Abstract
An improved method for pyrolyzing waste materials and recovering useful chemical and energy rich materials therefrom. The apparatus of the invention includes a specially designed, rotatable combustion chamber and embodies a highly novel means for withdrawing a portion of the combustion gases generated by the pyrolysis of the waste materials, mixing these gases with preheated air in carefully controlled proportions and then using the highly combustible gaseous mixture thus formed to sustain pyrolysis within the combustion chamber.
Claims3
A method of continuously pyrolyzing waste materials and recovering therefrom useful, energy producing materials and chemical by-products, comprising the steps of:
- (a) continuously introducing the waste materials to be prolyzed into a combustion chamber;
- (b) raising the temperature of the combustion chamber to a temperature sufficient to pyrolyze the waste materials;
- (c) drawing from the combustion chamber a portion of the combustion gases produced by pyrolysis of the waste materials;
- (d) drawing oxygen containing gas from externally of the combustion chamber;
- (e) raising the temperature of the oxygen containing gas to approximately the temperature of the combustion gases;
- (f) controllably mixing the combustion gases and the oxygen containing gas to produce a combustible gaseous mixture;
- and
- (g) burning the gaseous mixture thus formed to heat the combustion chamber.
