摘要： PURPOSE:To make stable combustion in a combustion unit for gas turbine of a gaseoud fuel two-stage combustion type by a method wherein second-stage combustion air is extracted through a flow rate adjusting means to the non- combustion side from between the second-stage combustion air intake port and the second-stage fuel nozzle. CONSTITUTION:An extracting port 41 is formed between the air from the second air supplying port 20 and the second-stage fuel mixing part 33, a part of the second-stage air is controlled by a flow rate adjusting valve 100 and then extracted. This flow rate adjusting valve 100 is controlled by a controller 101 in accordance with load. With this arrangement, the air flow rate is extracted to the second-stage from the time of feeding of second-stage combustion volume and thus a proper volume can be attained in respect to the second-stage fuel and so stable combustion can always be maintained.

摘要： PURPOSE:To improve inspection accuracy and to decrease man-hours, by detecting the true damaged state of a metallic parent material beneath a coating layer. CONSTITUTION:A ring 11 is provided at the inside of a sleeve 9. A thin plate 13, whose material is the same as that of the ring 11 and thickness is about 1mm. or less, is stuck to the inner surface of the ring by spot welding and the like. A coating layer 16 comprising a metal coating layer 14 and ceramic coating layer 15, is further provided on the surface of the plate 13. When a stage requiring inspection is reached after usage in an actual machine for a long time under this state, at first, whether the coating layer 16 is exfoliated or not is inspected. At the next stage of inspection, the examination of a metallic parent material is required. In the examination of the ring 11 located in the inside, the protruded part and the like of the thin plate 13, which are provided beforehand, are held by a tool such as a pair of nippers, and the thin plate 13 is removed from the ring 11. The coating layer 16 can be removed simultaneously. Thus the coating layer can be readily removed, the surface of the parent material of the ring 11 appears and the liquid penetrant examination can be performed.

摘要： A method of starting a gas turbine plant, which plant has at least one combustor including a primary combustion chamber into which primary fuel nozzles open and a secondary combustion chamber into which secondary fuel nozzles open, a compressor for supplying the combustor with compressed combustion air, and a gas turbine driven by the combustion gas generated in the combustor and adapted to drive a load such as an electric power generator. When the gas turbine is being accelerated to a rated speed or while the load is still below a normal load range, a fuel is supplied only to the primary fuel nozzle, whereas, in other loaded operation range, the fuel is supplied to both the primary and secondary fuel nozzles. Before the fuel supply to the secondary fuel nozzles is commenced, a part of the compressed air is bled through at least one air bleed pipe leading from the compressor and having an air bleed valve. The air bleed valve is controlled in such a manner that the opening degree thereof is maximized when the fuel supply to the secondary fuel nozzles is commenced and is progressively decreased in accordance with the increase of the load such as to become substantially zero when the load has been increased to the normal load range.

摘要： PURPOSE:To reduce a harmful component in exhaust gas from a turbine when it is partly loaded, by changing a mounting angle of a variable stationary blade in a compressor so that a flow proportion of fuel to air may be controlled to a fixed range. CONSTITUTION:A flow of fuel F fed to a combustor 4 is measured by a detector 7, and its signal 8 is fed to a control device 9. Here a mounting angle control signal 10 for a variable stationary blade 2 provided in an axial compressor 1 is calculated being fed to a variable stationary blade driving gear 3 so that fuel-air ratio F/A may be controlled to a fixed value. In this way, a turbine, even when it is partly loaded, enables a harmful component in exhaust gas to be reduced by controlling the fuel-air ratio within a fixed range.

摘要： PURPOSE:To improve the combustion property and the reliability of the combustor by a method wherein the flow amounts of primary and secondary air, introduced into a head combustion chamber and a rear combustion chamber, are controlled so as to meet the amounts of primary and secondary fuels to reduce NOx in exhaust gas and restrict generation of CO and unburnt constituent within the wide operating range of the gas turbine. CONSTITUTION:The secondary fuel 49 is injected from a plurality of fuel nozzles 40 toward a secondary air ports 39 opened at a plurality of places and is mixed with secondary air stream 30 to supply it into the rear combustion chamber 11 and form a premixed flame 43. The primary fuel 44 is introduced from a plurality of primary fuel nozzles 46 into the head combustion chamber 7 and forms diluted low-temperature combustion flame 48 under being mixed with the air stream 24 or conditioned primary air stream 47. Adjusting valves 33, 42 are operated so that the flow amount of the primary fuel 44 becomes a constant ratio to air by the change of load by a proportional operator 50 adjusting the ratio of fuel to air. On the other hand, the secondary fuel 49 is introduced with a flow amount meeting the reduced part of the primary fuel 44 and the adjusting valves 41, 32 are operated so that the ratio of fuel to air, in which it is within the range of combustion and not generating CO or unburnt constituents, is obtained.
