FUEL FLAT [10 records]

Record 1 2017-04-12

English

Subject field(s)
  • Fuel Cells (Electr.)
DEF

Conductive plate in a fuel cell stack that acts as an anode for one cell and a cathode for the adjacent cell ... The plate usually incorporates flow channels for the fluid feeds and may also contain conduits for heat transfer.

CONT

Because of the configuration of a flat plate cell,..., the interconnect becomes a separator plate with two functions : 1) to provide an electrical series connection between adjacent cells, specifically for flat plate cells, and 2) to provide a gas barrier that separates the fuel and oxidant of adjacent cells.

CONT

The separator plates provide the electrical series connection between cells and physically separate the oxidant flow of one cell from the fuel flow of the adjacent cell.

CONT

While the current SOFC [Solid oxide fuel cell] operates at 1000 °C, this high temperature has limited the materials that can be used for the various cell components (electrolyte, anode, cathode, and interconnect or bipolar plate) to relatively expensive ceramic compositions.

CONT

[In the] SOFC ... [the] electrolyte, anode, cathode and interconnect or bipolar plate [have] relatively expensive ceramic composition.

French

Domaine(s)
  • Piles à combustible (Électricité)
DEF

Plaque utilisée pour brancher des piles à combustible en série.

CONT

[Les] plaques [bipolaires] assurent diverses fonctions dans un assemblage (stack) de piles à combustible : distribution du gaz dans chaque pile de l'assemblage, séparation et distribution des fluides, conductivité électrique et support des piles.

CONT

Le cœur de [la] pile [à membrane électrolyte polymérique (PEMFC)] [...] est mis en série avec le suivant par un interconnecteur qui assure une triple fonction : amener les gaz réactifs au contact des électrodes, transférer le courant électrique d'un cœur de pile à son voisin et évacuer la chaleur produite.

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

No work is allowed at the faces(flat ends) of a running reactor. An end shield provides shutdown shielding only. Thickness of shielding at the reactor face is about one meter. Space is limited by the need to fuel the reactor.

Key term(s)
  • face of a reactor

French

Domaine(s)
  • Réacteurs nucléaires de fission
  • Tiroir - Commission canadienne de sûreté nucléaire
CONT

Le remplacement du combustible épuisé se fait pendant que le réacteur fonctionne. En effet, les grappes de combustible neuves sont poussées dans les tubes de force par la machine télécommandée qui dessert alors une des deux faces du réacteur. Simultanément, les grappes épuisées sont recueillies par la machine desservant l’autre face du réacteur et dirigées vers la piscine de stockage, adjacente au bâtiment du réacteur.

  • Nuclear Fission Reactors
CONT

In the seventies, the CEA, in collaboration with its subsidiaries Sfec and Technicatome, developed a fuel with a low level of enrichment, Caramel. The CEA used complete cores of Caramel in the Isis and Osiris reactors. It recently abandoned use of Caramel in Osiris to the benefit of silicide fuel. Caramel fuel was and, it seems, may still be, used in submarines. Caramel fuel is composed of flat pastilles of uranium oxide enriched to about 7. 5%. Each pastille has almost the shape and size of a true caramel, hence the name.

CONT

In addition to ... plate-type dispersion fuels, the CEA developed and tested the caramel fuel, consisting of sintered UO/sub 2/wafers in Zircaloy-clad plates ...

Subject field(s)
  • Combustion and Fuels (Fireplaces)
  • Nuclear Fission Reactors
CONT

Prior art fuel elements used in nuclear reactors can be divided into two general classes--flat plate fuel elements and cylindrical rod fuel elements. A requirement for plate fuel elements is that the fuel be metallurgically bonded to the cladding. Fuel elements of this type are conventionally brazed in parallel relation between two side plates.

  • Thermal Insulation
DEF

Insulation material installed between the cell mount of an infrared flame detector and the sighting pipe to reduce heat conduction to the cell.

CONT

Electronic Fuel Injection nozzles and fuel rails are subjected to overheating during vehicles operation... Solution. Install a flat rectangular heat shield between the exhaust manifold and the fuel rail. This shield combines a high temperature ceramic heat block with a more cost effective lower temperature resistant fiberglass insulation. An aluminum foil pad is also added to distribute the heat throughout the insulator alleviating any "hot spots. "

Subject field(s)

CONT

Grate fired combustors. Grate-fired systems include both pile burners and spreader-stokers. Pile burners include the old-fashioned Dutch ovens(or Dietrich cells for bagasse and coffee grounds), Wellons cells, Lanb-Cargate wet cell or gasifier burners, and inclined grate systems. Spreader-stokers are distinguished by their feed mechanism, typically a windswept or pneumatic spout or paddle wheel located above the grate and the thin bed of fuel on the grate. The stoker mechanism spreads the fuel more or less uniformly across the grate. Grate fired systems may use flat or sloping grates, with inclined grates being the most severely sloping grate systems. Grates may be stationary or moving. They may be air cooled or water cooled. Ash removal from grates may be accomplished by moving arms, steam or air blowing systems, grate moving, or hand raking. Grate fired units may be refractory lined or waterwall furnaces, depending upon vendor and purpose.
