[Hot water heating systems] Two-pipe systems. For large installations the supply of hot water needs to be kept separate from that water which has been cooled by passing through a convector. To accomplish this one pipe is used to supply the hot water, which then empties into another pipe used for return. This type of system provides the water at as high a temperature as possible. The return may be classified as reverse return or direct return.  5, record 1, English, - two%2Dpipe%20system

In a typical pulp and/or paper mill, about one-half of the process steam is used "indirectly" in tube banks, drying cylinders, and heating jackets. In these applications, the condensate is available for return to the boiler house. A condensate return system involves capital costs for pumps, tanks, traps and piping, but is easily justified because of heat credits and savings in raw water treatment. Where contamination of the condensate is possible(as, for example, with evaporators or black liquor heaters), some method of monitoring the condensate must be employed to prevent return of a fouled stream.  1, record 3, English, - tube%20bank

Dans les papeteries classiques, on consomme la moitié de la vapeur indirectement dans les faisceaux de tubes, les cylindres ou les chemises pour chauffer ou vaporiser la matière de l'autre côté de la paroi. Dans ces applications, on peut renvoyer les condensats dans le générateur. Les circuits de retour des condensats entraînent des frais d'investissement au titre de l'acquisition des pompes, des réservoirs, des séparateurs et des canalisations, mais ces frais sont amplement contrebalancés par les économies réalisées au titre du traitement des eaux. Quand les condensats peuvent être contaminés (par exemple dans le cas des évaporateurs ou des réchauffeurs de liqueur noire), il faut contrôler leur état pour éviter de recirculer un liquide pollué.  1, record 3, French, - faisceau%20de%20tubes

The return piping that carries the condensate accumulation back to the boiler and is installed below the level of the boiler water line is called a wet return. It is completely filled with water and does not carry air or steam. When the system is first filled with water or is cold, the pressure throughout the system is the same, or balances. Therefore, the water is at the same level in the boiler and drip connection as indicated by the boiler water line.  1, record 6, English, - wet%20return
