Abstract
A gas turbine which can be easily employed in an area where it is hard to obtain a sufficient amount of water, such as an isolated island. Heated and pressurized heavy oil and water in a supercritical state are mixed with each other in a modifying unit to produce fuel-purpose modified oil. The fuel-purpose modified oil is depressurized by a depressurizing valve. Due to a temperature fall caused by adiabatic expansion with the depressurization, the fuel-purpose modified oil is brought into a two-phase state where moisture is in a gas phase (steam) and modified oil is in a liquid phase. The fuel-purpose modified oil is separated into the steam and the modified oil by a gas-liquid separator. The separated steam is condensed to water in a condenser and returned to a water supply line. The modified oil in the liquid phase is supplied to a combustor, thereby driving a gas turbine.
