Beschreibung
Zusammenfassung:	The invention discloses a boiler flue gas sampling method. Most flue gas samplers are relatively simple in structure and are not provided with cooling structures, the temperature of sampled flue gas is relatively high, and subsequent detection is not facilitated. The method comprises the following steps: high-temperature flue gas is sucked into a sampling pipe main body through a first air suction piston, and then the first air suction piston is pushed out to push the high-temperature flue gas into a cyclone separator to separate dust; meanwhile, a second air exhaust piston exhausts air to ensure the movement speed of the flue gas in the cyclone separator, the second air exhaust piston pushes the flue gas into a cooling pipeline in the water cooling box, and the high-temperature flue gas exchanges heat with cooling water pre-stored in the water cooling box in the circulation process to reduce the temperature of the flue gas; and then the flue gas is connected with detection equipment through the gas outlet fo
