STOVE PIPE CONNECTING STRUCTURE OF INTAKE AND EXHAUST PIPE FOR BOILER

摘要

The present invention relates to the connection structure of stove pipes of intake and exhaust pipes of a boiler which facilitates the connection structure by connecting the stove pipes connected to the boiler and the exhaust pipe with a seamed pipe of a reversed L-shape inserted into the intake pipe. The present invention includes the cylindrical intake pipe (10) sucking air of the outside of a wall (2) via an inlet (11) formed on the outer circumference and supplying the air to the inside of the boiler (1); the seamed pipe of a reversed L-shape inserted into the intake pipe; the exhaust pipe (30) which is connected to a lateral flange (21) of the seamed pipe (20) and discharges combustion gas inside the boiler (1) to the outside; and the lower stove pipe (40) which is connected to the boiler (1) and formed on a connection unit (22) on the lower side of the seamed pipe (22).
