Carbon-free low-nox liquid fuel oxygen transport rector for industrial water tube boilers

A liquid fuel oxygen transport reactor, comprising:

• an outer oxygen transport membrane in the form of a cylinder having an upstream end and a downstream end,
• an inner porous membrane in the form of a cylinder having an upstream end and a closed downstream end,
• a liquid fuel injector, and
• a gas-assisted fuel atomizer;
• wherein the inner porous membrane is positioned inside the outer oxygen transport membrane to form an annulus between the outer oxygen transport membrane and the inner porous membrane,
• wherein the upstream end of the inner porous membrane is positioned at the downstream end of the outer oxygen transport membrane,
• wherein the liquid fuel injector and the gas-assisted fuel atomizer are located at the upstream end of the inner porous membrane,
• wherein the inner porous membrane is configured to pass a gaseous fuel and the outer oxygen transport membrane is configured to separate oxygen from a feed gas and pass the oxygen into the annulus, and
• wherein the annulus defines a combustion chamber in which the oxygen passed through the outer oxygen transport membrane and the fuel passed through the inner porous membrane react.
