  • Patent number: 11125166
    Abstract: A control system is configured to control a temperature of a fuel which is supplied to a combustor of a gas turbine via a fuel gas heater, which is configured to heat the fuel of the gas turbine, by adjusting a flow rate of heated water which is supplied to the fuel gas heater. The control system includes a water flow rate adjusting unit configured to adjust the flow rate of the heated water which is supplied to the fuel gas heater based on a difference between a target temperature of the fuel and the temperature of the fuel on an outlet side of the fuel gas heater.

  • Patent number: 10981853
    Abstract: The present invention aims to provide a method for preparing an aldehyde, which can prepare a target aldehyde with high selectivity and can also suppress the production of by-products. The present invention relates to a method for preparing an ?,?-unsaturated aldehyde. The method includes a step of reacting a compound of formula (I) with a compound of formula (II) to provide an ?,?-unsaturated aldehyde of formula (III). An alkali metal hydroxide and an alkanol having 1 to 4 carbon atoms are used in the step. The amount of the alkali metal hydroxide is 8 mol % or more and 12 mol % or less with respect to the compound of formula (I). The total amount of water contained in materials that are used in the reaction is 10 mol % or more and 50 mol % or less with respect to the compound of formula (I).

  • Publication number: 20190010570
    Abstract: The invention provides manufacturing a partially reinforced press formed product with high corrosion resistance and weldability. First and second steel plates having aluminum-based plating films are heated to an austenite range temperature by first and second furnaces, respectively, to transform the bodies of the first and second steel plates into austenite and form Fe—Al alloy layers on the surfaces of the first and second steel plates. Hot press forming is then performed to the first and second steel plates formed with the Fe—Al alloy layers, the first and second steel plates being superposed. The first and second steel plates, which are hot press formed, are then welded.

  • Publication number: 20190009321
    Abstract: The invention provides manufacturing a press formed product with high corrosion resistance and different tensile strengths depending on regions by a small number of processes. The whole of a steel plate having an aluminum-based plating film is heated to an austenite range temperature by a furnace, so that the body of the steel plate is transformed into austenite and a Fe—Al alloy layer is formed on the surface of the steel plate. The steel plate formed with the Fe—Al alloy layer is taken out from the furnace, a first region of the steel plate is heat-retained by a heat resistant and retaining member, and a second region of the steel plate is cooled naturally. When the temperature of the second region becomes lower than a ferrite transformation start temperature, hot press forming is performed to the steel plate to form a press formed product.
