A gasification system for solid wastes having a thermal reactor (20) and a mechanical gas cleaner (70), an indirect heat exchange cooler (120), and an electrostatic precipitator (130) for cleaning and cooling the produced gas. Feed material is continuously fed to the central section of the thermal reactor (20) above an air introduction manifold (38) and nozzles (40) in an upward direction, forming a stratified charge. As feed material moves upward and outward from the reactor center, it is reduced to ash. An agitator (54) assures contact between the hot particulate product and hot gases resulting in gasification of the feed material and net movement to the sidewall of the thermal reactor (20) forming an ash. The air introduction nozzles (40) serve as a grate. Ash descends along the sidewall to the reactor base for removal. |
