Heat recovery coils are typically 4 or 6 row coils with a lot of fins per inch of tube and are expensive. I think the price of copper has made them less economic than they were 15 or 20 years back.

The content of the exhaust stream may be of concern for the coils, you would have to verify that the coil construction is suited to the environment.
