The advancing direction of the high-temperature flue gas in the flue faces the opening on the sampling nozzle 11, so that the high-temperature flue gas can conveniently enter the sampling gun 1. Sampling nozzle 11 is made of a high temperature resistant and corrosion resistant material, such as metal, ceramic, and sampling nozzle 11 is illustratively made of a stainless steel material.
