Apparatus for burning waste material
First Claim
1. Apparatus for burning material and utilizing the heat of said burning, comprising a primary combustion chamber having an upper portion vented to the atmosphere, means for feeding said material into the primary combustion chamber, a secondary combustion chamber in communication with a lower portion of the primary combustion chamber, means for supplying air into the secondary combustion chamber, fan means operable to draw air from the atmosphere into the upper portion of the primary combustion chamber and to draw combustion gases downwardly through burning waste material in the primary combustion chamber to cause further combustion of the combustion gases in the secondary combustion chamber by air supplied thereto, with combustion gases from the primary combustion chamber venting to the atmosphere from the upper portion of the primary combustion chamber when the fan means is inoperative.

Abstract
Apparatus for burning material and utilizing the heat of burning has a primary combustion chamber with an upper portion vented to the atmosphere, the material being fed into the primary combustion chamber. A secondary combustion chamber is in communication with a lower portion of the primary combustion chamber, and air is supplied into the secondary combustion chamber. A fan draws air from the atmosphere into the upper portion of the primary combustion chamber and draws combustion gases downwardly through burning waste material in the primary combustion chamber to cause further combustion of the combustion gases in the secondary combustion chamber. Combustion gases from the primary combustion chamber are vented to the atmosphere from the upper portion of the primary combustion chamber when the fan is not operating.
