NOVELTY - The gasification power-generation equipment (10) is provided at the side of a gasification installation (20). The equipment has a gas-engine electric-power-generation unit (11) which burns a supplementary fuel (F) and thermal-decomposition gas from the installation, and generates electric power (D). Sewage sludge (A) is heated by the heat of waste gas (G) produced from the gas-engine electric-power-generation unit.    USE - For gasification power-generation from sewage sludge (claimed).    ADVANTAGE - The equipment recovers the possession energy of sewage sludge as electric power with high efficiency, suppressing the processing cost. Generation of mechanical loss in the fuel-formation apparatus is suppressed. New installations, such as combustion apparatus, are not required for heating the sewage sludge in the drier. The heat amount of fuel gas supplied is stabilized, and stabilization of electric-power-generation efficiency and output is achieved. The sewage sludge is dry-processed with high efficiency, and the combustion efficiency in gas-engine electric-power-generation unit is improved. The heat of waste gas is efficiently transferred to the drier, maintaining the high temperature. The load acting on the gas engine is suppressed.    DETAILED DESCRIPTION - The gasification power-generation equipment (10) is provided at the side of a gasification installation (20) of sewage sludge (A). The gasification installation is equipped with a drier (21) which heats and dries sewage sludge, and a gasifier (22) which thermally decomposes the dried sewage sludge and produces thermal-decomposition gas (E). The equipment has a gas-engine electric-power-generation unit (11) which burns the thermal-decomposition gas and a supplementary fuel (F), and generates electric power (D). The sewage sludge in the drier is heated by the heat of waste gas (G) produced from the gas-engine electric-power-generation unit. An INDEPENDENT CLAIM is included for gasification power-generation method.
