NOVELTY - The power generation apparatus (40) uses a compactly molded solid fuel consisting of ground coal (2) as a main component and having sodium carbonate (6) and calcium oxide (4).    USE - For generating power using coal.    ADVANTAGE - Since solid fuel consisting of ground coal, calcium oxide and sodium carbonate is used in the gasification reactor, power generation apparatus ensures stable supply of electric power for a long period of time. Electric power and heat energy are produced efficiently, without the need for a large scale installation. Since calcium oxide is recovered from the residue generated in the reactor, for formation of solid fuel, the power generation system enables savings in energy and resources.    DETAILED DESCRIPTION - A fuel cartridge (14) consisting of solid fuel formed by mixing dry sodium carbonate powder and dry calcium oxide powder to ground coal is covered by a hydrogen gas-impermeable film (8). The solid fuel reacts with water at the temperature of 873-1273 k, and 10-25 MPa pressure to form a product gas. The fuel cartridge is accommodated in a high temperature, high pressure gasification reactor. The product gas consisting of hydrogen as the main component is formed in the reactor and is used as substitution gas for the reactor. A solid substance consisting of calcium carbonate is formed as a residue in the reactor. An INDEPENDENT CLAIM is included for power generation system which has a raw material recovery installation (50) in which calcium carbonate formed in the reactor is heated to form calcium oxide and carbon dioxide. Calcium oxide is recovered and transported to a fuel manufacturing equipment for production of the solid fuel. A single raw material recovery installation recovers calcium oxide and carbon dioxide from several power generators. Electric power and low temperature heat energy produced in the power generation apparatus is used as a source of power distribution. Carbon dioxide recovered from calcium carbonate is pressurized by a pressurization device and stored at the bottom of sea.
