A controlled zone gasification reactor for a plasma assisted gasification reaction system is disclosed for converting fuel, such as, but not limited to, biomass, to syngas to replace petroleum based fuels used in power generation. The system may be a modular system housed within a frame facilitating relatively easy transportation. The system may include a reactor vessel with distinct reaction zones that facilitate greater control and a more efficient system. The system may include a syngas heater channeling syngas collected downstream of the carbon layer support and to the pyrolysis reaction zone. The system may also include a syngas separation chamber configured to produce clean syngas, thereby requiring less filtering. The system may further include an agitator drive assembly that prevents formation of burn channels with in the fuel.
