Transient numerical analysis of charging a heat accumulator in a combined heat and power plant

This paper presents a technical description and characteristics of heat accumulation system operation in one of the Polish combined heat and power (CHP) plants. The total thermal capacity of the nonpressure hot water accumulator is 75 MWh. An important issue in the case of hot water tanks is thermal...
