  • METHOD FOR CONTROLLING HYDROGEN GENERATION SYSTEM, AND HYDROGEN GENERATION SYSTEM
    Publication number: 20220316075
    Abstract: A method for controlling a hydrogen generation system includes controlling the potentials of an electrode for oxygen generation and an electrode for hydrogen generation included in an electrolyzer so that the potential change is smaller in the electrode for oxygen generation or the electrode for hydrogen generation having a larger deterioration rate than in the electrode having a smaller deterioration rate.

  • METHOD FOR MEASURING AMOUNT OF PARTICULATE MATTER ACCUMULATED IN AN EXHAUST GAS PURIFICATION FILTER
    Publication number: 20140196519
    Abstract: A measurement method capable of accurately evaluating the trapped amount of particulate matter (PM) accumulated in a diesel particulate filter (DPF) is provided. The method for measuring the amount of accumulated particulate matter comprises propagating ultrasonic waves generated by a transmitter 3 provided directly to the DPF or outside a container and insulation material 6 having a property that propagates ultrasonic waves, measuring the amount of PM accumulated in the DPF 2 using a receiver 4, the DPF being composed of porous ceramic and disposed at an intermediate point in the exhaust pipe 1 of a diesel engine, and determining the amount of accumulated PM on the basis of the results.

  • Atmospheric pressure combustion turbine system
    Patent number: 7204077
    Abstract: Techniques suitable for recovering energy from a high-temperature gas of an ordinary pressure are provided. A turbomachine has a turbine 16 and compressors 20 and 24. A combustor 12 is disposed at a stage above the turbine 16. A power generating system generates power by passing a working fluid for the turbomachine through the combustor 12, the turbine 16 and the compressors 20 and 24 in that order.
