PROBLEM TO BE SOLVED: To provide a reformed fuel combustion gas turbine and an oil-heating method preventing a heat-transfer pipe at a heavy oil side from being corroded and broken, and the leakage of heavy oil from the heat-transfer pipe. SOLUTION: In the reformed fuel combustion gas turbine device equipped with the gas turbine operated with reformed fuel which is reformed into light oil from heavy oil by raising the temperature and pressure of the heavy oil and mixing it with supercritical water, the heat-transfer pipe of a double-type structure is installed in a heat recovery steam generator installed downstream of the gas turbine, the heavy oil is fed into an inside tube of the double tube, and non-combustible oil is fed into the outside of the double tube. As a result, the reformed fuel combustion gas turbine device and the oil-heating method improved in reliability can be provided. COPYRIGHT: (C)2004,JPO
