Powell, E R

A flue heat recovery device for furnaces or boilers comprises a rectangular housing with a corrosion-resistant or corrosion-proof wall in the housing dividing the space into an air chamber and a flue gas chamber. The flue gas chamber has a gas inlet opening which can be connected to the flue of a furnace, and a gas outlet opening for discharging the flue gas from the flue gas chamber to a chimney. The air chamber has an air inlet and an air outlet, with a fan connected to the outlet for drawing air through the air chamber in a direction opposite to the flow of flue gas in the flue gas chamber. A plurality of finned heat pipes extend through the corrosion-proof wall from the flue gas chamber into the air chamber. The chambers are mounted on a base tray with the air chamber supporting the heat pipes and separable from the flue gas chamber for cleaning.
