In refrigeration
superheat is the amount of heat added to the refrigerant after it has changed from liquid state into a vapor state.
Kaynak: SuperheatBut a container of liquid with only microscopic bubbles can
superheat dramatically. Occurrence via microwave: Superheating can occur when an
Kaynak: SuperheatingBumping is a phenomenon in chemistry where liquids boil ed in a test tube will
superheat and, upon nucleation , rapid boiling will expel
Kaynak: Bumping (chemistry)The mold constant B depends on the properties of the metal, such as density, heat capacity , heat of fusion and
superheat, and the mold,
Kaynak: Chvorinov's ruleMost designs are thermal rocket s where the energy is provided by the beam, and is used to
superheat propellant that then provides
Kaynak: Beam-powered propulsionBeta uses a nuclear reactor to
superheat either air (when flying in the lower, denser, part of the atmosphere) or its own internal supply
Kaynak: Prelude to SpaceIt was a ramjet that used nuclear fission to
superheat incoming air instead of chemical fuel. Project Pluto produced two working
Kaynak: Supersonic Low Altitude MissileIt was built with a low-degree
superheat domeless boiler and still carries a domeless boiler. Fifteen Guinea Special: The locomotive was one
Kaynak: LMS Stanier Class 5 4-6-0 5110They had a high degree of
superheat, and a firebox that was so wide, it had two firehole doors. They were retired in 1962; and one
Kaynak: SNCB Type 1The Rankine cycle shown here prevents the vapor ending up in the
superheat region after the expansion in the turbine, Van_Wyllen | 1 | a
Kaynak: Rankine cycleThe copper steam pipe exits from the bottom of the boiler inside the firebox, thus getting a very small degree of
superheat.
Kaynak: CyldonHowever the low flow rate made a high
superheat necessary to prevent solidification in the nozzle. The next generation melting procedures
Kaynak: Spray formingwith domeless boilers with straight throatplates and a low degree of
superheat (14 elements in two rows), the boilers of the remaining 13
Kaynak: LMS Stanier Class 5 4-6-0Johnson boiler: a later form of Johnson boiler operating at lower pressure (450psi rather than 850psi), but still a high
superheat temperature
Kaynak: List of boiler types, by manufacturerInitial
superheat performance was disappointing.
Superheat at full power was limited deliberately to 100 | °F so as to avoid reliability
