(0100) Simplified correlation for steam condenser effectiveness under off-design conditions as a function of inlet parameters

Heat transfer effectiveness is used to assess the steam condenser performance. Heat transfer effectiveness of a steam condenser is a function of an overall heat transfer coefficient, heat transfer surface area and the cooling water mass flow rate. Beckman proposed a relation to describe the heat transfer effectiveness as a power function of inlet water temperature, cooling water mass flow rate and steam temperature. In this paper, an attempt was made to produce a simpler relation for heat transfer effectiveness of a steam condenser under off-design conditions. The proposed relation was verified against data obtained from performance curves and measurements at a 200 MW steam condenser. A good agreement was achieved between the heat transfer effectiveness obtained from the definition and from the proposed relation.
