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 The molten refractory material withdrawn from the chamber is prilled to form ceramic beads.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. The combustible gas may be processed to recover tars, and it may be burned to generate heat for producing power. The solid waste material contains as minimum weight values about 2.0 per cent of glass and ceramics, 18.0 per cent of paper products, 3.0 per cent of metals and 6.0 per cent of food waste and other organic materials.
