Abstract

A heat exchange apparatus for removing magnetic particulates from a gas stream, including a rotating element basket having a regenerative heat exchanger and at least one magnetic element. A method of removing magnetic particulates from a gas stream, including heating the regenerative heat exchanger during a first portion of a cycle as a segment of the rotating element basket passes through a first zone wherein contact is made with a flue gas thereby accumulating any magnetic particulates as they are attached to the magnetic element. Then cleaning a portion of the magnetic element during a second portion of the cycle. And cooling the regenerative heat exchanger and simultaneously heating an inlet air stream during a third portion of the cycle as the segment of the rotating element basket passes through a third zone wherein fluidic contact is made with the air inlet stream.

A heat exchange apparatus for removing magnetic particulates from a gas stream, comprising:

a rotating element basket comprising a regenerative heat exchanger and at least one magnetic element,
a first zone wherein fluidic contact may be made with a flue gas stream, thereby heating the regenerative heat exchanger and accumulating at least a portion of any magnetic particulates present therein as they are attached to the at least one magnetic element,
a second zone wherein the at least one magnetic element may be cleaned, and
a third zone fluidic contact may be made with an air inlet stream, thereby cooling the regenerative heat exchanger and simultaneously heating the inlet air stream.
