[Problems] Provided is a combustion gas bleeding probe, which is elongated in lifetime and improved in chlorine removing ability and so on. [Means for Solving Problems] The combustion gas bleeding probe (1) comprises a cold gas discharge means having a plurality of discharge ports (2b) for discharging cold gases (C) substantially perpendicularly of the suction direction (S) of a combustion gas (G) and toward the center of the combustion gas flow. A vector (A), which is composed of momentum vectors (MVs) of the cold gas (C) discharged individually from the plural discharge ports, has a vertically downward component. This vertically downward component of the synthesized vector is made the larger, as the angle between the suction direction of the combustion gas and the flow direction of the combustion gas before sucked by the probe becomes the closer to a right angle. The vertically downward component of the synthesized vector is made the smaller, as the suction direction of the combustion gas and the flow direction of the combustion gas before sucked by the probe become the closer to parallel. Two to six discharge ports can be arranged in a plane normal to the sucking direction of the combustion gas by the probe. |
