  2. Superheating - Wikipedia

    en.wikipedia.org/wiki/Superheating

    Superheating can occur when an undisturbed container of water is heated in a microwave oven.At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm.

  3. Superheated steam - Wikipedia

    en.wikipedia.org/wiki/Superheated_steam

    Superheated steam was widely used in main line steam locomotives. Saturated steam has three main disadvantages in a steam engine: it contains small droplets of water which have to be periodically drained from the cylinders; being precisely at the boiling point of water for the boiler pressure in use, it inevitably condenses to some extent in the steam pipes and cylinders outside the boiler ...

  4. Steam explosion - Wikipedia

    en.wikipedia.org/wiki/Steam_explosion

    Littoral explosion at Waikupanaha ocean entry at the big island of Hawaii was caused by the lava entering the ocean. A steam explosion is an explosion caused by violent boiling or flashing of water or ice into steam, occurring when water or ice is either superheated, rapidly heated by fine hot debris produced within it, or heated by the interaction of molten metals (as in a fuel–coolant ...

  5. Superheated water - Wikipedia

    en.wikipedia.org/wiki/Superheated_water

    Pressure cookers produce superheated water, which cooks the food more rapidly than boiling water.. Superheated water is liquid water under pressure at temperatures between the usual boiling point, 100 °C (212 °F) and the critical temperature, 374 °C (705 °F).

  6. Superheater - Wikipedia

    en.wikipedia.org/wiki/Superheater

    A radiant superheater is placed directly in the radiant zone of the combustion chamber near the water wall so as to absorb heat by radiation. A convection superheater is located in the convective zone of the furnace, in the path of the hot flue gases, usually ahead of an economizer.

  7. Thermal expansion valve - Wikipedia

    en.wikipedia.org/wiki/Thermal_expansion_valve

    The superheat is the excess temperature of the vapor above its boiling point at the evaporating pressure. No superheat indicates that the refrigerant is not being fully vaporized within the evaporator and liquid may end up recirculated to the compressor which is inefficient and can cause damage.

  8. Gurney equations - Wikipedia

    en.wikipedia.org/wiki/Gurney_equations

    Gurney developed a simple and convenient formula based on the conservation laws of momentum and energy that model how energy was distributed between the metal shell and the detonation gases that is remarkably accurate in many cases.
