GAS SAMPLING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a gas sampling device which can be cleaned easily and in which a heating means can be eliminated from a filter. SOLUTION: This gas sampling device is provided with a probe 10 which takes out a dust-containing gas from the inside of a partition wall A51 through a suction flow passage 10r to which the sucking force of a gas sampling pump (sucking means) 43 is introduced, and a filter 11c which is provided in the probe 10 and removes dust from the dust-containing gas while the gas flows to the downstream side. The probe 10 is provided with a cooling section 10s which cylindrically surrounds the flow passage 10r on the upstream side of the filter 11c.
