NEW METHODS OF THE CALCULATION OF THE FEED WATER HEATERS WITH THE APPLICATION OF THE CHARACTERISTICS

Łukasz Kurpisz

Abstract


A new conception of using of the characteristics for the mathematical modelling of the feedwater heaters is presented.

The principles of the chatacteristics contruction and the methods of the eliminaion of the independent variables are discussed.

The usefulness of the approximation for determination of the characteristics shape is estimated.

The comparison of the results of the computer calculations of the full scale models and the models simplified by the characteristics is shown.
