摘要:
A sleeve 2e having the length of the side surface thereof made longer at a position away from the compressor outlet 11 is connected to the upstream-side end of an external cylinder 2c. By this sleeve 2e, compressed air flowing along the inside wall surface of a casing 4 flows, making a turn, in a space between the sleeve 2e and the inside wall surface of the casing 4, thereby providing the compressed air flow being introduced from the sleeve 2e to the external cylinder 2c with uniformity.

By installing a cylinder 53 having a bell-mouth construction to the downstream side of a combustor basket 2a, compressed air flowing between the combustor basket 2a and an external cylinder 2c is throttled. In addition, by having a cross section of the downstream-side end surface of the cylinder 53 shaped in a semicircle and providing a back surface wall 2d having a curvature being equivalent to a curvature of the semicircular curved surface, compressed air flow making 180 degrees turn can be made uniform and free from disturbance.

By installing a cylinder 53x having a bell-mouth construction to the downstream side of a combustor basket 2a and by providing different level to the downstream-side end of the cylinder 53x, notches 60 are constructed. The notches 60 form fixed vortices in the compressed air, and the vortices enable the compressed air to determine the flow direction thereof so as to flow toward the tips of the main nozzles 22.
摘要:
A punched metal plate 51 is constructed so as to be in a ring shape covering a space between the outside wall of the combustor basket 2a and the inside wall of the external cylinder 2c and at the same time is constructed to be a perforated plate having a plurality of holes. In addition, ribs 52 are provided in a radial pattern against the axis of a combustor in a manner that both ends of a rib 52 are in contact with the outside wall of the combustor basket 2a and the inside wall of the external cylinder 2c. Additionally, ribs 52 are provided in a plural number, and the plurality of ribs 52 are arranged so as to be equally spaced in the circumferential direction of a combustor and connected to the external cylinder 2c, thereby supporting the combustor basket 2a.

摘要:
In a combustor of a gas turbine which has a pilot nozzle being installed to the center of the axis of a combustor basket and a plurality of main nozzles being installed to the vicinity of the pilot nozzle and provided with a premixing tool on the outer circumference thereof, wherein, fuel being injected as air-fuel pre-mixture from the main nozzle into the interior of a transition piece forming a combustion chamber downstream of the combustor basket is ignited by diffusion flame being generated by the pilot nozzle in the transition piece so as to generate a premixed flame in the transition piece, wherein combustion is performed by a part of the plurality of main nozzles from start-up until a predetermined load rate and then performed by adding the remaining portion of the plurality of main nozzles when the predetermined load rate is exceeded.
摘要:
A secondary battery is comprised of a positive electrode having a material intercalating alkali earth metal ions or lanthanoid metal ions reversibly, a negative electrode having a carbon composition intercalating those ions reversibly and an electrolyte having an organic solvent and a solute. The solute includes an alkali earth metal salt or a lanthanoid metal salt. The organic solvent is selected from a group comprising ethylene carbonate (EC), dimethyl carbonate (DMC) and vinylene carbonate (VC). The carbon composition is selected from a group comprising coke, refined coke with 99% or more purity, organic compound produced by calcined cellulose, graphite and glassy carbon.
