The oxygen transport reactor-based oven is an oven for heating articles, such as bread, using oxygen transport reactor-based combustion in order to recycle carbon dioxide, rather than releasing the carbon dioxide into the environment. The oven includes an upper furnace chamber having a plurality of oxygen transport reactors disposed therein. A mixture of fuel and gaseous carbon dioxide is delivered to the interior of each oxygen transport reactor. Pressurized air is then delivered to the upper furnace chamber, so that oxygen from the pressurized air is driven through an ion transport membrane of each oxygen transport reactor to combust with the fuel. This combustion produces carbon dioxide, water vapor and heat. The generated heat is used to heat the articles to be heated, which are received within a heating chamber positioned beneath the upper furnace chamber.

1. An oxygen transport reactor-based oven, comprising: an upper furnace chamber defining an open interior region;a plurality of oxygen transport reactors disposed within the open interior region of the upper furnace chamber, each of the oxygen transport reactors having an ion transport membrane for unidirectional passage of oxygen through the membrane;means for delivering a mixture of fuel and gaseous carbon dioxide to an interior of each of the oxygen transport reactors;means for delivering pressurized air to the open interior region of the upper furnace chamber, whereby oxygen from the pressurized air is driven through the ion transport membrane of each of the oxygen transport reactors to combust with the fuel within the interior thereof, the combustion generating heat;a heating chamber for receiving articles to be heated;a radiator plate formed from a thermally conductive material separating a lower portion of the upper furnace chamber from an upper portion of the heating chamber, whereby the heat generated by the combustion heats the radiator plate, the heated radiator plate heating the articles within the heating chamber;a lower chamber positioned beneath the heating chamber;a continuous drive belt configured in a loop having an upper portion passing through the heating chamber for carrying the articles to be heated, and a lower portion passing through the lower chamber;means for removing gaseous nitrogen from the upper furnace chamber, the gaseous nitrogen being heated by the combustion; andmeans for delivering the gaseous nitrogen removed from the upper furnace chamber to the lower chamber for heating the lower portion of the continuous drive belt. 2. The oxygen transport reactor-based oven as recited in claim 1, further comprising means for removing water vapor and the gaseous carbon dioxide from the interior of each said oxygen transport reactor following the combustion of the fuel. 3. The oxygen transport reactor-based oven as recited in claim 2, further comprising a heat exchanger for transferring heat from the water vapor and the gaseous carbon dioxide removed from the interior of each said oxygen transport reactor to the pressurized air delivered to the open interior region of said upper furnace chamber. 4. The oxygen transport reactor-based oven as recited in claim 3, further comprising means for cooling the water vapor and the gaseous carbon dioxide after passing through the heat exchanger to produce liquid water from the water vapor for removal thereof, the gaseous carbon dioxide being recycled by said means for delivering the mixture of the fuel and the gaseous carbon dioxide to the interior of each said oxygen transport reactor.
