Condensers in which the steam or vapour is separated from the cooling medium by walls, e.g. surface condenser

using water or other liquid as the cooling medium

employing moving walls

using air or other gas as the cooling medium

employing moving walls [3]

Condensers in which the steam or vapour comes into direct contact with the cooling medium

by providing a flowing coating of cooling liquid on the condensing surface

by injecting cooling liquid into the steam or vapour (F28B 3/08 takes precedence)

by injecting the steam or vapour into the cooling liquid (F28B 3/08 takes precedence)

with rotatable members

Condensers employing a combination of the methods covered by groups F28B 1/00 and F28B 3/00; Other condensers

Combinations of two or more condensers, e.g. provision of reserve condenser

Auxiliary systems, arrangements, or devices

for feeding steam or vapour to condensers

for feeding, collecting, and storing cooling water or other cooling liquid

with provision for re-cooling the cooling water or other cooling liquid

for collecting and removing condensate

for extracting, cooling, and removing non-condensable gases
