摘要： PURPOSE:To remarkably reduce the consumption of water at the time of a pressure test and to greatly reduce the man-hours for operation by charging a water amount exclusion member which substitutes for the volume of a part of injection water and has smaller specific gravity than water in a pressure container. CONSTITUTION:Plural spherical bodies 23 for gas charging are formed in the pressure container while linked with one another by communicating pipes 25, which are connected to a gas cylinder 7. When the pressure test is taken, the water amount exclusion member 2 is charged in the pressure container 1 and then the communicating pipes 25 and sealed from the pressure container 1 with water and connected to the gas cylinder 7 through a gas pressure origin valve 9, which is opened until the bodies 23 for gas charging swell as specified to apply pressure with the gas of the gas cylinder 7. In this case, the water amount exclusion member 2 has no variation in volume because of pressure proof structure, and water for hydraulic pressure can be reduce greatly to reduce and shorten the operation man-hours and time for water filling and water discharging and also facilitate the operation, thereby reducing the cost.

摘要： PURPOSE:To provide a gas turbine combustion device in which an excessive occurrence of combustion vibration can be restricted and a stable combustion can be realized with an operating range including a combustion condition capable of reducing the discharged NOx. CONSTITUTION:A premixing burner 90 having a flame holder 3 is installed adjacent to a circulating flow burner 80 and a premixing gas injection port of the premixing burner 90 is provided with a projection 15. As a load at the gas turbine is increased, a rate of fuel supplying amount for the premixing burner is increased to restrict an increasing of the discharged NOx. Even if a flow rate of fuel at the circulating flow burner 80 is substantially varied, a circulation flow of high temperature formed at a downstream side of the projection 15 arranged at an inner circumferential wall surface of a premixing device 4 becomes a flame holding region, so that the flame is stably formed. With such an arrangement as above, combustion at the circulating flow burner can be stably held within all the operating ranges of the gas turbine combustion device and then occurrence of severe combustion vibration can be restricted.

摘要： PURPOSE:To provide a small and light measurement device attachably/ detachably mounted on a trolley service vehicle and running at a low speed, for measuring the amount of wear, etc., of a trolley line. CONSTITUTION:The device consists of a rotation mechanism 7 which allows rotation in both the horizontal and vertical directions and contains a movable arm 73 energized upward by a spring, a sensor part 8, attached to the tip of the arm 73, which follows changes in level and right/left deviation of the trolley line 1 and its bent part and contains a light quantity type sensor, and a data processor part 9 which processes the photo-detected signal at the sensor and outputs measurement data of remaining diameter. Further, measurement function for right/left deviation quantity and position in level of the trolley line 1 is added. As a result it can be manufactured at a low cost and can be utilized for trolley line measurement in various sections.

摘要： PURPOSE:To enable attainment of combustion of low NOx which is stable and free from the possibility of' burnout and backfire, by making a partition plate end inside a premixer and by making a part of a slanting part of a flame stabilizer form a flow passage inside the premixer. CONSTITUTION:A partition plate 9 or a swirler 6 is made to end in the middle inside a premixer 4 and a slanting part 6a of a flame stabilizer 6 located on the downstream side thereof is extended from just behind the partition plate 9 or the swirler 5 in the premixer 4 to a sharply expanded part surface 6b of the flame stabilizer 6. According to this constitution, the sectional area of a flow passage in the premixer 4 through which air-fuel premixture AF flows decreases little by little on the downstream side of the partition plate 9 or the swirler 5. Accordingly, unstable combustion due to fire spread to a region just behind the partition plate or the swirler or retention of flame therein is eliminated.
