Device for heating two gas fractions on heat exchange with fumes.

摘要

Device for heating two gas fractions, which are different or at different pressures, on heat exchange with fumes deriving from the combustion of a fuel, in particular in a fluidised bed, comprising tubular bundles (1) which are passed through by the fumes and around which a first gas fraction to be heated circulates. It also comprises heat conduits (12) arranged between the trajectory of the first gas fraction and that of the second gas fraction.
