Abstract

This paper presents two simplified and approximated relations of heat transfer effectivneness for steam condenser. The proposed relations of heat transfer effectivneness are a function of the measured and reference parameters. Correctness of relations were verified on the basis of data from the characteristics and measured data for the 200 MW steam condenser. A comparison of the outlet cooling water temperature calculated from the proposed relations and Beckman formula were performed. Formula proposed by Beckman for steam condenser of heat transfer effectivneness, in simplified form, is a function of saturation temperature, mass flow rate of cooling water and the reference parameter. It contains two constant exponents, which must be determined on the basis of the measured data. To assess the accuracy of the correlations the average value and standard deviation were used. The proposed correlations have simpler forms, but are slightly less accurate compared to the Beckman correlation.
