The utility model discloses a smoke sampling device. The smoke sampling device comprises a sampling pipe (11), as well as a filtering part (10) and an equipment connecting part (12) which are respectively connected with two ends of the sampling pipe, wherein the sampling pipe (11) consists of an outer pipe (3) and a corundum lining (4) which is arranged in the outer pipe (3). According to the smoke sampling device, large smoke particles in a boiler can be filtered through the filtering parts, the problem that the soot concentration in the smoke is high and blocks the smoke sampling device can be solved, furthermore, the sampling pipe comprises the corundum lining, the corundum has stable performance, so that smoke in the sampling pipe reacts with the sampling pipe to further influence the analysis result and shorten the service life of the sampling pipe.
