Barometric Surface Condenser for Utility Boilers
A vertical shell-and-tube condenser with extended tailpipe for gravity removal of condensate, used in large utility boiler steam cycles. It meets HTS 8404.20.00.00 as auxiliary condenser for steam power units, enabling high vacuum operation for turbine efficiency. Cooling water flows through tubes while steam condenses on the shell side.

Surface Condenser for Steam Turbine Power Plant
A large shell-and-tube heat exchanger designed to condense exhaust steam from a steam turbine in a power generation facility by cooling it with circulating water. It falls under HTS 8404.20.00.00 as a condenser specifically for steam power units, auxiliary to boilers in headings 8402 or 8403. The low-pressure exhaust steam is condensed into water for reuse in the boiler cycle.
