A heat recuperator is disclosed having a plurality of serially connected tube sections enclosing a gas which is to be heated by exposing the tube sections to a second gas of elevated temperature. Parallel-flow and/or counter-flow sections of tube sections are provided such that the temperature of the tube section does not decrease below the dew point of the second gas. A particularly significant application is in the area of Compressed Air Energy Storage (CAES) systems in which the recuperator is utilized to preheat air from a storage cavern prior to com...
A method for heating high density and low temperature compressed air in a recuperator having a plurality of exhaust gas sections, each such section having associated therewith a tube section which is sufficiently heated so as to prevent the formation of corrosive condensate thereon, comprising the steps of: heating said compressed air initially in a first exhaust gas section and corresponding tube section wherein said first exhaust gas section and corresponding tube section operate in a parallel-flow manner; and heating said initially heated air in a sec...
