As the boiler heats water, a substantial amount of condensation occurs. Instead of letting this valuable moisture simply evaporate, a condensate receiver, also called a condensate tank, captures it and sends it back to the boiler room so it can be reused.  4, record 1, English, - condensate%20tank

Compression causes the moisture in the air to form droplets of water, or condensate.... This causes a large part of the condensate to precipitate on the walls of the receiver. The condensate collects on the floor of the receiver and is removed by a suitable condensate separator.  1, record 2, English, - condensate%20separator

Boiler Return Trap or Alternating Receiver. This type of trap is used to return condensate to a low pressure boiler. The boiler return trap does not hold steam as do other types, but is an adaptation of the lifting trap. It is used in conjunction with a boiler to prevent flooding return mains when excess pressure prevents condensate from returning to the boiler by gravity. The boiler trap collects condensate and equalizes the boiler and trap pressure, enabling the condensate in the trap to flow back to the boiler by gravity.  5, record 3, English, - boiler%20return%20trap

Pump and Receiver Systems. Condensate returns by gravity, not directly to the boiler, but to a receiver tank. When the water level in the boiler reaches a low level that requires the introduction of makeup, the pump is actuated by the boiler water-level controller and discharges the condensate into the boiler.  3, record 4, English, - receiver%20tank

Les eaux condensées sont recueillies dans une bâche où elles sont reprises par une pompe qui les réintroduit dans la chaudière. Comme la quantité d'eaux condensées ne correspond pas toujours aux besoins instantanés d'eau d'alimentation, la bâche de récupération doit pouvoir contenir une certaine réserve qui peut être de l'ordre de la consommation d'eau pendant 10 à 20 minutes en allure de pointe.  2, record 4, French, - b%C3%A2che%20de%20r%C3%A9cup%C3%A9ration

These same basic components may be used in the design of a vacuum or a subatmospheric system. The vacuum heating pump maintains a vacuum in the return piping under all operating conditions, assisting the supply steam in overcoming the resistance of the system piping and assuring rapid and uniform steam distribution.  2, record 5, English, - vacuum%20pump

Vacuum pumps are used on a system where the returns are under a vacuum. The assembly consists of a receiver, separating tank and automatic controls for discharging the condensate to the boiler. Vacuum pumps are sized in the same manner as condensate pumps for a delivery of 2. 5 to 3 times the design condensing rate.  2, record 5, English, - vacuum%20pump

If the air system is large enough in volume so that no air receiver is used, a condensate leg with drain valve should be placed in the piping at a joint as far from the compressor as possible and just ahead of the point at which the air is used.
