A boiler plant includes a carbon dioxide capture system. The carbon dioxide capture system has an absorbing-liquid regeneration device and an absorber. The absorbing-liquid regeneration device includes a regenerator, a first circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, and a second circulation line in which the absorbing liquid is taken out from the regenerator and is returned to the regenerator, a heat exchanger, a heater, and a switcher. The heat exchanger heats the absorbing liquid by exchanging heat between the absorbing liquid flowing through the first circulation line and steam from the boiler. The heater heats the absorbing liquid flowing in the second circulation line. The switcher switches between a first heating state, in which the absorbing liquid flows in the first circulation line, and a second heating state, in which the absorbing liquid flows in the second circulation line.

The bogie includes: running wheels to be rolled on a road surface of guideway; an axle which is installed on a lower part of a body of a guideway vehicle and to which the running wheels are attached; a chassis supporting the axle; a guide device which is configured to be guided by the guideway and is installed on the chassis so as to be capable of turning around a turning axis extending in a vertical direction; a steering device which is configured to steer the running wheels in response to a turning movement of the guide device when the guide device is turned along a curved section of the guideway; and a tilting device which is connected to the guide device and which is configured to generate a tilting force of directing one side of the body located at an outside of the curved section upward with respect to the other side of the body located at an inside of the curved section in response to the turning movement of the guide device.

A vehicle vibration control system includes: a buffer mechanism that is disposed between a wheel and a vehicle body and capable of adjusting buffer performance as a function of reducing vibration input to the vehicle body from the wheel; a weight detection unit that detects the weight of the vehicle body; a traveling position detection unit that detects the traveling position of the vehicle body; and a control device that controls the buffer performance of the buffer mechanism. The control device acquires a driving pattern in which the traveling position of the vehicle body and the buffer performance were set, on the basis of the weight of the vehicle body, and controls the buffer performance of the buffer mechanism on the basis of the acquired driving pattern and a result detected in the traveling position detection unit.

A gas turbine plant includes a gas turbine, an exhaust line, an exhaust heat recovery boiler that generates steam due to heat of exhaust gas and guides the exhaust gas to the exhaust line, a carbon dioxide recovery device that recovers carbon dioxide contained in the exhaust gas, a heat exchanger that cools the exhaust gas to a temperature set in advance, and a circulation line that branches from a position between the carbon dioxide recovery device and the heat exchanger and is connected to an inlet of the gas turbine. The carbon dioxide recovery device has an absorption tower that absorbs carbon dioxide contained in the exhaust gas by causing the exhaust gas at the set temperature and an absorption liquid to come into contact with each other. The heat exchanger is formed of a material having higher corrosion resistance than a material forming the exhaust heat recovery boiler.

An acceleration monitoring device that comprises: an acquisition unit that acquires measured acceleration waveforms, being acceleration waveforms measured by a vehicle that is traveling a trajectory; a storage unit that stores a reference acceleration waveform, being an acceleration waveform that serves as a reference for measured acceleration waveforms for a predetermined area of interest that is part of the trajectory; and a monitoring unit that monitors the acceleration values for non-linear expanded/contracted and measured acceleration waveforms, being acceleration waveforms made to correspond to the reference acceleration waveform by non-linearly expanding and contracting the time axis for measured acceleration waveforms.

An analysis system includes: a collection unit configured to collect soluble iron contained in a sample; a reaction unit configured to produce a reaction solution; a detection unit configured to detect an absorbance of the reaction solution; and a supply control unit configured to supply the soluble iron collected in the collection unit and a reagent to the reaction unit.

A gas purification device includes: a converter packed with a catalyst for hydrolyzing both carbonyl sulfide and hydrogen cyanide; an upstream heat exchanger for heat exchange between a gas to be introduced into the converter and a cooling fluid for cooling the gas; a reaction-temperature estimation member for estimating a reaction temperature inside the converter; and a flow-rate adjustment member for adjusting a flow rate of the cooling fluid flowing into the upstream heat exchanger based on an estimated value of the reaction-temperature estimation member to control the reaction temperature.

This verification processing device is provided with: an inspection unit that performs model inspection on an inspection target model including a plurality of elements; a selection unit that selects at least one of the plurality of elements included in a counterexample outputted as a result of the model inspection; and an exclusion history generation unit that generates exclusion history information indicating an exclusion frequency for each of the plurality of elements. The inspection unit further performs another model inspection on the inspection target model obtained by excluding the selected element. When another counterexample has been outputted as a result of another model inspection, the exclusion history generation unit increases the exclusion frequency of the selected element and updates the exclusion history information. The selection unit selects an element that is high in the exclusion frequency, on the basis of the exclusion history information.

This positioning configuration design device includes a positioning configuration setting unit that excludes facilities which are likely to be able to be excluded from facilities respectively positioned at a plurality of locations and sets a positioning configuration of the facilities; a feasibility confirmation unit that judges whether predetermined conditions are feasible or not in the set positioning configuration of the facilities; an exclusion candidate list updating unit that registers, in an exclusion candidate list, information of the facilities excluded in the positioning configuration in which the conditions are feasible, a non-excludable list updating unit that registers, in a non-excludable list, information of the facilities excluded in the positioning configuration in which the conditions are not feasible; and a control unit that repeatedly executes confirmation processing including setting of the positioning configuration and judgment of feasibility of the conditions while incrementing the number of facilities to be excluded one at a time until a positioning configuration in which the conditions are feasible and no further facilities are able to be excluded is able to be calculated.

A CO 2 recovery unit includes a CO 2 absorber that brings a gas having a low CO 2 concentration into countercurrent contact with a CO 2 absorbent to remove CO 2 from the gas. The CO 2 recovery unit further includes a first absorbent circulation line that supplies a CO 2 absorbent from a first CO 2 absorption section as a first circulation solution to an upper side of a first CO 2 absorption section; a second absorbent circulation line that supplies a CO 2 absorbent from a second CO 2 absorption section as a second circulation solution to an upper side of a second CO 2 absorption section; and an absorbent discharge line that discharges a part of the first circulation solution from the first absorbent circulation line and supply the part of the first circulation solution as a discharged solution to the second absorbent circulation section.
