NOVELTY - Conversion of a solid, carbonaceous material to a low tar fuel gas within a gasification reactor chamber (50) comprises transforming a first portion of a carbonaceous material into a char material at a flaming pyrolysis zone, controlling temperatures by injecting oxidizing gas, varying a location of the flaming pyrolysis zone by increasing or decreasing an amount of oxidizing gas injected, controlling a porosity of the char material and a second portion of the carbonaceous material, and converting the char material and the second portion of the carbonaceous material to the low tar fuel gas.    USE - The method is used for the conversion of a solid, carbonaceous material, e.g. woody biomass, non-woody biomass, cellulosic product, cardboard, fiber board, paper, plastic, or food stuff to a low tar fuel gas (claimed).    ADVANTAGE - The invention accurately controls variables of gasification, provides effective gas cooling, operates without the use of scrubbing liquid, and accommodates computer control of a networked group of modular biopower systems.    DETAILED DESCRIPTION - Conversion of a solid, carbonaceous material to a low tar fuel gas within a gasification reactor chamber comprises:    (A) transforming a first portion of a carbonaceous material into a char material at a flaming pyrolysis zone;    (B) controlling temperatures along a length of the chamber by injecting oxidizing gas;    (C) controlling an amount of the oxidizing gas injected;    (D) varying a location of the flaming pyrolysis zone by increasing or decreasing an amount of oxidizing gas injected upstream or downstream of the zone;    (E) controlling a porosity of the char material and a second portion of the carbonaceous material by applying a force; and    (F) converting the char material and the second portion of the carbonaceous material to the low tar fuel gas.    INDEPENDENT CLAIMS are also included for:    (1) an automated method for removing a tar from a fuel gas generating device;    (2) an automated gasification reactor apparatus for converting a solid, carbonaceous material to a fuel gas, comprising a heat source, injection tubes penetrating a gasification reactor wall (101), and a moveable grate located at a downstream outlet of a gasification reactor chamber, where the injection tubes comprise nozzles configured to deliver the oxidizing gas in a direction generally non-perpendicular to a direction of flow of the fuel gas;    (3) an integrated, automated power system, comprising a process automation controller in operative association with a fuel gasification reactor, a gas cooler, a gas filter, a fossil-fueled energy conversion device, and a process automation controller; and    (4) an automated, modular, distributed architecture, comprising a central client server and an integrated, automatic power system.
