    • The invention relates to a flame monitoring system (20) for a combustion space (2) having a first ionisation sensor electrode (8) in said combustion space and a second electrode (3). The system comprises an AM signal generator (21) arranged to communicate an AM signal, comprising an amplitude modulation frequency ( f m ), to said first electrode to generate a detection signal. The system further has means (27,28,29,30,31,32) for monitoring a component of said detection signal, corresponding to said modulation frequency and indicative of a presence of a flame in said combustion space. Accordingly, a flame monitoring system is provided which is more robust against dirt and moisture within the combustion space (2).
    • 本发明涉及一种用于在所述燃烧空间中具有第一电离传感器电极(8)和第二电极(3)的燃烧空间(2)的火焰监测系统(20)。 该系统包括AM信号发生器(21),其被布置为将包括振幅调制频率(f m)的AM信号传送到所述第一电极以产生检测信号。 该系统还具有用于监测对应于所述调制频率的所述检测信号的分量并且指示在所述燃烧空间中存在火焰的装置(27,28,29,30,31,32)。 因此,提供了一种对燃烧空间(2)内的污垢和湿气更加坚固的火焰监测系统。

    • The invention relates to an ionisation sensor electrode (9) arranged for detecting the presence of a flame (7) in a combustion space (2) of a combustion apparatus (1). The sensor electrode (9), in operation of said combustion apparatus, is arranged within said combustion space away from said flame. The invention also relates to a combustion apparatus comprising such an ionisation detection sensor. This arrangement reduces the oxidizing rate of the sensor electrode and improves the service life of the sensor electrode and reduces maintenance. Also, less advanced and thus cheaper materials can be applied for the sensor electrode.
    • 本发明涉及一种用于检测在燃烧装置(1)的燃烧空间(2)中存在火焰(7)的电离传感器电极(9)。 在所述燃烧装置的操作中的传感器电极(9)布置在远离所述火焰的所述燃烧空间内。 本发明还涉及一种包括这种电离检测传感器的燃烧装置。 这种布置降低了传感器电极的氧化速率,并且改善了传感器电极的使用寿命并减少了维护。 而且,传感器电极可以应用不太先进且便宜的材料。
