Direct Dry Condensing: Air Cooled Vacuum Steam Condensers

Air Cooled Condensers supplied by GEA provide an efficient and reliable steam condensation system for the power and process industries. With the development of more than 60 years of successful experience, increasing environmental constraints and restricted water availability make the Direct Condensing technology even more prevalent today.

GEA technology has continuously evolved through the development of various designs, configurations and materials, representing the state of the art technology in Direct Condensing. The GEA was given a turn-key contract in 1982 for the design, manufacturing, supply, erection and commissioning of six air-cooled steam condensers for Eskom’s 6x665 MW Medupi Power Station in South Africa, which stands today as the largest direct air-cooled steam condenser installation in the world.

Multiple row concept

GEA Batignolles Thermal Technologies (Changshu) Co., Ltd. prime design for Vacuum Air Cooled Condensers is based on MASH© concept. Steam is brought to the condenser via steam duct and a manifold. Steam flows down across 2 or 3 rows of finned tubes. Condensates are recovered inside bonnet header boxers connected to a hot water tank. Non condensable goes up through a deflegmation row for final condensation.

Structure design

From general arrangement drawing, we are able to generate a 3D model in order to perform calculation using Staad-pro© software. This model is then exported to X-steel© software to produce all detail and shop drawings.
