TUBE HEATER [14 records]

Record 1 2017-06-12

English

Subject field(s)
  • Electrical Circuits and Circuit Breakers
  • Air Conditioning and Heating
CONT

Air flow switch-A pressure differential switch is used to prevent a heater from operating if there is no airflow across the heating elements. The switch is provided with a pitot tube to be installed into the duct, which makes it sensitive to velocity pressure as well as to static pressure. In applications where there is not enough pressure to activate a differential pressure switch, an electronic air flow sensor should be specified.

Key term(s)
  • switch for air flow

  • Conditionnement de l'air et chauffage
CONT

Interrupteur de débit d'air - Un interrupteur à différentiel de pression sert à empêcher le fonctionnement du serpentin quand le débit d'air est interrompu au travers des éléments. Cet interrupteur est fourni avec un tube de Pitot à installer dans le conduit, ce qui le rend sensible à la pression de vélocité et à la pression statique. Pour les installations où la pression n'est pas suffisante pour activer un interrupteur à différentiel de pression, il faudrait spécifier un détecteur électronique de débit d'air.

Subject field(s)
  • Vacuum Tubes (Electronics)
CONT

Hot cathodes may be either directly heated, where the filament itself is the source of electrons, or indirectly heated, where the filament is electrically insulated from the cathode; this configuration minimizes the introduction of hum when the filament is energized with alternating current. The filament is most often made of tungsten. With indirectly heated cathodes, the filament is usually called the heater instead. The cathode for indirect heating is usually realized as a nickel tube which surrounds the heater.

OBS

indirectly heated cathode: term officially approved by the Electronics and Telecommunications Terminology Committee.

Test(pressure decay test) the combustion tube of the heater and conduct an operational test of the combustion air pressure switch...

OBS

Pressure decay has been the most widely used method of leak testing in manufacturing production lines for decades. The process is uncomplicated, inexpensive and easily automated. Air is injected into a test object, and any decrease in air pressure over time signifies a leak. However, the pressure decay method has limited sensitivity and is unable to determine the location of leaks.

Aseptic juice processing with pulp.... Raw product from the balance tank is transported by a booster pump through the raw regenerator section where it is pre-heated by sterile product form the sterile regenerator. The product then flows to the timing pump, which controls the product flow rate of the system. Pre-heated raw product enters the heater section from the timing pump and is heated to the sterilizing temperature before entering the holding tube. Processed product from the holding tube enters the sterile regenerator section where it is pre-cooled by incoming product form the raw regenerator. Processed product is then cooled to filling temperature and flows through a set of divert valves to a customer supplied filler or back to the balance tank.

CONT

The new 60-megawatt segmented arc heater, known as H3, significantly improves AEDC' s [Arnold Engineering Development Center] present arc capabilities... Arc heaters such as H3 produce the high pressures and heat fluxes required for testing thermal protection materials used for nose tips and heat shields. Arc heater tests provide information to manufacturers about the probable condition a space vehicle component would experience following re-entry into Earth's atmosphere. An arc heater is basically a large tube that high-pressure air runs through. The air is heated by discharging tens of megawatts of power using an electric arc similar to a lightning bolt. At the nozzle, or downstream end of the heater, test personnel install models or materials and subject them to simulated high pressure and temperature conditions generated by the bolt. Temperatures range from 5, 000 to 15, 000 degrees Fahrenheit, requiring each component to be water-cooled.

CONT

Automobile tires after assembly on a drum are shaped to size and then vulcanized in engraved steel molds. The molds are stacked one on top of the other in vertical pot heaters, and steam is admitted to the closed heater. An air bag resembling an inner tube is inserted in the unvulcanized casing. Air, steam, hot water, or combinations of these are introduced into the air bag by flexible connections of copper tubing, expanding the tire carcass and causing the rubber to flow into the design of the mold.

The starter air shutoff valve incorporates a pneumatic heater tube which taps into the pneumatic duct system upstream of the butterfly valve. This provides a continuous flow of hot air on the valve body and switcher mechanism to prevent freezing or to thaw a frozen valve, when APU/engine operates. The pneumatic heater tube is removable for cleaning and to facilitate unblocking.
