Wood burning stove

Abstract

A wood stove defining an upper combustion chamber and a lower fire box having two inwardly and downwardly angulated opposed fuel chutes for gravitational feeding of fuel to the fire box for extended burning. A rectilinear air channel spaced apart from a back wall of the stove, and structurally attached thereto, provides a channel for combustion products and byproducts to pass from an upper inner portion of the stove adjacent a chimney port downwardly to the fire box to pass through the primary fire zone for more complete combustion of the combustion products and combustion byproducts to enhances heat production and reduce wasting of smoke generating particulates and vapors.

Description

II. BACKGROUND OF INVENTION[0001]IIA. Related Applications[0002]There are no applications related hereto heretofore filed in this or in any foreign country.[0003]IIB. Field of Invention[0004]This invention relates to stoves and furnaces, and more particularly to a stove having a downdraft air feed and a fuel supply hopper.[0005]IIC. Background and Description of Prior Art[0006]Combustion is the rapid oxidation of fuel with the release of heat and light. Byproducts of combustion are vapors, including partially combusted fuel, and carbon particulates that are wasted to the atmosphere.[0007]Combustion occurs in two stages. First, volatile gases are liberated from the fuel. Second, the volatile gases are oxidized when they are ignited in the presence of oxygen. The heat released in the oxidation liberates more volatile gasses from the fuel. Ignition of the gasses leads to more oxidation which generates more heat. The process continues so long as there is fuel and oxygen.[0008]Oxidation ...

[0024]a further object to provide such a stove that is more fuel efficient.

Problems solved by technology

Second, the volatile gases are oxidized when they are ignited in the presence of oxygen.

Above, below, and adjacent the primary fire zone temperatures are not sufficient to ignite the volatile gasses, leading to incomplete combustion.

Incomplete combustion generates large quantities of carbon particulates and vapors that are wasted to the atmosphere.

The rising heat and gasses create updrafts.

Unfortunately, known methods and apparatus use fresh air rather than combustion products.

Further, known methods and apparatus require moving parts and energy sources, such as electricity, which makes such apparatus prone to break downs, operating inefficiencies, needing regular maintenance, and causing higher manufacturing costs.

The result is an additional portion of the combustion products are combusted by passing through the primary fire zone more than once which decreases the amount of these materials being wasted to the atmosphere.
