure pulse line 6, which can only flow out in the direction of the combustion chamber 7, for example in the pressure pulse line 6 also condensed condensate to drain and thus prevents droplet formation.
  • this is an undisturbed, i.e. Uniform burner operation guaranteed via a correspondingly regulated gas supply to the mixing room 2 'in the burner.
