Abstract: A gasification system that includes a gasification reactor chamber having perforated conduits or an inner lining that increases the exposed surface area of waste materials to gasification conditions, thereby decreasing gasification temperature, time, and cooling period between subsequent gasification procedures. After an aspirator withdraws and oxidizes fuel gas from the reactor chamber, a flare assembly combusts the mixed fuel gas to provide power or heat to at least one heat recovery device. The at least one heat recovery device recaptures thermal energy entrained in the exhaust, thereby reducing exhaust temperature and eliminating the need for an exhaust stack. An absorber purifies the exhaust and an extractor removes carbon dioxide. A portion of the removed carbon dioxide may be used for industrial purposes or for supporting vegetation. At least a portion of the remaining exhaust is returned to the reactor chamber as recycled process gas, thereby completing a closed-loop system.

A second burner stage having a second traveling conveyor firebelt with air introduced in a progressively decreasing amount along the length of said second traveling conveyor firebelt and a controller for controlling air introduced to the system. The chamber has a sloped common roof section common to the burner stages and is made of radiative energy reflective fire brick and angled to reflect radiative energy generated from fuel traveling on the traveling conveyor firebelts and directing the radiative energy on fuel traveling on the first firebelt. The air introduced is controlled in amounts so as to automatically minimize excess air to the firebelt conveyors to minimize the quantity of carbon monoxide and nitrogen oxides and other pollutants.

Abstract: A process and method is provided for operating a small-scale high-throughput gasifier. As is known in the art, the exothermic combustion reactions can be separated from the endothermic gasification reactions. The exothermic combustion reactions can take place in or near the combustor while the endothermic gasification reactions take place in the gasifier. Heat from the exothermic zone is transferred to the endothermic reaction zone by circulation of an inert particulate solid such as sand. In order to increase efficiency by reducing heat loss from the gasifier, the gasifier is concentrically-disposed within the endothermic reaction zone of the combustor.
