%0 Journal Article %T A mathematical model of the steam condenser in off-design operation %A Rafal Marcin Laskowski %J Journal of Power Technologies %D 2012 %I Warsaw University of Technology %X The paper presents a mathematical model of a steam condenser in the changed conditions. A list of independentparameters on which the water temperature at the outlet from the steam condenser depends was selectedand by means of the Buckingham theorem a functional relation between two dimensionless quantities wasobtained. The exact form of the function was determined on the basis of data from the characteristics ofsteam condenser for a 200 MW power plant and actual measurement data for dierent condenser operatingin a power plant of 200 MW. A linear relation between two dimensionless quantities was obtained. Thecorrectness of the proposed relation was examined by comparing the measured temperature and calculatedtemperature from the proposed relation. %K Heat exchange %K condenser %K off-design %U http://www.papers.itc.pw.edu.pl/index.php/JPT/article/view/295/486
