Abstract
A heat recovery system is provided for recovering heat from flue gases and the like and heating combustion air or the like in the form of a flue gas conduit receiving hot flue gas from a furnace or the like, a metallic recuperator receiving hot flue gas from said flue gas conduit, a ceramic regenerator selectively receiving at least a part of the hot flue gas leaving the metallic recuperator, by-pass means in parallel with the ceramic regenerator receiving any of the flue gas leaving the metallic recuperator which does not go through the ceramic regenerator, stack means receiving the flue gas from the by-pass means and the ceramic regenerator means for discharge to the atmosphere, means delivering air to be heated in parallel to the ceramic regenerator and the metallic recuperator, and conduit means receiving and combining heated air from the ceramic regenerator and the metallic recuperator for delivery to a point of use.
