HOT WATER PUMP [21 records]

Record 1 2017-04-20

English

Subject field(s)
  • Nuclear Plant Safety
CONT

An ex-vessel steam explosion may occur if the primary system is breached by hot debris. Debris in the reactor outlet piping may fail the piping and fall onto the pump room floor or debris on the reactor vessel bottom may be blocked from flowing into the outlet piping if it freezes in the effluent piping nozzle muff structure. If this occurs, the debris will heat up on the reactor vessel bottom and eventually fail the bottom shield. The likely mode of failure of the bottom shield is collapse of the shield as a whole. If it collapses, the entire shield, as well as the molten debris, will fall into the pin room below the reactor vessel. The debris will then flow across the floor into the pump room. In either event, a large portion of the reactor fuel inventory will be deposited on the pump room floor. The pump room floor will be covered with water in many scenarios. A steam explosion may result when the debris enters this water.

CONT

La condition nécessaire à une explosion vapeur est le simple contact entre les deux fluides, mais les situations les plus énergétiques sont celles où les deux fluides sont mélangés avant que ne se déclenche la fragmentation. Dans les réacteurs à eau pressurisée de tels mélanges pourraient se former après la fusion du cœur lors de la relocalisation du corium en fond de cuve (explosion en cuve) et/ou éventuellement lors de la percée de la cuve et la chute du corium dans le puits de cuve (explosion hors cuve).

CONT

The bitumen extraction processes initially used by GCOS [Great Canadian Oil Sands] and Syncrude were based on the Hot Water Extraction Method... Oil sands ore is moved from the base mine dump pocket by conveyor and enters large rotating tumblers where the ore is slurried... to condition it for bitumen separation. The aerated slurry from the tumblers discharges into vibrating screens where large materials... are rejected. The slurry is diluted in pump boxes and pumped to the Primary Separation Vessels(PSV), where bitumen rises to the surface as a froth and is skimmed off, while the sand settles to the bottom.

OBS

primary separation vessel: term usually used in the plural.

Subject field(s)
  • Heating
DEF

A heating system for a building in which the heat-conveying medium is hot water, and the heat-emitting means are radiators, convectors, or panel coils.

CONT

Hydronic heating maintains comfort in the home by circulating hot water to the secondary heat exchanger. This system basically consists of a boiler, a pump, a secondary heat exchanger, and a series of piping.

OBS

Low-temperature water heating system. Some authors use indifferently "hot water system" or "low-temperature water heating system" to designate a heating system having hot water at a temperature lower than 250 °F.

OBS

hot(-)water heating; hydronic heating. Some authors often use the term "heating" to designate a "heating system". The term "System" is then omitted.

OBS

Technically, a "hydronic system" may be either a "hot water system" or a "steam system", as confirmed in the source AMERI. However, many sources define a "hydronic system" as a "hot water system".

French

Domaine(s)
  • Chauffage
CONT

Le principe de base du système à eau chaude est bien connu: l'eau contenue dans une chaudière ("fournaise") est d'abord chauffée par un appareil fonctionnant au mazout, au gaz, ou à l'électricité; circulant ensuite dans des canalisations, elle alimente des radiateurs ou des convecteurs, installés dans chacune des pièces de la maison. Au bout de sa course, l'eau revient à l'appareil pour être chauffée de nouveau avant d'entreprendre un autre cycle, et ainsi de suite.

Subject field(s)
  • Centrifugal Pumps
  • Heating
CONT

Circulating pump. The hot water is circulated from the boiler through the pipes and back to the boiler by a pump. The pump provides fast distribution of hot water through the system, thus delivering heat as quickly as possible. The circulating pump size is based on the delivery of water required, in gpm, and the amount of friction head allowed. Circulating pumps are not used on gravity systems.

CONT

... hot water systems now use a circulating pump. This pump increases the water flow, carries more heat per unit of time to the room heat transfer units, and permits smaller furnaces.

French

Domaine(s)
  • Pompes centrifuges
  • Chauffage
CONT

Avec un système fermé, [...] Par l'utilisation d'une pompe de circulation, on peut obtenir une pression plus grande que dans un système par gravité et un mouvement plus rapide de l'eau chaude. Ceci permet une perte de chaleur moindre à travers les radiateurs et les tuyaux de transmission, de sorte que la quantité de chaleur émise en B.T.U. s'en trouve augmentée.

CONT

Les pompes de circulation peuvent être construites de deux façons: il y a d'abord les pompes à hélice (propeller); en second lieu, on trouve des pompes centrifuges. Toutes sont agencées de manière que la circulation puisse aussi se faire à travers la pompe lorsqu'elle arrête de fonctionner.

CONT

... another possible way of creating permeability in hot dry rocks is «impact fracturing». This method... [may be described in its principle. ] A bore, cased except near the lower extremity, is surmounted by a hydraulic accumulator, filled with water and pressurized by means of a pump until the accumulator weight is lifted. The lifting pressure should be perhaps about 90% of the estimated hydro-fracturing pressure. A dynamic blow would then be struck upon the top of the water column by means of some device resembling a pile-driver, so that shock waves would travel to the base of the bore and be reflected up and down at attenuating intensity. Very high instantaneous pressures would be generated which would fracture the rock, and it is expected that the steepness of the pressure rise would be such as to resemble explosive action, so that the «star» formation... would be produced.

Exhausting includes the removal of air from the filled can and the establishment of conditions whereby the finished canned product will show a substantial degree of vacuum. This can be done by heating the filled can in steam or hot water for several minutes so that the air is driven out and the temperature of the contents is raised considerably. It can also be accomplished by a vacuum closing machine where the air is sucked out by a pump and the lid is sealed on while the suction is being maintained.

CONT

Return Flow Mechanical Atomizing Oil Burners. This [commercial-industrial oil] burner is a modification of a mechanical atomizing burner; atomization is accomplished by oil pressure alone.... The burner was developed for use in large installations such as on shipboard and in electric generating stations.... It is also used for firing large hot water boilers compressed air is too expensive for atomizing oil in large burners.... Wide range is accomplished by use of a return-flow nozzle which has a swirl chamber just ahead of the orifice or sprayer plate. Good atomization is attained by maintaining a high rate of oil flow and high pressure drop through the swirl chamber. The excess oil above the load demand is returned from the swirl chamber to the oil storage tank or to the oil pump suction. Control of burning rate is accomplished by varying the oil pressure in both the oil inlet and the oil return lines.

OBS

This is a register-type burner similar to the mechanical atomizing burners.

When the boiler is used for both space heating and the supply of domestic hot water, the room thermostat controls the burner and the pump through a relay. The high-limit control operates in the same way for both systems. When space heating is not required, the room thermostat shuts off the pump and the burner. A low-limit control in the boiler turns the burner on and off to maintain the temperature of water in the boiler for domestic hot-water use.
