air heater [3 records]

Record 1 2007-10-30

English

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
  • Steam-Powered Machines and Condensers
  • Thermal Power Stations
DEF

A component of a steam-generating unit that absorbs heat from the products of combustion after they have passed through the steam-generating and superheating sections.

CONT

Heat recovered from the gas is recycled to the furnace by the combustion air and is absorbed in the steam-generating unit, with a resultant gain in overall thermal efficiency ... Air heaters frequently are used in conjunction with economizers, because the temperature of the inlet air is less than that of the feedwater to the economizer ...

CONT

Air heaters are usually classed as recuperative or regenerative types. Both types depend upon convection transfer of heat from the gas stream to a metal or other solid surface and upon convection transfer of heat from this surface to the air.

PHR

Regenerative-type, rotary regenerative, plate-type, tubular air heater.

DEF

[...] récupérateur de chaleur, utilisé concurremment avec l'économiseur pour pousser au maximum le refroidissement des fumées; il est placé après l'économiseur, sur le parcours de celles-ci, parce que la température de l'eau d'alimentation, à l'entrée de l'économiseur, est supérieure à celle de l'air frais.

CONT

Les centrales thermiques conventionnelles posent des problèmes d'épuration d'effluents liquides divers [...], tels que les éluats de régénération des échangeurs d'ions, les effluents alcalins de lavage des réchauffeurs d'air [...]

Record 2 2007-07-23

English

Subject field(s)
  • Ovens, Furnaces and Boilers (Heating)
DEF

A self-contained heating appliance, which may or may not include an integral fan for circulating air, which may be of the floor-mounted or suspended type, intended for the heating of the space in which it is installed.

CONT

... unit heaters in present use can usually be classified according to one or more methods: 1. By Heating Medium ... a) steam, b) hot water, c) gas indirect-fired, d) oil indirect-fired, e) electric. 2. By Type of Fan ... a) propeller, b) centrifugal, and c) remote air mover ... 3. By Arrangement of Elements ... a) the draw-through type, in which the fan draws air through and b) the blow-through type, in which the fan blows air through the heating element. Indirect-fired unit heaters are always of the blow-through type.

CONT

A unit heater [means] a forced convection heating device of two types: 1) an assembly of encased heating surface with fan and motor (or turbine) and for connection to a source of steam or hot water; 2) an assembly of the above plus a fuel burner so that the device is for connection to a source of oil or gas (or supplied with coal) and not to steam or water lines.

French

Domaine(s)
  • Fours et chaudières (Chauffage)
DEF

Appareil autonome de chauffage comprenant un ventilateur et un élément chauffant, pulsant directement l'air chaud dans le local à chauffer.

CONT

L'aérotherme peut être à chauffage direct, avec le mazout ou le gaz comme source de chaleur, ou à chauffage indirect; il comporte alors un corps de chauffe en tube de cuivre ou en tube d'acier avec ailettes. Les aérothermes comprennent un groupe moto-ventilateur qui peut être hélicoïde [...] ou centrifuge [...] L'aérotherme comporte de plus une carcasse sur laquelle sont branchées une ou plusieurs bouches de chauffage. À sa partie basse est prévue la reprise d'air. Très souvent, une autre tubulure est prévue pour l'alimentation en air neuf [...] Ces appareils, prévus pour le chauffage des grandes surfaces [ateliers, entrepôts], peuvent être suspendus, muraux ou sur socles.

Spanish
