  2. Hydrogen-cooled turbo generator - Wikipedia

    en.wikipedia.org/.../Hydrogen-cooled_turbo_generator

    The bearings have to be leak-tight. A hermetic seal, usually a liquid seal, is employed; a turbine oil at pressure higher than the hydrogen inside is typically used. A metal, e.g. brass, ring is pressed by springs onto the generator shaft, the oil is forced under pressure between the ring and the shaft; part of the oil flows into the hydrogen side of the generator, another part to the air side.

  3. Hydrogen safety - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_safety

    The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ...

  4. Inerting system - Wikipedia

    en.wikipedia.org/wiki/Inerting_system

    An inerting system decreases the probability of combustion of flammable materials stored in a confined space. The most common such system is a fuel tank containing a combustible liquid, such as gasoline , diesel fuel , aviation fuel , jet fuel , or rocket propellant .

  5. Inerting (gas) - Wikipedia

    en.wikipedia.org/wiki/Inerting_(gas)

    The inerting systems use an inert gas generator to supply inert make-up gas instead of air. This procedure is often referred to as inerting. Technically, the procedure ensures that the atmosphere in the tank's headspace remains unignitable. The gas mixture in the headspace is not inert per se, it's just unignitable. Because of its content of ...

  6. Hydraulic accumulator - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_accumulator

    One chamber contains the fluid and is connected to the hydraulic line. The other chamber contains an inert gas (typically nitrogen), usually under pressure, that provides the compressive force on the hydraulic fluid. Inert gas is used because oxygen and oil can form an explosive mixture when combined under high pressure. As the volume of the ...

  7. Plasma gasification - Wikipedia

    en.wikipedia.org/wiki/Plasma_gasification

    Pressurized inert gas is ionized passing through the plasma created by the arc. The torch's temperature ranges from 2,000 to 14,000 °C (3,600 to 25,200 °F). [4] The temperature of the plasma reaction determines the structure of the plasma and forming gas. [5]

    Asbestos, a known human carcinogen, can be injurious to consumers if found in talc-containing cosmetic products as there is no established "safe level" threshold for exposure to the substance. If ...

  9. Hydrogen internal combustion engine vehicle - Wikipedia

    en.wikipedia.org/wiki/Hydrogen_internal...

    Emissions from burning hydrogen can be negligible but emissions from producing hydrogen are currently higher than direct combustion of the source. [37] Hydrogen has a wide flammability range (3–70% H 2 in air) in comparison with other fuels. [35] As a result, it can be combusted in an internal combustion engine over a wide range of fuel-air ...
