  • Publication number: 20210215052
    Abstract: A turbine impeller includes: a base material which contains aluminum as a main element; and an anti-erosion coating which covers a surface of the base material. Accordingly, since liquid droplets hit the anti-erosion coating before the base material even when the liquid droplets flow into the rotating turbine impeller, the damage to the base material due to erosion is suppressed.

  • Patent number: 8572965
    Abstract: A chimney has a lower portion substantially in the shape of a pyramid and an upper portion forming a cylindrical portion that extends with a predetermined dimension upwardly and is provided in a ceiling portion of a building of a coil yard that is used for temporary storage of the hot-rolled coil which is an intermediate iron and steel product acting as a high-temperature heat radiator that is manufactured using the hot-rolling equipment of an iron and steel mill. A power generating turbine is provided at a predetermined position in the cylindrical portion. An intake duct is provided on a lower end portion of the side walls of the building. Hot-rolled coils that are in a high-temperature condition after manufacture are successively imported into the coil yard and accumulated and stored until transfer to a subsequent processing step. An ascending airflow is generated by sequential heating of air introduced into the building from the intake duct using heat retained in the hot-rolled coils.

  • Publication number: 20120097151
    Abstract: In this steam supply apparatus, a steam inlet (20a) of a steam injector (20) is connected to a steam outlet (19a) of a high-pressure steam-generating boiler (19). A solar heat-collector (22) is connected to an inlet port (20b) of the steam injector (20), and steam-utilizing equipment (25) is connected to a discharging port (20c). The steam injector (20) is driven by high-pressure and high-temperature steam (27) generated by the high-pressure steam-generating boiler (19), and pressure of the inlet port (20b) is decreased. In the inner portion of the solar heat-collector (22) which is decompressed according to a decrease in pressure of the inlet port (20b), water with a temperature increased by irradiation of the sunlight (24) is boiled and evaporated at less than 100° C., and low-pressure and low-temperature steam (28) is generated.

  • Publication number: 20100012835
    Abstract: The inside of the collision cell 20 placed in the analysis chamber 10 which is vacuum-evacuated is partitioned into an anterior chamber 23 and a posterior chamber 24 by the partition wall 21 with a communicating aperture 22. The former is used as a dissociation area A1 and the latter as a convergence area A2. Electrodes 27 and 28 for forming a radio-frequency electric field are placed in the chambers 23 and 24, respectively. When a CID gas is supplied into the anterior chamber 23, the CID gas is dispersed inside the anterior chamber 23 and flows into the analysis chamber 10 via the posterior chamber 24. Consequently, the gas pressure in the posterior chamber becomes higher than the gas pressure in the analysis chamber 10, and the gas pressure in the anterior chamber 23 becomes higher than the gas pressure in the posterior chamber 24.
