Abstract: By means of a software product named “Evaporating”developed and realized in Visual Basic, parametric numeric calculations were carried out aiming to estimate the influence of different energy supply of multi-effect evaporators on heat consumption for a plant depending on ultimate concentration of black lye. The program has been tested, using experimental researches by other authors, by estimating the influence of different energy supply of evaporators on the performance capabilities of black lye evaporated, namely its density, heat capacity, concentration of the product by blocks and other parameters. It is shown that it is possible to estimate the minimal heat increase of heating agent with different ranges of changes of concentration of the evaporated product.
