  • Patent number: 8820312
    Abstract: 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.
