Claims

[Scope of utility model registration request]

The powder introduced into the vertical duct exchanges heat with the gas flowing from bottom to top while swirling inside the vertical duct, and the powder is introduced into the duct from the powder inlet. A powder dispersion device in a vertical duct, characterized in that a powder dispersion plate is installed that blocks the swirl so that the powder is not affected by the swirl and extends downward from the part where the powder input port is located. .
