Mobile solid waste gasification unit

Abstract

A mobile waste gasification system comprised of a container, at least one gasification chamber, and a produced fuel gas combustion chamber, and may include a control room. Waste material is loaded into a suspended mesh liner that is offset away from the walls of the gasification chamber, thereby increasing the surface area of waste materials that are exposed to gasification conditions, and thus decreasing gasification temperature, time, and cooling period between subsequent gasification procedures. Process gas and supplemental flaring gases are preferably comprised of an oxygen or hydrogen rich gas. Produced fuel gases are withdrawn from the gasification chamber and into the produced fuel gas combustion chamber. The produced fuel gas combustion chamber may be comprised of a maze ignition chamber for the flaring of said fuel gases. Alternatively, the fuel chamber may be comprised of a gas accumulation tank that stores the produced fuel gas.
