Thermal energy storage (TES) can average the loads of thermal energy systems, thus increases their energetic and exergetic efficiencies. The steam boiler plant with violently fluctuating loads is a typical example when a steam accumulator is added to it. However, the comparatively big first cost constitutes a barrier to wide use of TES. The cost will notably be reduced through minimizing the necessary thermal capacity of TES. A computer program for performing the optimization is illustrated in the paper. This program was applied to an existing boiler plant equipped with a steam accumulator. The results show that there would have been a remarkable reduction in the necessary capacity, if the capacity of this steam accumulator had been optimized. Four conclusions have been reached.
