摘要： Boiler installation with pressurized bed combustion, having a burner, filtration unit with a ceramic filter in a flue arrangement, and a slotted separator, especially a Jalousie Separator, as a primary dust separator arranged between the burner and the filter. A recirculating PFBC with fluidized bed (101) in an outer containment vessel (100), discharges hot, dust-laden combustion gases, via a duct (110) to a separator vessel (1) which contains a primary inclined slot separator (Jalousie) (24), and secondary ceramic candle type filter (3). Hot, dust-free gases are discharged via duct (12) to a gas turbine (120) and thence to a steam raising boiler (130). In a (claimed) embodiment, an ejector device (17; 21) is formed at the light-end dust outlet of the slotted separator, this utilizes the kinetic energy of the separated gas-flow to generate suction through the ceramic filter (3). Fine dust is discharged from hopper (7) and outlet (42); coarse solids removed by the slotted separator, can contain significant amounts of unburned fuel, and are recycled to the PFBC via ducts (41, 40, 111). USE/ADVANTAGE - Pressurized fluidized bed combustion (PFBC) for Power Station use. Compact system of reduced capital cost, with a primary slotted separator protecting the ceramic filter from excessive temperature and high surges in dust load, the latter in turn protects the gas turbine from erosion.

摘要： PROBLEM TO BE SOLVED: To form a grasping structure without using a large-sized device by heating a mat by a heating means attached to a thermally expansible mat, and interposing the mat in an expanded state between the outer surface of a ceramic cylinder and a metallic member having a cylindrical inner surface. SOLUTION: A ceramic cylinder 1 is formed cylindrically by the use of a ceramic fiber, consisting of a compound mainly containing alumina and silica. A thermally expansible mat 2 is used, for example, which is 3 mm thick in the initial stage, and as an electric heater 7, a metal wire 1 mm in diameter consisting of nickel-chromium alloy is used as heating element. A metallic member 3 having a cylindrical inner surface with a structure having a collar at the end. The thermally expansible mat 2 is wound around the upper and lower ends of the ceramic cylinder 1 in one layer, the electric heater 7 is wound thereon at an interval of several mm, and the expansible mat 2 is wound thereon. The processing cost can be reduced without requiring a large-sized heating furnace or deteriorating the seal performance.

摘要： PURPOSE:To improve the distance resolution of temperature distribution measured by an optical fiber distribution type thermometer by taking the process for detecting and correcting incidence of pulse light, and temperature distribution, CONSTITUTION:A controller 26 controls an optical switch 23 and laser light source 24 by outputting control signal, and by taking in the detection signal from a detector 25, measured temperature distribution is calculated, and further, maximum value of measured temperature distribution is corrected. The result of calculation and correction are displayed 27, and if the corrected maximum value is greater than the specified value, warning is displayed 27. With the use of correction factor determined by temperature rising zone width of temperature distribution obtained from rear side scattering light intensity from an optical fiber, the maximum value of temperature distribution is corrected. Thus, the distance resolution of temperature distribution measurement better than that determined by pulse light width is obtained. So, the distance resolution of temperature distribution measured by an optical fiber distribution type thermometer can be improved.

摘要： PURPOSE:To prevent the generation of a backlash between a moving vane and a disk by holding heat-resisting heat-insulating pads among the indentations of the disk divided into two by a surface vertical to a shaft and a moving vane mounting section connected to the indentations. CONSTITUTION:Heat-resisting heat-insulating pads 3, 5 are held among the indentations 28 of disks 25 divided into two by surfaces vertical to a shaft 24 and the mounting sections 2 of moving vanes 26 connected and mounted to the indentations 28. Differences among thermal expansions of the moving vanes 26 and the disks 25 can be absorbed by the pads 3, 5. Accordingly, the generation of backlashes among the moving vanes 26 and the disks 25 can be prevented even when a turbo-machine is operated under high centrifugal force at a high temperature.
摘要翻译：目的：为了防止在移动叶片和盘之间产生间隙，通过在垂直于轴的表面上分隔成两个的盘的凹陷之间保持耐热隔热垫，以及连接到轴的移动叶片安装部压痕。构成：将耐热绝热垫3,5保持在与轴24垂直的两个分开的盘25的凹口28和连接并安装到凹痕28的移动叶片26的安装部分2之间。差异移动叶片26和盘25的热膨胀可以被垫片3,5吸收。因此，即使当涡轮机在高离心力下操作时，也可以防止活动叶片26和盘25之间产生间隙强力在高温下。
