Document Type and Number:
Japanese Patent JP7420662
Kind Code:
B2
Abstract:
Provided is a combustion device, comprising: a plurality of burners (2) arranged side by side at the lower part in the combustion casing (1), a branch pipe (3) for supplying fuel gas to the burners (2), a heat exchanger (4) heated by combustion gas from the burners (2), and a fan for sucking the combustion gas passing through the heat exchanger (4). The branch pipe (3) is composed of a branch pipe body (3a) and a cover (3b). The branch pipe body is provided with a plurality of protruding nozzles for ejecting a fuel gas toward the inflow port (22) of the mixing pipe portion (21) of each burner (2). The cover (3b) partitions the distribution chamber (32) of the fuel gas between the branch pipe body (3a) and the cover (3b), so as to reduce the cost of the branch pipe (3). The solution is that the branch pipe body (3a) is formed by stamping of a plate material. Furthermore, the protruding height of the nozzle (31) is set to a height that can be press formed by one stamping process.
