Dry cooling - Import export

An indirect dry cooling system is characterized by the use of a condenser and air-cooled heat exchangers.The cooling system consists of the following main components :condenser (surface or spray type),cooling water circulating pumps and recovery turbines, if applicable,heat exchanger deltas including louvers,natural draft cooling tower,piping and valves,water storage tanks and transfer pumps,electrical equipment,instrumentation and control,accessories such as cleaning system, nitrogen blanketing system,The warm water from the condenser is delivered to the natural draft cooling tower by the cooling water circulating pumps and an underground piping network. After the cooling in the heat exchangers, the cold water returns to the condenser.

The RCDC ACC is designed with optimized key sections and equipment to guarantee a maximized efficiency. The steam flows from the turbine into a steam duct and several manifolds to reach the fin tube bundles. The RCDC ACC is designed in streets sitting on a steel leg system (under structure) raised to allow proper air intake into the forced draft modules of A-shape steelframes supporting the fin tube bundles. Once condensed the steam is collected by gravity into a condensate tank located underneath or in the close vicinity of the ACC. The efficiency of the steam condensation process is guaranteed using appropriate and reliable vacuum units. RCDC guarantee the complete system and undertake integral studies related to the ducts and manifolds, the steel leg system and the pipe work and other special studies as appropriate.
