Patent number: 10451026Abstract: This underwater device is twin-motor underwater floating-type power generation device that is provided with: a device main body that is equipped with a pair of pods that have a turbine, and with a connecting beam that connects these pods together in parallel with each other; a sinker; and tether cables that tether the device main body to the seabed via this sinker. The respective turbines of the pods are each provided with variable pitch turbine blades. This device is also provided with a depth meter that detects deviation in posture in the roll direction that is generated in the pair of pods, and a posture controller that controls the pitch of the variable pitch turbine blades of the respective turbines so as to nullify any deviation in posture in the roll direction that has been generated in the pair of pods and has been detected by the depth meter.Type: GrantFiled: October 6, 2015Date of Patent: October 22, 2019Assignee: IHI CORPORATIONInventors: Norihisa Handa, Shigeki Nagaya, Yoshiyuki Yamane, Akio Ito

Patent number: 9816479Abstract: A pod of an ocean current power generation device which is serving as an underwater floating-type underwater device is provided with a ballast tank and an air storage tank. When discharging water from the ballast tank, by opening a water discharge valve and driving a water discharge pump, water inside the ballast tank is discharged to the outside through a water conduit. When supplying water, by opening a water supply valve while the water pressure outside the pod is greater than the water pressure inside the ballast tank, water is made to flow from the outside of the pod through an aperture portion, and into the ballast tank via the water conduit.Type: GrantFiled: September 30, 2015Date of Patent: November 14, 2017Assignee: IHI CORPORATIONInventors: Norihisa Handa, Shigeki Nagaya, Yoshiyuki Yamane

Patent number: 8984863Abstract: Provided is an ammonia injection device (10) installed at an exhaust gas duct through which an exhaust gas generated in a gas turbine flows, and configured to inject ammonia into the exhaust gas at an upstream side of a denitration catalyst configured to perform denitration processing in a flowing direction of the exhaust gas, the device including a plurality of ammonia injection pipes (11) disposed in parallel each other in a surface which traverses the exhaust gas duct. A plurality of nozzle pipes (12) configured to eject the ammonia from the ammonia injection pipes in an arrangement direction of the plurality of ammonia injection pipes are installed at the ammonia injection pipe in a longitudinal direction of the ammonia injection pipes. Diffuser panels (13) extending toward a downstream side in a flowing direction of the exhaust gas at both sides in a longitudinal direction of the ammonia injection pipes with respect to the nozzle pipes are formed at the nozzle pipes.Type: GrantFiled: November 1, 2011Date of Patent: March 24, 2015Assignee: IHI CorporationInventors: Akinori Yukimura, Masafumi Kawai, Yoshiyuki Yamane

Patent number: 8572965Abstract: 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.Type: GrantFiled: February 6, 2009Date of Patent: November 5, 2013Assignee: IHI CorporationInventors: Hiroyuki Otsuka, Hisakazu Onizuka, Shinsuke Matsuno, Takahisa Nagao, Yoshiyuki Yamane, Atsushi Hirata, Kazuo Miyoshi, Masahiro Nakajima
