ABSTRACT:
Heat exchange apparatus comprises a generally cylindrical tank having an inlet port for entry of gas and an outlet port for exit of the gas after it is cooled, and an annular bundle of tubes disposed within the tank. The tank includes a cylindrical side wall or shell which encloses the tube bundle, and upper and lower annular manifolds for controlling flow through the tube interiors. The tank inlet port is located centrally of the upper annular manifold, and the tank outlet port is located on the shell. The annular tube bundle has a generally cylindrical interior having a longitudinal axis parallel to that of the shell. The interior of the annular tube bundle is aligned with the inlet port so that the interior of the tube bundle functions as an inlet plenum for the gas entering the recuperator. The annular tube bundle is radially offset from the center of the tank so that an eccentric outlet plenum is provided between the tube bundle and the shell for flow of gas circumferentially and axially of the shell toward the outlet port.
