| 摘要 |
A burner ignition and flame monitoring system is disclosed in which a hot surface ignitor (24) has a duel function. The hot surface ignitor (24) is first used as an ignitor element and then as a flame rod or sensing means of a flame rectification system. If the flame has established the ignitor (24) actuates on a control means (35) via a flame sensing circuit (50). The control means (35) switches a control switch (23) to deenergize the ignitor (24) when the flame has established. |
