Bonnie Courtemanche - Holden MA, US
Vlad Zarnescu - Worcester MA, US
Craig A. Penterson - Sutton MA, US

Assignee:

Babcock Power Services Inc. - Worcester MA

International Classification:

US Classification:

110263, 110232, 110347

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.

Abstract:

A flow splitter distributes solid particles flowing in a fluid, such as coal particles flowing in air, through a piping system. The flow splitter includes a divider housing having an inlet configured to connect to an upstream pipe and having an outlet configured to connect to a plurality of downstream pipes, e.g., by way of a divider head. A divider body is mounted within the divider housing. A plurality of divider vanes is included, each extending from the divider body to the divider housing. The divider housing, divider body, and divider vanes are configured and adapted to reduce non-uniformity in particle concentration from the inlet and to supply a substantially equal particle flow from the outlet to each of the downstream pipes.
