Direct air cooled condenser system Solve the problem of high water consumption in power station Applicable to water shortage areas, water saving > 85% 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.

Scope normally covers equipment and ducting from the outlet of the turbine low pressure cylinder to the inlet of the condensate pump, including: 1、Tube bundle 2、Air supply system 3、Air evacuation system 4、Condensate system 5、Cleaning system 6、Exhaust steam ducting system 7、Supporting structure 8、Draining system 9、Electrical system 10、Instrument & control system

1) Three test devices Performance Testing Device for tube bundles It is mainly used for heat transfer performance test of various finned tube bundle structures and on-line sampling test of finished products. The heat transfer coefficient and wind resistance of the tube bundle at different wind speed and the internal flow resistance of the tube bundle at different steam velocity are obtained by simulating several running back pressures of the steam turbine and testing the heat transfer performance and resistance loss of the tube bundle.At the same time, it is also used to verify the thermal...
