DOWNSTREAM POWER [13 records]

Record 1 2017-02-14

English

Subject field(s)
  • Hydroelectric Power Stations
  • Hydrology and Hydrography
DEF

A hydroelectric power plant that uses water flow as it comes in the river, with little or no storage to allow for modifications in demand of water flow.

CONT

Run-of-river power stations use the natural flow of river water to drive turbines. Although the head of water between the upstream and downstream sides is modest compared to storage power stations, the volume of water available is usually greater. Run-of-river power stations operate continuously. They meet basic electricity needs by supplying the steady underlying demand. The amount of electricity produced depends on the river's flow; they are generally more productive in summer than in winter.

CONT

Between 1998 and 1999, a unique and innovative hydroelectric project was implemented through a partnership with a First Nations community. A run-of-the river hydroelectric plant, which uses the natural course of the river rather than requiring the construction of dams, was installed in the community of Deer Lake.

Key term(s)
  • run of the river hydroelectric power plant

French

Domaine(s)
  • Centrales hydro-électriques
  • Hydrologie et hydrographie
DEF

Usine construite sur un cours d'eau dont le débit n'est pas réglé.

CONT

Entre 1998 et 1999, l'entreprise a mis en œuvre un projet hydroélectrique unique et innovateur en partenariat avec une collectivité des Premières nations. Elle a construit, dans la collectivité de Deer Lake, une centrale hydroélectrique au fil de l'eau, qui utilise le tracé naturel de la rivière plutôt que de recourir à la construction de barrages.

OBS

Peu d'eau et une chute importante pour la centrale à accumulation, beaucoup d'eau et une faible chute pour les ouvrages au fil de l'eau. Telles peuvent être résumées les principales caractéristiques des deux plus importants types de production d'énergie hydroélectrique. Les ouvrages au fil de l'eau. Les centrales sont situées sur une rivière et n'ont pas de réservoir. Elles s'adaptent donc au débit naturel du cours d'eau. Les ouvrages fournissent une énergie «en ruban», c'est-à-dire une énergie continue mais dépendante du débit. Les ouvrages à accumulation. Ces centrales utilisent l'eau stockée par les barrages dans les lacs naturels ou artificiels. La chute d'eau, totalement contrôlée, actionne les turbines pour produire de l'électricité. En l'espace de quelques minutes, la centrale peut ainsi produire sa pleine puissance.

OBS

hydroélectrique; hydro-électrique : La graphie sans le trait d'union est aujourd'hui préférée.

OBS

hydroélectrique : Cette graphie, puisée des Rectifications de l'orthographe recommandées par le Conseil supérieur de la langue française, est attestée dans le Petit Robert (2004).

Spanish

Campo(s) temático(s)
  • Centrales hidroeléctricas
  • Hidrología e hidrografía
DEF

Central hidroeléctrica que no posee embalse regulador.

OBS

No se dispone de ninguna reserva: el embalse de la central solamente tiene por objeto aumentar en lo posible la altura de la caída (hasta 10 m) y la central puede ser inutilizable durante el estiaje, mientras que, durante las avenidas se pierde el exceso de agua que no puede pasar por las turbinas.

The highly-integrated complex makes ExxonMobil the single largest investor on Jurong Island and Singapore's biggest foreign investor. It is now supplying petrochemical products to the marketplace. Singapore Chemical Complex has four plants designed to deliver a wide range of petrochemical products to its customers. Its centrepiece is an 800, 000-ton-per-year steam cracker, which produces ethylene, propylene and other products for several downstream chemical plants in and around Singapore. Other features of the facility includes a polyethylene plant, the largest single reactor of its type in the world, a polypropylene plant, an oxo-alcohol plant and a cogeneration unit which provides power to both the refinery and the chemical plant.

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.

Power combustion furnaces utilize a combustion blower which may be located either upstream or downstream from the heat exchangers. If the blower is located upstream blowing the combustion air into the heat exchangers, the system is called a forced draft system. If the blower is downstream, the arrangement is called an induced draft system.
