摘要： A combustor comprises a liquid fuel nozzle for injecting liquid fuel to a combustion chamber, and an air supply nozzle disposed around the liquid fuel nozzle and injecting air. The air supply nozzle is disposed such that air is injected from the air supply nozzle in a direction toward an axis of the liquid fuel nozzle. A space is formed around an outlet of the liquid fuel nozzle, through which the liquid fuel is injected from the liquid fuel nozzle to the combustion chamber, upstream of a distal end of the outlet in a direction in which the liquid fuel is injected. Carbonaceous deposits on surrounding surfaces of the outlet of the liquid fuel nozzle can be suppressed regardless of the operating conditions of a combustor.

摘要： A gas turbine system burning heavy-oil modified fuel and a method of operating the gas turbine system, which covers from a stage of modifying heavy oil and producing gas turbine fuel to a stage of operating a gas turbine, including startup, ordinary shutdown and emergency shutdown of the gas turbine. The gas turbine system burning heavy-oil modified fuel comprises a reactor for mixing heavy oil and water to cause reaction, thereby separating and removing a heavy component from the heavy oil, a gas-liquid separator for separating hydrocarbon gas and modified oil obtained in the reactor from each other, a gas turbine combustor for burning the hydrocarbon gas supplied from the gas-liquid separator, and a gas turbine driven by combustion gas produced in the gas turbine combustor. The system further comprises another line for extracting the hydrocarbon gas externally of a relevant system region. The other line is branched from a line for supplying the hydrocarbon gas from the gas-liquid separator to the gas turbine combustor.
