Publication number: 20060032211Abstract: Disclosed is a gas turbine power generating system capable of achieving a high output power and a high power generating efficiency under conditions with a small amount of supplied water and less change in design of a gas turbine. A fine water droplet spraying apparatus (11) is disposed in a suction air chamber (22) on the upstream side of an air compressor (2), and a moisture adding apparatus (7) for adding moisture to high pressure air supplied from the compressor (2) is disposed. A regenerator (5) for heating the air to which moisture has been added by using gas turbine exhaust gas a heat source is also provided. With this configuration, there can be obtain an effect of reducing a power for the compressor (2) and an effect of increasing the output power due to addition of moisture to air (20) for combustion. Further, since the used amount of fuel is reduced by adopting a regenerating cycle, the power generating efficiency is improved.Type: ApplicationFiled: October 20, 2005Publication date: February 16, 2006Inventors: Shigeo Hatamiya, Masahiko Yamagishi, Osamu Yokomizo, Yoshiki Noguchi, Moriaki Tsukamoto

Publication number: 20050040081Abstract: 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.Type: ApplicationFiled: August 4, 2004Publication date: February 24, 2005Inventors: Hirokazu Takahashi, Shinichi Inage, Nobuyuki Hokari, Masahiko Yamagishi, Akinori Hayashi, Osami Yokota, Youji Ishibashi
