Technical field of flue gas denitrification treatment equipment, involving a type of flue gasFlue Gas PreheaterThe assembly includes a housing, an inlet connection passage that fits over the intake pipe, and an outlet connection passage that fits over the exhaust pipe. The inner wall of the inlet connection passage is flush with the outer wall of the intake pipe, and the inner wall of the outlet connection passage is flush with the outer wall of the exhaust pipe. The inner wall of the inlet connection passage features a circular sealing groove, and the outer wall has apertures that connect to the sealing groove. These apertures are connected to a tube at one end, which in turn is connected to a pump at the opposite end. The outlet connection passage is configured similarly to the inlet connection passage. This novel design effectively and stably seals the pipe connection points, preventing the leakage of original smoke.
Flue gas preheaters, also known as flue preheaters, are a type of preheating equipment designed to enhance the heat exchange performance of boilers and reduce heat loss. The function of a flue gas preheater is to transfer the heat carried by the flue gas exiting the boiler tail pipe to the air before it enters the boiler, preheating the flue gas to a certain temperature.
