Definitions
- the invention relates to an ignition and flame monitoring device according to the preamble of claim 1.
- a device known from DE-A 37 24 084 switches of this type the flame sensor emits the ignition electrodes when the pilot flame is generated Transformer while the pilot flame continues to burn and from a thermocouple is monitored. So the flame of the pilot burner is constantly monitored and at whose extinction shut the plant down. This means that the pilot flame is constantly on.
- ignition and flame monitoring devices are known, in which the same the main burner flame is ignited with the help of a spark igniter so that the Pilot burner and the gas consumption it causes are eliminated.
- the main burner MB of a burner system is via a first main burner valve MV1 and a second valve MV2 supplied with gas. Between the two valves MV1 and MV2 branches off a line to the pilot burner valve PV, which is the pilot burner PB feeds. This is assigned an ignition electrode ZE, which is generated by an ignition generator IG is supplied with ignition pulses.
- the timer ZG serving as a safety timer carries over its output signal the line L3 to the safety switch SI, whose contact si in the power supply line between an AC voltage source V, e.g. the AC mains voltage, and one Heat demand switch WB is located.
- the three gas valves MV1, MV2 and PV are Solenoid valves and each equipped with an excitation winding E1, E2 or E3.
- the Safety switch SI opens its contact si as soon as it is triggered by the timer ZG Line L3 a blocking signal is supplied. The contact si can only be done manually getting closed.
- the main burner valve MV1 can be a servo-controlled Act control valve, which depends on the gas flow rate to the main burner MB regulates the amount of heat demand.
- the second valve MV2 is a conventional one Closing valve. Both valves MV1 and MV2 and possibly also the pilot burner valve PV can be accommodated in a common housing in a known manner.
- the flame amplifier FV does not generate one Output signal so that the timer ZG after its delay time over the Line L3 triggers the safety switch SI and its contact si the entire system switches off. Since the power supply to all three valves is interrupted will, these valves go into the closed position so that gas neither to the pilot burner nor to the Main burner flows.
- This arrangement is particularly advantageous because the main burner MB with a lean gas / air mixture can be operated, which generates low pollutants, but is difficult to ignite. It is therefore not directly affected by electrical sparks, but ignited by the flame of the pilot burner PB, which in turn has a rich one Gas / air mixture operated and can be easily ignited. Because the pilot burner is switched off during normal operation, it does not generate any during normal operation Pollutants.
