Abstract
An orifice plate for improving particle distribution within a coal piping system includes a plate body defining a central orifice therethrough bounded by an inner periphery of the plate body. The plate body is configured and adapted to be affixed between end flanges of adjacent pipes in a coal piping system so as to generally align the central orifice with an internal flow passage through the coal piping system. Flow disruption features are defined in the inner periphery of the plate body. The flow disruption features are configured and adapted to disrupt a flow of air and particles flowing through the central orifice to provide a more uniform distribution of particles downstream of the plate body than upstream.
