STEAM OR VAPOUR CONDENSERS (condensation of vapours B01D5/00; steam engine plants having condensers F01K; liquefaction of gases F25J; details of heat-exchange and heat-transfer arrangements of general application F28F)

Introduced: September 1968

Description

F28B covers apparatus and systems designed to condense steam or other vapors into liquid form through heat exchange processes. The subclass encompasses condenser designs for power generation cycles, refrigeration systems, industrial processes, and related applications where vapor condensation is required. Specific technologies include surface condensers, contact condensers, air-cooled condensers, and specialized designs for vacuum or atmospheric pressure operation. Related heat exchangers for non-condensation applications are classified under F28D and other sibling classes within F28.
