Abstract
A fire tube boiler system including a plurality of oxygen transport reactors that heats a working fluid. Each oxygen transport reactor has a first inner tube with an ion transport membrane that receives air from a first supply line, extracts oxygen from the air, and evacuate oxygen depleted air through a first exhaust line, a second inner tube that surrounds the first inner tube that receives the oxygen from the ion transport membrane and a mixture of fuel and carbon dioxide from a second supply line and produces a oxy-combustion, and an peripheral tube that surrounds the second inner tube and evacuates the exhaust gases produced by the oxy-combustion and transfer heat from exhaust gases to the working fluid and the ion transport membrane.
Claims20
A fire tube boiler system comprising:
- a vessel that contains a working fluid;
- a plurality of oxygen transport reactors that is positioned inside the vessel and that heats the working fluid;
- a first supply line that provides air to the plurality of oxygen transport reactors;
- a second supply line that provides a mixture of fuel and carbon dioxide to the plurality of oxygen transport reactors;
- a first exhaust line that evacuates oxygen depleted air from the plurality of oxygen transport reactors;
- and
- a second exhaust line that evacuates exhaust gases from the plurality of oxygen transport reactors,
- wherein
- each oxygen transport reactor of the plurality of oxygen transport reactors includes:
- a first inner tube having:
- an upstream end that connects the first supply line to receive the air,
- a downstream end that connects the first exhaust line to evacuate the oxygen depleted air, and
- an ion transport membrane that connects the upstream end with the downstream end to extract oxygen from the air and form the oxygen depleted air;
- a second inner tube that surrounds the first inner tube to receive the oxygen from the ion transport membrane and that connects the second supply line to receive the mixture of fuel and carbon dioxide to react with the oxygen in a oxy-combustion;
- and
- a peripheral tube that surrounds the second inner tube and connects the second exhaust line through an upstream end to evacuate the exhaust gases produced by the oxy-combustion and transfer heat from exhaust gases to the working fluid and the ion transport membrane.
