Abstract: A construction component provided with a vibration damper includes a quadrangular frame in a front elevational view including four structural members, and the vibration damper includes: a vibration damping tool provided inside the frame; and four braces radially extending from the vibration damping tool and connected to the frame. The vibration energy deforming the frame is transmitted via the braces to the vibration damping tool to plastically deform the vibration damping tool, thereby absorbing the vibration energy in the vibration damping tool to damp vibration. The construction component further includes a bridging member configured to bridge a gap between two facing members of the four structural members. A part of the bridging member configured to overlap with the vibration damping tool in the front elevational view is defined as an interference avoidance portion in which interference between the part and the vibration damping tool is avoided.

Abstract: According to one embodiment, a carbon dioxide separation recovery system includes an absorption tower that allows carbon dioxide to be absorbed to an absorption liquid, a regeneration tower that regenerates the absorption liquid, a reboiler that heats the absorption liquid of the regeneration tower, using a heating medium, and a measuring device that measures an amount of heat supplied to the absorption liquid from the heating medium. The measuring device includes a cooler that cools the heating medium discharged from the reboiler, and obtains the amount of heat that is supplied to the absorption liquid from the heating medium by subtracting an amount of heat that is retained by the heating medium cooled by the cooler and an amount of heat, which is removed from the heating medium in the cooler, from an amount of heat that is retained by the heating medium supplied to the reboiler.

Abstract: A turbine system and method for power generation has an electric generator, a reformer, a cooler, a fuel compressor, an air compressor, a combustor, a turbine, an evaporator. The reformer reforms fuel containing a mixture of hydrocarbon gas and steam to produce hydrogen and carbon dioxide. To enhance reformation, the reformation is carried out under pressure at 7 ata or less. To aid compression, the cooler cools the reformed fuel before the compressor compresses the reformed fuel. The combustor burns air compressed by the air compressor, which is driven by the turbine, and the reformed fuel received from the fuel compressor to generate hot gas. The turbine receives the hot gas from the combustor and drives the generator to generate electricity. The reformer receives the hot gas discharged from the turbine as a heat source to heat the fuel and chemically reform the fuel.
