Claims

[Scope of utility model registration request]

In a gas mixing device in which the end of a rectangular second duct is joined to a rectangular first duct, the first duct is parallel to the wall of the first duct surrounded by the joining line formed by the joining, that is, the joining surface. Between the plurality of partition plates provided in the first duct, the wall of the first duct facing the joint surface, and the joint surface, the partition plate is arranged substantially perpendicular to the joint surface and parallel to the axis of the first duct. A plurality of mixing partition plates are provided, and the longitudinal cross section of the mixing partition plate is included in the central plane of the mixing partition plate, and the axis is along the axis of the second duct from the joint surface to the partition plate furthest from the joint surface. The mixing duct is also provided with a mixing duct having a flat cross section that penetrates through the interior space, and the long axis of the mixing duct is sequentially shortened each time it passes through each partition plate, and the joining surface is on the upstream side and A gas mixing device characterized in that an opening is formed in a predetermined shape between the mixing ducts.
