  • critical temperature
  • Ultra-high-temperature processing is performed in complex production plants, which perform several stages of food processing and packaging automatically and in succession: Heating Flash cooling Homogenization Aseptic packaging In the heating stage, the treated liquid is first pre-heated to a non-critical temperature (70-80°C for milk), and then quickly heated to the temperature required by the process. (wikipedia.org)
  • The critical temperature is 203 K which would be the highest Tc ever recorded and their research suggests that other hydrogen compounds could superconduct at up to 260 K which would match up with the original research of Ashcroft. (wikipedia.org)
  • Though the exact critical temperature has not yet been determined, weak signs of a Meissner effect at 250K may have appeared in magnetometer tests. (wikipedia.org)
  • molten
  • The yellow color implies a molten metal temperature of approximately 1,000°C, evidently above that which the dark-smoke hydrocarbon fires in the Towers could produce. (ae911truth.org)
  • efficiency
  • proposed HTE systems operate between 100 °C and 850 °C. The efficiency improvement of high-temperature electrolysis is best appreciated by assuming that the electricity used comes from a heat engine, and then considering the amount of heat energy necessary to produce one kg hydrogen (141.86 megajoules), both in the HTE process itself and also in producing the electricity used. (wikipedia.org)
  • 1,400 °C), low-pressure operation, high power density, better electric conversion efficiency than a helium-cooled VHTR operating at similar conditions, passive safety systems, and better retention of fission products in case an accident occurred. (wikipedia.org)
  • The main goals of the design, both from product quality and from efficiency standpoints, are to maintain the high product temperature for the shortest period possible, and to ensure that the temperature is evenly distributed throughout. (wikipedia.org)
  • For higher efficiency, pressurized water or steam is used as the medium for heating the exchangers themselves, accompanied with a regeneration unit which allows reuse of the medium and energy saving. (wikipedia.org)
  • heat
  • SKF High Temperature seals resist heat and thermal expansion to support optimal functionality and long service life. (skf.com)
  • Possible supplies of cheap high-temperature heat for HTE are all nonchemical, including nuclear reactors, concentrating solar thermal collectors, and geothermal sources. (wikipedia.org)
  • Given a cheap, high-temperature heat source, other hydrogen production methods are possible. (wikipedia.org)
  • Thermochemical production might reach higher efficiencies than HTE because no heat engine is required. (wikipedia.org)
  • Heat is absorbed from the surroundings, and the heating value of the produced hydrogen is higher than the electric input. (wikipedia.org)
  • The actual heat flux was 60% less than expected, actual temperatures were much lower than expected, and heat flux on the rear strakes was much higher than expected. (wikipedia.org)
  • Ultra-high temperature processing (UHT), ultra-heat treatment, or ultra-pasteurization is a food processing technology that sterilizes liquid food, chiefly milk, by heating it above 135 °C (275 °F) - the temperature required to kill spores in milk - for 1 to 2 seconds. (wikipedia.org)
  • planes
  • Some directions and planes have a higher density of nodes. (wikipedia.org)
  • These high density planes have an influence on the behavior of the crystal as follows: Optical properties: Refractive index is directly related to density (or periodic density fluctuations). (wikipedia.org)
  • copper
  • In addition, conductivity is up to 20 times higher than that of copper, the material most frequently used for power supply lines. (basf.com)
  • Bednorz encountered a barium-doped compound of lanthanum and copper oxide whose resistance dropped to zero at a temperature around 35 K (−238.2 °C). Their results were soon confirmed by many groups, notably Paul Chu at the University of Houston and Shoji Tanaka at the University of Tokyo. (wikipedia.org)
  • Mechanism
  • High-temperature corrosion is a mechanism of corrosion that takes place in gas turbines, diesel engines, furnaces or other machinery coming in contact with hot gas containing certain contaminants. (wikipedia.org)
  • Voltage
  • A strong electric current under high voltage passes between the two electrodes as an electric arc. (wikipedia.org)
  • steam
  • In 1912, a continuous-flow, direct-heating method of mixing steam with milk at temperatures of 130 to 140 °C was patented. (wikipedia.org)
  • There are two groups of direct systems: Injection-based, where the high-pressure steam is injected into the liquid. (wikipedia.org)
  • Infusion-based, where the liquid is pumped through a nozzle into a chamber with high-pressure steam at a relatively low concentration, providing a large surface contact area. (wikipedia.org)
  • made
  • A High Temperature Filter Unit made by Pall-Werk Schumacher is present and place downstream a circulating fluidized bed gasifier that is involved in the same project as well. (tudelft.nl)
  • Products made from AES are generally used at application temperatures less than 900 °C and in continuously operating equipment and domestic appliances. (wikipedia.org)
  • Products made of alumino silicate wool are generally used at application temperatures of greater than 900°C and in intermittently operating equipment and critical application conditions (see Technical Rules TRGS 619). (wikipedia.org)
  • extreme
  • Ultrahigh-temperature metamorphism (UHT) represents extreme crustal metamorphism with metamorphic temperatures exceeding 900 °C. Granulite-facies rocks metamorphosed at very high temperatures were identified in the early 1980s, although it took another decade for the geoscience community to recognize UHT metamorphism as a common regional phenomenon. (wikipedia.org)
  • below
  • Iron(III) oxide is readily soluble in vanadates between Na2O.6 V2O5 and 6 Na2O.V2O5, at temperatures below 705 °C in amounts up to equal to the mass of the vanadate. (wikipedia.org)
