Comparison of two simple mathematical models for feed water heaters
AbstractThe paper presents two mathematical models of feed water heaters. In the models the mass and energy balance equation and Peclet law are used. In the first model, a simplified one, there is no division into three zones, the heat exchanger is treated as a single zone and for such a heat exchanger the mass and energy balance equation and Peclet law are written. In the second model the heat exchanger is divided into three zones and for each zone the mass and energy balance equation and Peclet law are written. The accuracy of models was examined on the basis of real data. For both models a comparison between water temperature at the outlet of the exchanger measured and calculated was performed.
