Definitions

the invention relates to a method and a device for igniting a gas-air mixture supplied to a gas-blown burner, in particular gas surface burner, wherein after pre-ventilation without gas supply and subsequent reduction to normal operating air pressure by the operating air pressure applied to a control valve, the gas supply to the air flow causes the gas-air mixture to Blown gas burner is fed and ignited on this.
Devices for this consist of a blower-equipped air supply line leading to the gas blower burner, to which the gas supply line provided with a full-load throttle and this upstream control valve is connected, the air side of the control valve being connected to the air supply line via an air line.
a walkable but comparatively complex route in this regard would be the possibility of providing a special control valve that can assume different opening positions and this is time-controlled for the starting phase.
control valves for safety reasons as Solenoid valve are formed, wherein the solenoid valve interrupts the further gas supply immediately in the event of a fault.
the invention is based on the object of providing a trouble-free ignition process in a simple manner without having to change anything in the basic structure of the device and in particular in the control valves used hitherto.
the device for carrying out the method consists of an air supply line 3 leading to the gas blower burner 1 and equipped with a blower 8, to which the gas supply line 5 provided with a full-load throttle 4 and this upstream control valve 2 is connected, wherein the air side LS of the control valve 2 is connected to the air supply line 3 via a control pressure line 6.
the gas device G for example designed as a heating boiler, sits above the gas blower burner 1.
the air supply line 3 and the gas supply line 5 are connected to one another, ie this area 10 is designed as a gas / air mixer, from which the gas / air mixture Gas surface burner flows in.
the control valve 2 is a solenoid valve with an air side LS separated by a membrane 2 '. If there is pressure on the membrane 2 ', the valve assumes the open position and a corresponding amount of gas flows to the area 10.
FIG. 3 This entire process is illustrated in FIG. 3, from which it can be seen that the ignition process takes place in a short time span of only about 8-10 seconds.
the decisive factor is the dash-dotted gas pressure curve, which rises steeply to the pre-ventilation pressure when the solenoid valves 11, 11 'open after the pre-ventilation has ended and then drops to the normal operating pressure with a time delay of a few seconds.
the diaphragm 7 is advantageously designed to be adjustable with respect to its opening 7 '. Such influence can, however, and possibly also be achieved in that an air line extension 9 is arranged between the control valve 2 and the orifice 7.
Such an extension can, however, also be an extended or enlarged-diameter control pressure line piece 6 'between the orifice 7 and the control valve 2, it also being possible with a container-like design, as shown in FIG. 2, to adjust the volume of the extension with suitable means to design.
