PURPOSE: A dual air exhaust pipe of a boiler for blocking the inflow of water is provided to prevent the performance degradation and malfunction of a boiler in advance due to the inflow of water and to significantly improve the drainage performance of an air pipe. CONSTITUTION: A dual exhaust gas pipe of a boiler for blocking the inflow of water comprises an air exhaust pipe(30) and an air intake pipe(40). The air exhaust pipe discharges the exhaust of a boiler through a connection(32) into the air exhaust discharge hole(34) of a body. The air intake pipe comprises a plurality of rectangular air intake supply holes(44); is installed on the outer surface at a regular interval; supplies air which is supplied from the outside into the boiler through an air intake adapter(42) in response to suction force. A water guiding passage with a predetermined width along the bottom central line of the air intake pipe is formed by changing the punching position of the air intake supply hole in the air intake pipe. The innermost of the air intake supply hole integrally forms a ring type backflow cutoff projection(48) by the inside. |
