US Patent:

39560767, May 11, 1976

Filed:

Jan 16, 1975

Appl. No.:

5/542027

Inventors:

Orlo A. Powell - Wethersfield CT
Angelo J. Roncari - East Granby CT

Assignee:

Urban Research & Development Corporation - East Granby CT

International Classification:

B22D 2308

US Classification:

264 14

Abstract:

Solid waste material is disposed of and a portion thereof converted into valuable refractory material within a reactor having a substantially vertical pyrolysis chamber, a refuse charging inlet and a combustible gas outlet in the upper region thereof and a molten refractory material outlet in the lower region thereof. Gas-feed means charges an oxygen-rich gas into the chamber under pressure at a plurality of vertically spaced points along the length thereof so as to produce combustion of the waste organic components and generate heat. The charge is controlled to maintain a plurality of different temperature zones along the length of the chamber so as to effect incomplete combustion of the waste organic component and form a combustible gas and an organic-free molten refractory material. Preferably the gas-feed means includes a substantially vertical core member with the chamber, for receiving and channeling the oxygen-rich gas through conduits therein, and the distribution of the oxygen-rich gas among the various conduits is controlled by temperature sensors located within the various temperature zones. The molten refractory material is prilled to form ceramic prills which are recovered as a product of the process.

Abstract:

Solid waste material is disposed of and a portion thereof converted into valuable refractory prills by use of a reactor having a substantially vertical pyrolysis chamber, a refuse charging inlet and a combustible gas outlet in the upper region thereof and a molten refractory material outlet in the lower region thereof. The molten refractory material withdrawn from the chamber is prilled to form ceramic beads. Gas-feed means charges an oxygen-rich gas into the chamber under pressure at a plurality of vertically spaced points along the length thereof so as to produce combustion of the waste organic components and generate heat. The charge is controlled to maintain a plurality of different temperature zones along the length of the chamber so as to effect incomplete combustion of the waste organic component and form a combustible gas and an organic-free molten refractory material. Preferably the gas-feed means includes a substantially vertical core member with the chamber, for receiving and channeling the oxygen-rich gas through conduits therein, and the distribution of the oxygen-rich gas among the various conduits is controlled by temperature sensors located within the various temperature zones. The solid waste material may be compacted prior to being charged through the refuse charging inlet.
