Technical Data Sheet: Water Systems Air Cooled Condensation Plants Strict restrictions for the use of cooling water and its limited The self supporting fin tube stacks manufactured at our works availability at many locations result in a growing demand are mounted as A-type on a steel support structure, below the tubes horizontal forced draught fans are located. A frequency control of the fan motor speed facilitates the adjustment of the Air cooled condensers manufactured by Hamworthy Serck fan speed to different heat loads and different ambient Como are especially suitable for the liquefaction of turbine temperatures, which results in a reduction of the running costs. exhaust steam at vacuum conditions. The use of low-noise fans enables Hamworthy Serck Como to install air cooled condensers near residential areas. Exhaust steam is passed through a high number of finned tubes. Hamworthy Serck Como employs finned tubes that At low atmospheric temperatures and reduced heat load there consist of a steel base tube and aluminium fins. One of the is a potential risk of freezing inside the finned tubes. By remarkable features of aluminium fins is their high heat designing a counter-current flow of steam and condensate conductibility and their high efficiency, and knurled tubes inside each tube bundle, Hamworthy Serck Como prevents the guarantee the necessary bondage between base tube and fins. In addition to supplying air cooled condensers we offer to our customers: engineering all necessary auxiliary and safety equipment switchgear cabinet for the control of the plant assembly and commissioning if desired we can include pipework, exhaust steam pipe, electric cabling and heat insulation Air cooled condenser in the set-up period

Air Cooled Condensation Plants Water Systems Flow diagram of a complete air cooled condenstion plant KEY Steam Condensate Inert gases/steam Control circuit Description of process One or two steam ejectors draw the inert gases off the cavitation-free operation of the pumps at low load, the level condenser that would otherwise accumulate during in the condensate tank is maintained constant by switching a vacuum operation. If necessary we can provide an three-way valve. Alternatively we supply water ring pumps as additional hogging ejector. The motive steam necessary for operating the ejectors is Two...
