Definitions

  • the invention relates to a method and an apparatus for Ignition of a gas fan burner, in particular gas surface burner supplied gas-air mixture, after pre-ventilation without gas supply and subsequent reduction to normal operating air pressure due to the operating air pressure at a control valve the gas supply to the air flow causes the gas-air mixture fed to the gas fan burner and ignited at this becomes.
  • Devices for this consist of a gas fan burner leading, blower-equipped air supply line to which those with a Full throttle and this upstream control valve Gas supply line is connected at the mouth, the air side the control valve via an air line with the air supply line in Connection is established. See DE-A-31 05 862 A1. It became particular for gas surface burners and their operation with liquid gas or when operating them with a large air ratio, e.g. setting for natural gas group E or L, observed that it was temporary when igniting such burners because of a mixture that is too lean no flame formation occurs.
  • a walkable but comparatively complex Way would be to provide a special control valve, that different opening positions can take and this is time-controlled for the start phase. To make matters worse added that such control valves for safety reasons as Solenoid valve are formed, the solenoid valve in the event of a fault the further gas supply is interrupted immediately.
  • the invention is based on the method and the device of the type mentioned the task in simple Way, without sacrificing the basic structure of the device and especially in the control valves previously used for this need to change for a trouble-free ignition process to care.
  • the solution is based on the indicator of claim 1 and with respect to the device according to the characteristics of claim 2.
  • the inventive method and the device are as follows based on the graphic representation of exemplary embodiments explained in more detail.
  • Fig. 1 there is the device for performing of the method from a gas blower burner 1 leading with a blower 8 equipped air supply line 3 to which the with a full-load throttle 4 and this upstream control valve 2 provided gas supply line 5 is connected, where the air side LS of the control valve 2 via a control pressure line 6 is connected to the air supply line 3.
  • Gas-blown burner 1 sits, for example, designed as a boiler Gas device G.
  • area 10 are the air supply line 3 and the gas supply line 5 connected to each other, i.e. this area is 10 designed as a gas / air mixer, from which the gas / air mixture flows to the gas surface burner.
  • Control valve 2 is a solenoid valve with through a membrane 2 'divided air side LS. Is on the membrane 2 'pressure on, the valve assumes open position, and the area 10 flows a corresponding amount of gas.
  • control valve 2 resets accordingly far, and it can only flow through a corresponding amount of gas, which together with the appropriate amount of air for normal burner operation corresponding gas / air mixture results, but that to the can lead to the aforementioned ignition difficulties.
  • connection or control pressure line 6 an aperture 7 or throttle arranged, which is crucial causes that on the air side LS of the control valve 2 not immediately a corresponding pressure drop occurs because that is there existing pressure air cushion thanks to the throttle or cover 7 can not degrade so quickly in the direction of air supply line 3.
  • the Aperture 7 is advantageously adjustable with respect to its opening 7 '. Such influence can also and if necessary additionally can be achieved in that between the control valve 2nd and the cover 7 an air line extension 9 is arranged.
  • Extension can also be an extended one or diameter enlarged control pressure line piece 6 'between Act aperture 7 and control valve 2, it being container-like Training, as shown in Fig. 2, is also possible with suitable Means to make the volume of the extension adjustable.

  1. Procédé d'ignition d'un mélange de gaz et d'air amené à un brûleur à soufflante à gaz (1), en particulier à un brûleur de surface à gaz, cependant qu'après ventilation préliminaire sans arrivée de gaz et avec réduction suivante à une pression de service normale grâce à la pression de service existante sur une soupape de réglage (2), l'arrivée de gaz vers l'écoulement d'air provoque que le mélange de gaz et d'air est amené au brûleur à soufflante à gaz (1) et est allumé sur celui-ci,
    caractérisé en ce
    que la pression d'air constituée sur la vanne de réglage (2) pendant la phase de ventilation préliminaire est diminuée de manière retardée à la pression d'air de service normale du brûleur à soufflante à gaz (1) et que pendant cette phase de diminution une quantité de gaz plus importante que la quantité de gaz affluant en marche normale est amenée à l'air.
  2. Dispositif pour exécuter le procédé selon la revendication 1, constitué par une conduite d'arrivée d'air (3) menant au brûleur à soufflante à gaz (1), équipée d'une soufflante, à laquelle une conduite d'arrivée de gaz (5) est raccordée en y débouchant, qui présente une soupape d'étranglement de pleine charge (4) et une soupape de réglage (2) placée en amont de celle-ci avec un côté air (LS) et un côté gaz, le côté air (LS) qui est sinon étanche à l'air de la soupape de réglage (2) étant relié à la conduite d'arrivée d'air (3) par une conduite de pression de commande (6),
    caractérisé en ce
    qu'un obturateur (7) est placé dans la conduite de pression de commande (6).
  3. Dispositif selon la revendication 2,
    caractérisé en ce
    que l'obturateur (7) est configuré de grandeur variable pour ce qui est de son ouverture (7').
  4. Dispositif selon la revendication 2 ou 3,
    caractérisé en ce
    qu'un élargissement de conduite d'air (9) de volume réglable est placé entre la soupape de réglage (2) et l'obturateur (7).
