摘要： PURPOSE:To clean an intake air filter in a simple and inexpensive manner by cooling bleed air from a gas turbine compressor by means of a cooling device provided to an air intake device of the gas turbine so as to use it as pulse air. CONSTITUTION:A cooling device 20 which is composed of a curved pipe for heat exchanging, is provided in a flow path of a clean air 4 in an air intake device 1, and the cooling device 20 is arranged between a bleed air pipe 18 from a gas turbine compressor 6 and a pulse air pipe 5. The time when the internal pressure in the air intake device 1 is lowered, is detected by a difference pressure detecting switch 9, and a solenoid value 12 is operated by control means 14 and 11 so as to inject pulse air 16 into an intake filter 3 for blowing deposits off. In this case, bleed air from the gas turbine compressor 6 is cooled by allowing the cooling device 20 to effect heat-exchanging with clean air 4 so as to inject the cooled bleed air against the intake filter 3.

摘要： PROBLEM TO BE SOLVED: To effectively eliminate a noise without using a noise absorbing material in a noise eliminating splitter arranged in an exhaust duct and so on, by extensively setting the rate of hole area of each noise absorbing hole against the surface area of each noise eliminating splitter main body by a predetermined rate in an intermediate part against an exhaust upstream part and an exhaust downstream part. SOLUTION: A noise eliminator comprises a plurality of noise eliminating splitters 4. Each noise eliminating splitter 4 is formed of a noise eliminating splitter main body 5, and partitioning walls 7 by which the inside of the main body 5 is partitioned into a plurality of noise eliminating chambers 6, and many noise absorbing holes 10, 11 are formed on the surfaces of both side walls 8 of the main body 5. The rates of hole areas of respective noise absorbing holes 10, 11 are set to be approximately 30% in an intermediate part 12, and approximately 3% in an upstream part 13 and a downstream part 14. The noise eliminator 1 is made to serve as both an extended chamber type noise eliminating splitters in which the passage cross sectional area of an acoustic wave is changed and resonance absorption noise eliminating splitters by which the acoustic wave is absorbed and canceled, therefore, a noise can be enough eliminated without filling a noise absorbing material into the inside of the main body 5.

摘要： PURPOSE:To prevent a big accident due to erroneous operation of dampers in such a way that at the same time as a pressure detector is installed for detecting the internal pressure in an exhaust duct, a relief damper is provided. CONSTITUTION:In concurrence of installing a relief damper 23 and a differential pressure switch 22 between an exhaust duct 7 and a bypass stack 9 with separately installing a pressure switch 21, pressure is detected in the exhaust duct 7, an interlock is assembled such as to stop fuel control signal 20 by duct internal pressure abnormal signal 29 and a gas turbine by duct internal pressure height alarm 27. By said constitution, though abnormality of dampers 8, 10 actuates so as to stop the turbine, the turbine continues to make rotation, the internal pressure rises in the duct 7, the differential pressure switch 22 gives signal 30 running through an arithmetic operator 16 and relief damper opening signal 26 actuates an actuator 24, which opens a relief damper 23, to discharge gas turbine exhaust out to the atmosphere. This prevents the system from an accident.

摘要： PURPOSE: To rectify exhaust gas uniformly as checking an increase in pressure loss as well as to improve denitration efficiency ever so better, by varying a numerical aperture of a rectifying grid in accord with exhaust gas velocity distribution.
CONSTITUTION: An ammonia injection part for denitration is installed in an exhaust duct 12. A rectifying grid 15a is installed at the upstream side of this ammonia injection part. A numerical aperture of this rectifying grid 15a is adjusted to the velocity distribution of exhaust gas flowing in the duct 12 and made so as to be varied inside a flow passage section. Doing like this, a spot where the velocity is high is made small in the numerical aperture whereby the flow section can be made into uniform velocity distribution as a whole. Thus, ammonia is uniformly touchable to the exhaust gas.

摘要： PURPOSE:To reduce installation area and cut down the cost of constructing the building by arranging gas flow of both burner and regenerator to be horizontal and at a right angle to the body of the turbine. CONSTITUTION:The turbine enclosure 17 is formed to enclose the compressor wheel chamber 13, the turbine wheel chamber 14, the turbine intermediate casing 15 and the suction air plenum 16, etc., a burner enclosure 20 is attached to the turbine enclosure 17 to be freely attached and detached, in the form to surround the outer cylinder of the burner 18. Further, a horiozontal type regenerator 22 is connected to the turbine exhaust port 23 so that its flow derection may be perpendicular to the turbine body 11, and all the accessories other than covered by the turbine enclosure 17 are enclosed by the outer cover 30. By this arrangement whole equipment of the turbine can be installed compactly as a package type, and units sent from the manufacturer's plant per each enclose can be immediately assembled as it is on the site, and operated.

摘要： PROBLEM TO BE SOLVED: To prevent the generation of damage of a telescopic heat insulating material, and prolong the lifetime by preventing the generation of negative pressure in an exposed part of the telescopic heat insulating material so that fatigue such as a vibration due to a vortex and negative pressure is not applied to the exposed part. SOLUTION: A vortex, which is generated by a high temperature fluid A at a part of an open part 51, is remarkably reduced at a separated position in the downstream of a telescopic joint unit 21. A part of the high temperature fluid A, which flows inside of a sleeve 50, always flows to the open part 51a through a ventilation hole 52 so as to reduce the negative pressure, and the spiral B is disturbed for reduction. Since negative pressure is not generated in an exposed part 24a of the telescopic heat insulation material 24 and fatigue such as a vibration due to the vortex and the negative pressure is not applied to the exposed part 24a, generation of damage of the telescopic heat insulating material 24 is prevented so as to prolong the lifetime.

摘要： PURPOSE:To prevent explosion of a gas turbine by installing a ventilation fan on the roof of an auxiliary machinery chamber and sending pressurized air into the gas turbine package. CONSTITUTION:A gas turbine auxiliary machinery chamber 1 and a gas turbine chamber 2 are enclosed with metal sheets so as to make the gas turbine a package-type one. On the roof of the chamber 1, a ventilation fan 5 is installed, and pressurized air is sent into the package through air ducts 9A, 9B. Through this arrangement, inner room diffusion is executed on the basis of forced convection in which blown air runs against the bottom part of the package and ascends again. Even if gas leakage occurs within the package, therefore, the gas can be pushed out of it, and explosion can be prevented.
