Abstract
The paper presents dynamic model of hot water storage tank. The literature
review has been made. Analysis of effects of nodalization on the
prediction error of generalized finite element method (GFEM) is provided.
The model takes into account eleven various parameters, such as: flue
gases volumetric flow rate to the spiral, inlet water temperature, outlet
water flow rate, etc. Boiler is also described by sizing parameters,
nozzle parameters and heat loss including ambient temperature. The model
has been validated on existing data. Adequate laboratory experiments were
provided. The comparison between 1-, 5-, 10- and 50-zone boiler is
presented. Comparison between experiment and simulations for different
zone numbers of the boiler model is presented on the plots. The reason of
differences between experiment and simulation is explained.
