English

Subject field(s)
  • Animal Feed (Agric.)
  • Aquaculture
CONT

Extrusion pelleting allows the manufacture of pellets with a greater range of physical and nutritional properties than does steam pelleting. Steam pelleting produces dense pellets that sink quite rapidly. The ingredients are finely ground, mixed, cooked briefly... with steam under pressure to raise the temperature to 70–95°C and the moisture to 15–18%, compressed and forced through a die. The pellets are cut, cooled, dried and may be top-dressed with oil.

DEF

In mining, one who operates steam or electric hoisting machinery used to lower cages(elevators) and skips(large, metal boxlike containers) into a mine and to raise them to the surface from different levels.

OBS

hoist: A power-driven windlass for raising ore, rock, or other material from a mine and for lowering or raising men and material.

CONT

Steam hammers may be of several types, all of which require the use of steam boilers or air compressors.(...) Double-acting hammers use steam or compressed air to raise the striking part and also to impart additional energy during the downstroke. They run at greater speeds than do single-acting hammers.

French

  • Matériel de chantier

CONT

Moutons à double effet: (...) A l'inverse du mouton à simple effet, c'est le piston, alourdi par le bloc de métal, qui constitue la masse frappante. La boîte de distribution envoie automatiquement la vapeur (ou l'air comprimé) tantôt d'un côté, tantôt de l'autre du piston, ce qui a pour effet de la soulever et ensuite de lui donner une impulsion dans sa course descendante. (...) La fréquence élevée de corps pallie dans une certaine mesure l'insuffisance de poids de la masse frappante. (...)

Pressurizer heaters and steam bleed valves control the pressurizer pressure. As pressure rises, the steam bleed valves open to lower it. As pressure falls, the heaters come on to raise it.

Des réchauffeurs du pressuriseur et des vannes de purge de vapeur contrôlent la pression du pressuriseur. À mesure que la pression augmente, les vannes de purge de vapeur s'ouvrent pour la faire baisser. À mesure que la pression diminue, les réchauffeurs interviennent pour la faire monter.

Subject field(s)
  • Heating
  • Nuclear Fission Reactors
  • Compartment - Canadian Nuclear Safety Commission
CONT

The boiler feed pumps(BFP) take suction from the deaerator storage tank and raise the feedwater pressure to between 4 and 7 MPa. The pump discharges the high-pressure feedwater to the high-pressure(HP) feedheaters. The HP feedheaters heat the feedwater to about 170°C. HP feedheater operation and construction are similar to that of the LP feedheaters. Extraction steam from the HP turbine normally supplies the heating medium.

Key term(s)
  • high pressure feedheater

CONT

Cette pompe décharge l'eau d'alimentation sous pression dans les réchauffeurs à haute pression. Ces réchauffeurs poussent la température de l'eau d'alimentation jusqu'à environ 170 °C. Le fonctionnement et la construction du réchauffeur à haute pression sont analogues à ceux du réchauffeur à basse pression. La source normale de chaleur est la vapeur soutirée de la turbine haute-pression.

Record 7 1995-07-26

English

Subject field(s)
  • Heat (Physics)
  • Effects of Heat (Energy Transfer)
CONT

When a pot of cold water is heated on a stove, the temperature rises steadily until the boiling point is reached. Then, counterintuitively, the temperature gets stuck. To unstick the temperature and raise it beyond the boiling point requires strenuous effort, in the form of a large amount of heat that must be supplied to the pot.... The temperature of the water gets stuck because, on the microscopic scale, to change liquid water into steam you must supply energy to rip apart clusters of water molecules. The energy needed to rearrange the molecules does not go into producing faster motion, and so it does not raise the temperature of the water. The temperature thus remains constant until the boiling is complete.

Record 8 1993-03-25

English

Subject field(s)
  • Chemistry
  • Biomass Energy
CONT

spouted bed gasifier.... a single-chamber air-fed gasifier operated on a cyclical basis, to yield a high calorific-value gas essentially uncontaminated by carbon dioxide or nitrogen. Wood chips or wood pellets are fed on top of a bed of hot sand in the reactor, and are then mixed by spouting the bed using steam. Some gasification occurs during this phase, but most takes place during the ensuing "cooking" phase during which the bed is static. When the temperature has fallen to a suitably low value air is admitted to burn the char and raise the temperature of the sand to its original value. Wood is then added to begin a new cycle.

Connect steam condensate(or "return") line of the dishwashing machine to the supply's return pipe system. Care must be taken not to raise the return condensate line above its present level, as this may waterlog the heater.

Steam hammers may be of several types, all of which require the use of steam boilers or air compressors. Single-acting hammers employ steam or compressed air to raise the movable mass which is then tripped and falls by gravity alone. In the United States the movable ram is inside the casing; in Europe the casing is sometimes the movable part.
