Abstract
This invention incinerates bio-active, or any solid wastes with high organic contents and a major recoverable liquid component, at an extremely high temperature with minimum added fuel, air pollution, space, time and labor. This invention removes the liquid components through a separate route from the combustion zone, maintains a very high incineration temperature for a complete oxidation of dried solid by minimizing the exhaust gas volume, excess combustion air, the exit exhaust gas temperature and the heat loss with a use of a matched pair of high-temperature ceramic heat recuperators which have very large surface area per mass.
Claims9
An incinerator for bio-active solid wastes comprising:
- a. a high temperature combustion zone wherein dry solid components of said wastes are oxidized;
- b. a pair of substantially identical heat recuperators, one for preheating an air stream to a preset high temperature before entering said combustion zone and the other for removing a substantial portion of the sensible heat from the exhaust gas stream leaving said combustion zone, alternately;
- c. means for controlling flow and direction of said air stream and said exhaust gas stream under a slight vacuum;
- d. means for adjustably supplying said solid wastes to said combustion zone;
- e. means for progressively removing the volatile component from said solid wastes away from said combustion zone and said exhaust stream;
- f. means for heating said combustion zone and said recuperators for start-up;
- g. means for removing ashes from said exhaust gas stream and said combustion zone;
- and
- h. means for monitoring said preset temperature and the Oxygen level in said exhaust gas stream.
