A Surface Condenser creates the lowest possible vacuum
or process operating back pressure while condensing steam.
The condensate generated is usually recirculated back into
the boiler and reused. Both these functions are accomplished
at the best efficiency consistent with the ever-present problem
of economy.
The bare condenser consists of the following parts :
Exhaust connections for turbine, condenser shell, shell expansion
joints, dome area, air off takes, hotwell, support saddles,
waterbox, pass partitions, water outlet connection, impingement
protection, tube support plate, tubes, shell flange, relief
valve connection, condensate outlets, tubesheets, water cover
& flanges, water inlet connection and handlehole.
