Direct acc air cooled condenser (ACC) is a type of heat exchanger commonly used in thermal power plants. It is designed to convert steam from the turbine exhaust into water, which can then be returned to the steam cycle. Unlike a conventional water-cooled condenser, a direct ACC uses air as the cooling medium, allowing for more compact design and reduced water usage. The steam is fed through a series of finned tubes, where it is cooled by the flow of air, which is generated by a forced draft fan.Operating Principle of Direct Air Cooled Condenser (ACC)It is a cooling system in which air is used as the cooling medium and the steam from the steam turbine's exhaust is immediately condensed into water through the tube bundle of the air-cooled condenser. Its air-cooled condenser, air supply system, support structure, exhaust duct system, condensate collecting system, vacuum-pumping system, cleaning system, electrical system, and instrument control system are the primary components of its heat exchange system.Features of Direct Air Cooled Condenser (ACC)01High thermal efficiency: Direct air-cooled condensers (ACCs) have a high thermal efficiency due to their finned tube bundles and large airflow, which allows for efficient latent heat transfer and ensures that the entire steam turbine exhaust is condensed.02Compact size: ACCs are designed to be compact and take up less space compared to conventional water-cooled condensers, making them suitable for installation in power plants with limited space.03Reduced water usage: ACCs do not require any water from an external source for cooling, making them more water-efficient than traditional water-cooled systems. This reduces the impact of the plant on the environment and results in potential cost savings for the power plant.04Reduced maintenance: ACCs have a simplified design and require less maintenance than water-cooled systems. There is less need for water treatment or mitigation systems to prevent leaks or corrosion, reducing maintenance costs for the plant.
