US Patent:

49292544, May 29, 1990

Filed:

Jul 13, 1989

Appl. No.:

7/379590

Inventors:

Cornelis A. Kooiman - Rhoon, NL
John J. McDevitt - Bow NH

Assignee:

SET Technology B.V. - Goes

International Classification:

C10J 326
C10J 342

US Classification:

48 76

Abstract:

A gasifier system for obtaining relatively clean combustible gaseous products from solid fuel materials, such as processed sewage sludge, comprises a gasifier reactor which communicates a raw, combustible gas to a cyclone separator, a gas scrubbing device and a gas cooling and drying device. Gas which exits the system is relatively clean and may be used in a prime mover for the production of energy. The gasifier reactor of the present invention is a down-draft fixed bed gasifier. The gasifier is constructed of several interconnected modular units. Moreover, the gasifier is constructed so as to efficiently gasify fuel materials while maintaining excellent horizontal temperature control.
