摘要： PROBLEM TO BE SOLVED: To enable use of the heavy oil for efficient power generating device by mixing a heavy oil component and a light oil component at a specified valve or less of dynamic viscosity, transferring the mixture oil component to a power generating device, and separating the mixture oil component to the light oil component and the heavy oil component, and burning the light oil component in a gas turbine of the power generating device, and burning the heavy oil component in a boiler of the power generating device. SOLUTION: A mixing device 1 mixes a light oil component and a heavy oil component at 800 centistokes or less of dynamic viscosity, and dynamic viscosity of the heavy oil component is lowered so as to facilitate the transference by mixing the light oil component and the heavy oil component. A transfer system 2 transfers the mixture oil to a power generating device, and a separation means 3 separates the mixture to the light oil component and the heavy oil component with the separating operation. The light oil components separated by the separating device 3 are fed to a gas turbine 5, and the heavy oil components are fed to an exhaust gas boiler 6. Power is generated by burning these oil components. Since the harmful material is transferred to the heavy oil component, damage to the gas turbines can be prevented.

摘要： PROBLEM TO BE SOLVED: To improve the power generating efficiency while effectively utilizing the high-temperature exhaust gas to be generated in a heavy fuel oil heating and decomposing device or a raw oil heating and fractional distillation device by providing a route for feeding the exhaust gas generated by the combustion of the light gas from a heavy fuel oil decomposing unit in a heavy fuel oil heating and decomposing device to a boiler. SOLUTION: A heavy fuel oil decomposing unit (raw oil fractional distillation unit) including a heavy fuel oil heating and decomposing device (raw oil heating and fractional distillation device) 1, a gas turbine 2 and a boiler 3 are included as main equipment. Especially, a line 20 for feeding the exhaust gas to be generated by combustion of the light gas from the raw oil fractional distillation unit in the raw oil heating and fractional distillation device 1 to a boiler 3 is provided. Heat recovery in the boiler 3 is aimed at by this line 20. The exhaust gas from the raw oil heating and fractional distillation device 1 maintains the predetermined temperature, and efficiency can be remarkably raised by recovering the heat. Furthermore, since a desulfurizer and an NOx removal system in the downstream of the boiler 3 can be utilized, necessity of providing other desulfurizer and NOx removal system dedicated to the raw oil heating and fractional distillation device 1 is eliminated.
