Abstract
Abstract This invention features a manifold that divides a stream of coal particles and liquid into several smaller streams maintaining equal or nearly equal mass compositions. The manifold consists of a horizontal, variable area header having sharp-edged, right-angled take-offs which are oriented on the bottom of the header.

Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
140 words
A manifold for uniformly distributing a coal-liquid slurry including coal particles of different size ranges mixed and suspended in said liquid, comprising, in combination, main conduit means conveying said coal-liquid slurry and including sections of progressively decreasing diameter, each said section being joined to its adjacent section by a converging truncated conical member means, and a plurality of downwardly oriented distributor conduits attached to the sections of said main conduit means immediately adjacent and upstream of each of said conical member means, said distributor conduits intersecting said main conduit means and terminating in sharp edge terminal portions with said main conduit means to thereby create turbulence and a pressure drop in the main conduit means adjacent the end of each said distributor conduits whereby improved and substantially uniform coal particle size distribution will result in each of said distributor conduits.
Claim 2
Dependent Claim
140 words
A manifold for uniformly distributing a coal-liquid slurry including coal particles of different size ranges mixed and suspended in said liquid, comprising, in combination, main conduit means conveying said coal-liquid slurry and including sections of progressively decreasing diameter, each said section being joined to its adjacent section by a converging truncated conical member means, and a plurality of downwardly oriented distributor conduits attached to the sections of said main conduit means immediately adjacent and upstream of each of said conical member means, said distributor conduits intersecting said main conduit means and terminating in sharp edge terminal portions with said main conduit means to thereby create turbulence and a pressure drop in the main conduit means adjacent the end of each said distributor conduits whereby improved and substantially uniform coal particle size distribution will result in each of said distributor conduits.
Claim 3
Dependent Claim
36 words
The combination of claim 1 wherein each of said main conduit means sections and said distributor conduits are sized relative to one another to provide substantially equal flow velocity in each of said sections and conduits.
