FIELD: machine building.
SUBSTANCE: air-gas counter-flow laminar matrix-circular compact ceramic recuperator consists of row of cylinder heat exchanging matrixes of various diametre arranged coaxially one in another. Also each matrix is made as a cylinder cartridge assembled as a pile of flat circular leaves-plates with holes and cross slits with specified circular step; the plates are designed for separate motion of air flows in them and for exhaust of hot gas. Notably, these air and gas flows never mix at their motion in space along spiral stepped cylinder channels and along short cross channels.
EFFECT: improved characteristics of common laminar recuperators used in gas-turbine installations of open cycle.
