摘要： In a gas turbine that generates rotational power by supplying fuel to compressed air compressed by a compressor and burning the fuel in a combustor and supplying resultant combustion gas to a turbine, a circumferential distance starting from a leading edge of a turbine first stage nozzle toward a trailing edge side of the first stage nozzle and ending at center of transition pieces of such combustors that are adjacent in a circumferential direction is set relative to a circumferential pitch of such first stage nozzles within a range of 0.05≦S/P≦0.15, and an axial distance between a leading edge of the first stage nozzle and a transition piece rear end of the combustor is set relative to the circumferential pitch of the first stage nozzles within a range of 0.00≦L/P≦0.13. By improving the relative position of a transition piece of the combustor and the first stage nozzle, both suppression of inner pressure fluctuations of the combustor and enhancement in aerodynamic efficiency can be achieved.

摘要： A steam-cooled type gas turbine has flange contact surfaces between adjacent rotor disks in which buffering sheets such as gaskets and the like can not be inserted. Further, the contact surfaces have a large diameter, making it difficult or impossible to ensure sufficient surface contact pressure for sealing. Yet preventing the leakage of coolant steam from these flange contact surfaces presents a very important problem. The present invention provides a seal structure for flange contact surfaces of a gas turbine which can enhance the sealability at these portions. The seal structure for flange contact surfaces includes a plurality of labyrinth-like grooves (8) which are formed in at least one of the flange contact surfaces (7). The seal structure of the present invention provides a gas turbine with high reliability and enhanced sealability. Further, a high surface contact pressure is obtained by reducing the area of the flange contact surfaces.

摘要： Carbonyl halide is produced from carbon monoxide and halogen produced from the electrochemical conversion of anhydrous hydrogen halide. Both the oxidation of anhydrous hydrogen halide and the formation of carbonyl halide are carried out in the anode-compartment of an electrochemical cell. This reduces the equipment and thus the capital investment necessary for carrying out these reactions. Moreover, no catalyst is needed to form halogen and subsequently make carbonyl halide, as in the prior art. In addition, the health hazards associated with making a carbonyl halide, such as phosgene, at high temperatures from chlorinated hydrocarbons with atmospheric oxygen are virtually eliminated. Furthermore, the halogen produced as a result of the oxidation of anhydrous hydrogen halide are dry, thereby eliminating the need for a preheater before the halogen is reacted with carbon monoxide. Thus, with the present invention, carbonyl halide may be produced more easily, more safely and more inexpensively as compared to prior art processes.

摘要： In a steam cooling type gas turbine, a sealing structure for improving sealing performance between an interior of a rotor and a gas path of a turbine section which performs inter-disk sealing such that leakage of cooling steam and self-induced vibration of a baffle plate are prevented. A groove is formed along a circumferential direction in an end face of at least one of disk lands which protrude in opposition to each other between adjacent rotor disks, and an annular sealing member having an interior space is disposed in a sandwiched fashion, being brought into contact under pressure with an inner wall surface of the groove and an end face of the other disk land, or alternatively, an inner wall surface of a groove formed in the other disk land to thereby realize the inter-disk sealing structure for the gas turbine. Upon rotation of the turbine, sealing surface pressure is increased by centrifugal force to thereby reliably maintain sealing between the disks of the gas turbine, and the sealing performance in the gas turbine is improved.

摘要： A sealing device in a gas turbine that uses steam for cooling high temperature portions of the gas turbine and then recovers the steam. The sealing device prevents the steam from leaking at a spindle bolt portion of the turbine disc (8). The spindle bolt (1) passes through a seal hole (4) formed in the turbine disc (8). The sealing device is disposed in the seal hole and includes a seal piece (3), having a smaller coefficient of linear expansion relative to the spindle bolt (1), and a seal piece cover (5) for covering the seal piece (3). A pressure hole is bored through the seal piece cover (5) such that high pressure side steam pressure is introduced through the pressure hole (6) and into an inner side of the seal piece cover (5) so that the seal piece (3) is urged into contact with a sheet surface (7) of the seal hole (4).
