US Patent:

20070251334, Nov 1, 2007

Filed:

May 1, 2006

Appl. No.:

11/414389

Inventors:

David Akers - Indiana PA, US
Clifford Raleigh - Home PA, US
Glenn Shirey - Delmont PA, US
David Urchek - Blairsville PA, US

International Classification:

G01N 1/20

US Classification:

073863710

Abstract:

A method of and apparatus for collecting samples from a flowing stream in which an elongated sampling device including inner and outer concentric, relatively rotatable tubular members is positioned in and extends across the stream. The tubular members each have a longitudinally extending slot at least as long as the transverse width of the stream, with the slots being wider, and preferably at least about three times wider than the dimension of the largest particles contained in the stream. To take a sample, the inner tubular member is rotated to position its slot facing upstream, then the outer tubular member is rotated to position its slot in alignment with the slot in the inner tubular member to permit material from the stream to flow into the inner tubular simultaneously across the full width of the stream. When samples are not being taken, at least the outer tubular member is rotated to so that its slot faces downstream.

Abstract:

Disclosed is a pelletized fuel composition comprising coal fines in an amount of from 60% to 80% by weight, paper making sludge in an amount of from 10% to 30% by weight, and a shredded polymeric material in an amount of from 0. 5% to 15% by weight. Surprisingly and unexpectantly, a high percentage of correctly sized pellets having a desired degree of hardness and structural integrity result without the necessity of a binder, the use of very high pressures or drying the completed pellets by heating at elevated temperatures. A method of manufacturing the fuel composition involving pelletizing at a pressure of from about 1,000 psig to about 4,000 psig is also disclosed.
