  • Publication number: 20120031103
    Abstract: A fuel control device and method of a gas turbine combustor, for advanced humid air turbines, in which plural combustion units comprising plural fuel nozzles for supplying fuel and plural air nozzles for supplying air for combustion are provided. A part of the plural combustion units are more excellent in flame stabilizing performance than the other combustion units. A fuel ratio, at which fuel is fed to the part of the combustion units is set on the basis of internal temperature of the humidification tower and internal pressure of the humidification tower to control a flow ratio of the fuel fed to the plural combustion units.

  • Publication number: 20110076628
    Abstract: This invention is directed to supply a combustor having a structure that reduces NOx emissions while maintaining combustion stability. The combustor has a chamber into which fuel and air are supplied. An air hole plate having a plurality of air holes upstream of the chamber is also disclosed, and fuel nozzles supplying fuel to the air holes of the air hole plate are further disclosed. In the combustor, a center of a chamber-side of the air hole plate is closer to the chamber than exits of outermost peripheral air holes.

  • Patent number: 4683258
    Abstract: Disclosed herein is an agent for absorbing and releasing water vapor, which comprises a homopolymer of at least one monomer selected from specific N-alkyl- or N-alkylene-substituted acrylamides and methacrylamides, a copolymer of two or more of the acrylamides and methacrylamides, a copolymer of said at least one monomer with one or more monomers other than the acrylamides and methacrylamides and copolymerizable therewith, or a water-insolubilized product of the homopolymer or either one of the copolymers. The above agent has broad utility for humidity contol of gases, humidity control in green houses and prevention of fogging on surfaces of transparent materials, as humidity sensors and dew sensors, etc.
