Abstract: A stereoscopic image display apparatus of this invention includes a half mirror having a ½ wavelength plate and a half mirror layer. Therefore, a direction of polarization of light incident on a surface of a transmission side of the half mirror can be rotated and emitted. This can be manufactured at lower manufacturing cost than a construction having the ½ wavelength plate on the front display plane of one of the two image display devices with linear polarization plates having the same polarizing direction, or preparing two image display devices with linear polarization plates having different polarizing directions. A high-quality stereoscopic image can be observed by adjusting the orders and positions of sub-pixel colors of the two image display devices at the time of composition and display through the half mirror.

Abstract: 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.

Abstract: 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.

Abstract: A heavy oil reforming system includes a reforming preheater raising the temperature of a mixed fluid comprising a high pressure heavy oil and high pressure steam up to a temperature for reforming reaction. The mixed fluid having been heated up to the temperature for reforming reaction is introduced into a reformer kept at the temperature for reforming reaction and thereby the heavy oil is reformed. This reforming system allows the attainment of a residence time of 1 to 10 min necessary for reforming in a uniform or nearly uniform temperature field, thereby implementing the manufacturing of reformed fuels from a large volume of heavy oil.

Abstract: In a method for producing gas turbine fuel through the step of modifying heavy fuel oil with the use of an asphaltene-insoluble solvent, the utilization factor of the heavy fuel oil usable as gas turbine fuel is increased by making asphaltene selectively removable. A solvent having a specific inductive capacity in the range of 1.4 to 2.0 is used as the asphaltene-insoluble solvent. In particular, water controlled in temperature and pressure so as to have a specific inductive capacity in the above range is used as the asphaltene-insoluble solvent. By using such a solvent, an asphaltene component contained in the heavy fuel oil can be selectively removed and power generation can be performed while utilizing 95% or more of the heavy fuel oil.

Abstract: The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.

Abstract: A gas turbine combustor comprises a premixed combustion burner disposed on the periphery of a pilot burner, an approximately cylindrical combustor liner disposed on the downstream side of the premixed combustion burner, which defines a combustion chamber in the liner. The gas turbine combustor is characterized by further comprising flame stabilizers radially disposed at the exit of the premixed combustion burner, and a fuel injection means with which the pilot burner is provided injects at least one of gas fuel and liquid fuel, in which a plurality of air nozzles are provided which are located outside the pilot burner and inside the premixed combustion burner, and which spout out air into the combustion chamber. Adequate combustion can be accomplished with a combustor which is capable of using gas fuel and liquid fuel, and at the same time, NOx can be reduced.
