Air-cooled condenser

steamsteelfor air conditioning systems

The ACC system is to distribute the exhaust steam discharged by the steam turbine directly to each unit condenser through the pipeline. The large axial flow fan inhales air, skims the tube bundle from the outside, and takes away the heat. The steam condenses into water and goes through the bottom header under the tube bundle to the condensate tank. Direct Air Cooled Condenser System (ACC) The ACC system is to distribute the exhaust steam discharged by the steam turbine directly to each unit condenser through the pipeline. The large axial flow fan inhales air, skims the tube bundle from the outside, and takes away the heat. The steam condenses into water and goes through the bottom header under the tube bundle to the condensate tank. The air evacuation system maintains the vacuum of the whole ACC system, so that the steam turbine can run normally and ensure the efficiency of power generation. The condenser is divided into parallel-flow tube bundle and counter-flow tube bundle. Most of the steam condenses in the parallel tube bundle, the non-condensable gas is extracted in the counter-flow tube bundles, and the parallel-flow and counter-flow tube bundles are connected through the condensate tank at the bottom. ACC has the advantages of less area, various anti-freezing methods and flexible arrangement.
