REGENERATIVE HEAT EXCHANGER, RADIAL SEAL FOR SUCH HEAT EXCHANGER AND METHOD OF SEPARATION OF GASEOUS MEDIA IN REGENERATIVE HEAT EXCHANGER Russian patent published in 2010 - IPC F28D17/00 

FIELD: power industry.

SUBSTANCE: heat accumulator of regenerative heat exchanger includes many radial sector walls which divide heat accumulator into sectors. Within the sector there provided are at least two heat accumulating chambers which are located one after the other in radial direction. On end surface of heat accumulator there located are radial seals containing at least two sealing branches, and at least one sealing branch is asymmetric and provides the covering of not all heat accumulating chambers of sector, which are simultaneously located one after the other in radial direction.

EFFECT: decreasing the inflation of seals and leakage between areas of various gases, as well as wear and tear of radial seals and end surfaces of heat accumulator.
