Direct Dry Condensing: Air Cooled Vacuum Steam Condensers
Air-cooled Vacuum Steam Condensers (= ACC) are designed to condense exhaust steam from turbines with pressure below 0.300 gauge bar. Heat exchange surface is an assembly of finned tubes, fed by an inlet steam duct and manifold, condensates are drained down into bonnet header boxes. Finned tube bundles are sloped in a A frame structure, they are blown by fans and drivers electrically driven.
Multiple row concept: MASH©
GEA Batignolles Technologies Thermiques 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.
Single row concept: ALEX©
GEA Batignolles Technologies Thermiques alternative design is based on single row concept : ALEX©. Steam flows down across 1 row of finned tubes whose section is almost rectangular. Non condensables go up through deflegmator bundles for final condensation. Advantage is noise power and pressure drop air side.
PID and Auxiliaries
Basic and detailed engineering for auxiliary equipments are carried out under 1 roof by a dedicated team using the latest tools to offer a complete performance guarantee.
 
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.
