The utility model relates to hydrogen chloride synthesizing equipment in a polycrystalline silicon manufacturing technology, in particular to a flame detection device for a hydrogen chloride synthesizing furnace. The flame detection device comprises a flame detection port I and a flame detection port II, wherein the tubular flame detection ports (I and II) are arranged on the furnace body of the hydrogen chloride synthesizing furnace, serve as field observation ports, and are arranged horizontally; and a 180 DEG included angle is formed between the flame detection ports. The flame detection device is characterized in that a flame detection port III and a flame detection port IV which are in the same height with the flame detection port I and the flame detection port II are also arranged on the furnace body; the flame detection ports (III and IV) are also tubular and are arranged upwards in an inclined manner; and the openings of the tubular flame detection ports (III and IV) face upwards, so that flame can be
