NOVELTY - Water is recovered from waste material, and converted into superheated steam using exhaust heat. Superheated steam is sprayed on waste material, and dry distillation is performed. Distillation residue, carbonaceous gas and superheated steam are fed into reaction chamber (5). Charcoal accompanied with carbonaceous gas, oil component and pulverized distillation residue are heated. Gas is converted into carbon dioxide and water by oxidation, cleaned with alkali, and converted into gas fuel. Electric power is then generated using gas fuel.    USE - For generating electric power using waste material such as foodstuffs residue e.g. foodstuffs sludge, organic waste such as human waste, sewage sludge and livestock excrement, waste plastics, waste paper and saw dust.    ADVANTAGE - Electric power is quickly and economically generated using waste material.    DETAILED DESCRIPTION - Moisture content is recovered from a waste material by carrying out cooling condensation. The recovered water is utilized as superheated steam using exhaust heat of an apparatus. The superheated steam is sprayed on waste material, and dry distillation is carried out. The dry distillation residue, carbonaceous gas and superheated steam are introduced into high-temperature reaction chamber (5). Charcoal accompanied with carbonaceous gas, oil component and pulverized dry distillation residue are further heated. An explosive reaction is inhibited for air accompanied with carbonaceous gas, when gasifying by water gas reaction in inert atmosphere of water vapor. The gas is converted into carbon dioxide and water by oxidation. Then, alkali cleaning of the gas is carried out. The cleaned gas is converted into gas fuel excluding hydrogen chloride and other harmful gas. Electric power is then generated using the gas fuel. Thus, electric power generation is enabled. An INDEPENDENT CLAIM is included for electric power generating apparatus (2).    DESCRIPTION OF DRAWING(S) - The figure shows the systematic diagram of electric power generating apparatus.
