DESIGN STUDY OF CONDENSER AND CIRCULATION SYSTEM

Economical performance of steam condensers is controlled largely from the drawing board and computer room; not by the ships crew. The design characteristics of the condenser and circulation system determine condenser performance, except for the effect of tube cleanliness. Sea water for the circulation system varies from 35 to 82.5 degrees Fahrenheit over a wide range of commercial trade routes. However, on certain routes the variation is from 35 to 60 degrees; on others 65 to 82.5 degrees. A survey was made of sea water temperatures for selected trade routes, and results plotted graphically for design guidance. Study has been directed toward design of condensers and circulation systems for special purpose, and for universal type ship operations. A series pump-scoop arrangement is proposed to provide favorable control of flow through condenser. Variations in condenser and circulation system design are evaluated by a life cycle cost analysis. A computer program for calculating condenser design characteristics for checking condenser performance, and for analyzing scoop performance is appended.
