Regenerative heat exchanger system and an operating method for the same

摘要

A regenerative heat exchanger system includes a heat accumulator provided in an insulating vessel for accumulating heat energy, the heat accumulator having a first end and a second end opposing to the first end and being capable of permitting gas to flow through a body between the first and second ends, a heating device for heating the heat accumulator in such a manner that the heat accumulator is formed with a plurality of temperature-different regions, a medium gas-supplying device for flowing medium gas through the plurality of temperature-different regions independently from one another.
