Abstract
A diffuser system for multi-outlet pipe structures of the type found in coal pulverizer classifier skirts and in the piping between such classifiers and combustion chambers in coal-fired power plant delivery systems. A plurality of vertical and horizontal diffuser elements comprising toothed bars and rings are arranged in the “skirt” or plenum just prior to the multiple pipe outlets so as to effectively diffuse both axial and radial components of uneven flow distributions.

A non-rotating distribution structure for airborne particulates comprising:
- a continuous cylindrical annular chamber having an inlet for receiving airborne particulates and a plurality of outlets for distributing the airborne particulates to a combustion site;
- said chamber being defined by generally cylindrical and concentric fixed inner and outer interior walls to have an upper and a lower end, the lower end being open to define the inlet, the upper end being contiguously connected to a plurality of outlets arranged around the annular chamber to receive upwardly flowing airborne particulates therefrom, and
- a plurality of diffuser bars arranged in parallel spaced relationship along the inner and outer interior wails between the lower and upper ends of the chamber, each diffuser bar having spaced portions of varying radial dimension extending into the annular chamber.
A non-rotating, multi-outlet distribution structure for airborne coal particulates on their way to a combustion chamber, comprising a continuous cylindrical flow chamber having an upper end and a lower end, an outlet wall terminating the upper end of the chamber, a plurality of distribution outlets formed in the outlet wall, the distribution outlets being symmetrically arranged around an axis coaxial with the flow chamber, a plurality of vertical diffuser bars arranged in parallel spaced vertical relationship along a wall of the flow chamber between the upper and lower ends of the chamber, each vertical diffuser bar having spaced portions of varying radial dimension extending into the flow chamber, and a horizontal diffuser bar disposed in the flow chamber between the vertical diffuser bars, the horizontal diffuser bar having spaced portions of varying radial dimension, the horizontal diffuser bar occupying a generally horizontal, continuous portion of a planar segment of the flow path through the chamber around which at least a portion of the particulate flow may pass unimpeded.
