摘要： PURPOSE:To image and measure the density values of plural components of an intermediate product produced in an elementary reaction process of combustion instantaneously at the same time by synthesizing laser light beams which match the absorption spectrum wavelength of a body to measured together, putting the light beams into a sheet shape and irradiating the body to be measured with the light beams. CONSTITUTION:The laser light beams from dye lasers 12 and 13 are tuned and mixed through a mirror 14, a dichroic mirror 15, a cylindrical lens system 16 and a beam splitter 17 so as to match absorption spectra of plural materials to be measured at the same time, and then the beams are changed from circular section to sheet section, and the body to be measured is irradiated with the beams. Consequently, materials in the section absorb light energy to rise in energy potential from base states to excited states and then return to the original base states in short times to emit fluorescent light. The fluorescent light is observed on a lower-wavelength side than the absorption spectrum wavelength. Those two kinds of the fluorescent light are observed by a high-sensitivity camera device 24 arranged at right angles to the tomographic surface. The fluorescent light beams are separated by an optical filter 18, so simultaneous video formation becomes possible.

摘要： PURPOSE:To permit the evaluation of burning property by a method wherein the spectrum of a specified chemical kind is extracted from the spectrum of light emitted from flame and the picture visualizing means of the distribution of the strength of the spectrum is provided while a means fore detecting the igniting and extinguishing of the flame in a high speed is provided in the title device. CONSTITUTION:A quartz window 12 is provided at the rear stream part of a main chamber liner wall 11 in order to catch the pattern of second stage flame 13 while an observation probe 14 is attached to a casing 10 opposing to the quartz window 12. The observation probe 14 includes an image fiber 15, an optical filter 16 is arranged at the outlet end of the fiber, an image on the fluorescent screen of a microchannel plate (MCP) 18 is split by a beam splitter 19 while one of the split images is imaged on the take-up element of a CCD camera through a relay lens 20 and is displayed by a picture processor 22 by coloring it. The light of the other image is imaged by another lens 23 at the inlet end of an optical fiber 24 while the other end of the fiber 24 is amplified by a photomultiplier tube 25 and is monitored employing an oscilloscope 26 and the like. When the existence of the flame is judged, the output of the photomultiplier tube 25 is introduced into a comparator 27 to judge it by comparing it with a threshold value. According to this method, the spread of a reaction area and/or unstable behavior of burning reaction can be known.

摘要： PURPOSE:To obtain a gas turbine combustor of high stability at all times and of low NOx discharge by shifting the control point setting of the swirler valve aperture according to the humidity of the detected inflow air. CONSTITUTION:Air 1 is pressed by a compressor 2, led into a combustion casing 3 and flowed from the primary and secondary stage combustor liners 4, 5 and the air hole of the secondary premixing swirler 6 into the primary and secondary stage combustion chambers 7, 8. F1 fuel 9 of the primary stage is injected out of a nozzle 10 into the combustion chamber and diffusedly combusted. F2 fuel 11 of the secondary stage is injected out of a nozzle 12, forms mixed air with the air while flowing inside the premixing swirler 6, flowed into the combustion chamber 8 and premixedly combusted. While the turbine load is small, only the F1 fuel is combusted, and when the load reaches the fixed value, the fuel is charged also at the secondary stage. The aperture of a swirler valve 15 is controlled by means of a valve control device 17 and a valve driving device 16 in response to the increase and decrease of the F2 fuel, and the fuel air ratio and the spray velocity of the mixed air at the exit of the swirler 6 are controlled to the appropriate values.

摘要： PURPOSE:To suppress the generation of NOx and CO by introducing residual air restricted from flowing into a second stage combustion air flow passage into a second stage combustion chamber through a bypass, in the two-staged firing burner of a gas turbine. CONSTITUTION:Air 21 in first and second stages is divided into air 23 passing a slide ring 21 and a second stage air inlet part 22 and air 24 supplied to a first stage combustion chamber. At the time of charging air in the second stage combustion, the slide ring 18 is shifted to the lefthand to throttle the flow rate of the second stage air 23. At this time, by the shift of the slide ring 13 to the lefthand, the effective area of an air inlet port of the bypass 20 is increased. Therefore, air throttled with the reduction of the area of the second stage air passage inlet 22 becomes air 26 passing the bypass 20, which is introduced into a second stage combustion chamber 13. By this arrangement, the generation of NOx and CO can be suppressed without affecting the first stage combustion.

摘要： PURPOSE:To reduce NOX, by a method wherein a fuel nozzle is penetrated through the closed end of the outer cylinder of a combustion chamber and the direction of air stream, supplied to the circumference of the fuel nozzle, is biased so as to be asymmetrical with respect to the central axis of the nozzle. CONSTITUTION:A first stage fuel nozzle 9 is attached to the closed end of the outer cylinder of a combustion chamber. An opening 32 for supplying air to the circumference of the nozzle 9 is provided. An air deflecting plate 33 is attached between an inner wall 23 in front of a liner cap 31 and an inner cylinder 13 to bias air stream 34 from the opening 32 toward the side of the inner cylinder 13 at all times. The air stream around the nozzle and a flame 35 are rolled by the ejector effect of the biased airflow whereby eddy current type flame retaining stream 29 is formed. According to this method, stabilized combustion may be realized and NOX may be reduced.

摘要： PURPOSE:To decrease a flow amount of sealing fluid, which flows from the center part of a rotary unit to the periphery through a clearance between the rotary unit and a stationary unit, by providing a deflection plate deflecting the sealing fluid to a side of the stationary unit in an inlet part of the sealing fluid into said clearance. CONSTITUTION:To prevent high temperature main flow gas 50 from intruding between the bottom part of a moving blade 20, wheel 10 and a nozzle diaphragm 30 and a partitioning casing 40, sealing air 60 is allowed to flow from the center part of a rotor to the periphery. Deflection plates 100 are provided to inlet parts of the sealing air, and a flow of the sealing air is deflected in the direction to a side of the nozzle diaphragm 30 and the casing 40, then the generation of a flow internally in the radial direction due to rotary motion of the wheel 10 is prevented when the sealing air flows to the periphery.
