A mathematical model of the steam condenser in off-design operation

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.
