steam condenser


Air Cooled  steam Condensers directly condense exhaust steam from the steam turbine and return condensate to the boiler without water loss. They are frequently used in electrical power plants and waste to energy plants of all sizes. This constitutes the largest direct air-cooled steam condenser installation and, therefore, the largest direct air-cooled power station operating in the world.The GEA air-cooled steam condenser highly efficient and durable finned tubes, and a single-pressure two-stage condensing process.
The GEA air-cooled steam condenser is comprised of finned tube bundles grouped together into modules and mounted in an A-frame configuration on a concrete or steel support structure. Vertical and horizontal configurations are also available.

Scope :

The typical scope for an ACSC installation includes the supporting structure, the steam ducting from the steam turbine interface, auxiliaries such as the condensate and drain pumps, condensate and duct drain tanks, the air evacuation units and related piping works and instrumentation.

Features :

It is a direct dry cooling system where the steam is condensed inside air-cooled finned tubes.  Since there is no intermediate surface condenser like Indirect Dry Cooling, the overall performance is better.
The SPX Condenser features long-term mechanical and thermal integrity, excellent corrosion and freeze resistance, low fan power consumption, reliable operation and low maintenance.
It is made of modules arranged in parallel rows. Each module contains a number of fin tube bundles. An axial flow, forced-draft fan located in each module forces the cooling air across the heat exchange area of the fin tubes.
