Abstract

An elbow for a solid particle conveyance system includes an elbow body having an inlet duct and an outlet duct with an interior space defined between the inlet and outlet ducts. An aeration insert is mounted to the elbow body for aerating solid particles passing through the interior space of the elbow body. The aeration insert is mounted to the elbow body to provide aeration from an elevation between that of the inlet duct and the outlet duct to facilitate downward movement of solid particles from the inlet duct across the aeration insert, and out through the outlet duct.

Claims

1. An aeration insert for an elbow in a solid particle conveyance system, comprising:

a base flange configured and adapted to be mounted to a lower access port of an elbow body; and

a riser extending from the base flange configured and adapted to extend into the interior space of an elbow body; and

an aeration membrane mounted to the riser opposite the base flange, wherein the aeration membrane is defined in a plane parallel to the base flange.

2. An aeration insert as recited in claim 1, wherein the riser extending from the base flange is configured and adapted to place the aeration membrane at a height between that of an inlet duct and an outlet duct of an elbow in a solid particle conveyance system to facilitate downward movement of solid particles from the inlet duct across the aeration insert, and out through the outlet duct.
