  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 ...

    en.wikipedia.org/wiki/Coefficient_of_performance

    The coefficient of performance or COP (sometimes CP or CoP) of a heat pump, refrigerator or air conditioning system is a ratio of useful heating or cooling provided to work (energy) required.

  5. 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.

  6. Superheated water - Wikipedia

    en.wikipedia.org/wiki/Superheated_water

    Water is a polar molecule, where the centers of positive and negative charge are separated; so molecules will align with an electric field.The extensive hydrogen bonded network in water tends to oppose this alignment, and the degree of alignment is measured by the relative permittivity.

    Figure 1: Rangekeeper Coordinate System. The coordinate system has the target as its origin. The y axis value range to the target. US Navy rangekeepers during World War II used a moving coordinate system based on the line of sight (LOS) between the ship firing its gun (known as the "own ship") and the target (known as the "target").
