Air-cooled condesers
An air-cooled condenser is a direct-dry cooling system. In the thermal cycle, it condenses the exhaust steam of the steam turbine or the process steam in a vacuum. The air-cooled condensers are divided into two designs based on the arrangement of the cooling air fans: the classic A-form and the V-form.
A-Type
The steam flows through the exhaust steam pipe 1 at the top into the heat exchanger tubes 2 where it condenses. The condensate 3 flows geodetically into the condensate tank. The fan 4 pushes the cooling air 5 upwards through the heat exchanger tubes. The non-condensing gases are discharged via an exhaust air collector 6.
V-Type
The steam flows through the exhaust steam pipe 1 at the bottom into the heat exchanger tubes 2 where it condenses. The condensate 3 flows geodetically into the condensate tank. The fan 4 draws the cooling air 5 upwards through the heat exchanger tubes. The non-condensing gases are discharged via an exhaust air collector 6.
Our services
Innsopin offers services for air-cooled condensers in the following project phases according to the SIA 112 service model:
