Wood burning furnace
Abstract
An improved furnace for burning wood is described which is resistant to creosote deposits from smoke. It consists of: an upright frame; a fire box carried by the frame and having a door for the insertion of the wood; a heat exchanger carried on the fire box and having an interior chamber with a top and bottom; means connecting the fire box and the heat exchanger and directing smoke from the fire box into the exchanger chamber; a chimney stack fixed to and extending upwardly from the exchanger to discharge smoke, the stack also extending substantially downwardly within the exchanger chamber to receive smoke from adjacent the bottom of the chamber to thereby retain hot smoke adjacent the top of the exchanger for an increased time interval to allow additional heat transfer from the smoke to the exchanger; an insulative housing carried on the frame to define an air plenum within the housing and about the fire box and exchanger to permit air in the plenum to be heated by contact with the fire box and the exchanger; and an air inlet for cold air to enter the plenum and an air outlet by which heated air may leave themore »
