PROBLEM TO BE SOLVED: To recover and make effective use of waste energy having relatively low temperature.;SOLUTION: A system for recovering and utilizing the waste energy includes: a steam reformer 1 for subjecting one or more of methanol, ethanol and dimethyl ether as a feed gas to steam reforming by using steam and exhaust heat; a gas mixer 3 for mixing part or all of reformed product gas produced in the steam reformer 1 with a hydrocarbon gas; and a fuel supplying unit (a mixed gas supplying pipe 3a) for supplying the mixed gas obtained by the gas mixer 3 as a fuel. A method for recovering and utilizing the waste energy includes: subjecting the one or more of methanol, ethanol and dimethyl ether to steam reforming in the steam reformer 1 by using the exhaust heat having low temperature, or at 250-450°C; mixing the part or all of the reformed product gas with the hydrocarbon gas by the gas mixer 3; and enabling the mixed gas to be supplied at the fuel supplying unit as the fuel.;COPYRIGHT: (C)2012,JPO&INPIT
