NOVELTY - The chamber has a rotatable agitator drive assembly (40) arranged in a reactor vessel extending into a combustion reaction zone and defining a portion of the zone with a burner. The assembly includes a hollow portion formed from a conduit. A syngas separation chamber (36) positioned in the hollow portion separates contaminants from syngas such that syngas with contaminants are passed into the burner. A turbine separates syngas from contaminants such that the contaminants are located near an outer wall and uncontaminated syngas is located closer to an axis of the separation chamber.    USE - Plasma assisted gasification reaction chamber for converting biomass into electricity, in an internal combustion engine e.g. diesel engine and turbine engine in villages and desolate populations.    ADVANTAGE - The rotatable burner rotates within the reactor vessel to reduce formation of burn channels in the fuel held in the reactor vessel in an effective manner. The chamber allows utilizing household rubbish as shredded fuel to create syngas, thus reducing the diesel fuel consumption power generation up to 90 percent and eliminating rubbish with minimal contaminant discharge in the air in an effective manner. The chamber reduces contaminates in the syngas, thus producing syngas that requires less filtering and more readily usable in an engine without requiring extensive filtering. The chamber produces syngas with less contaminates, thus resulting in less contamination buildup in the engine. The syngas heater increases the efficiency of the engine without negatively impacting the reactor vessel in an effective manner. The chamber provides cost efficient power to villages and desolate populations. The chamber facilitates easy transportation and easy shipment over land, sea, rail and air.
