Abstract
A combustion system including an ion transport membrane assembly coupled to an internal combustion engine to generate power via oxy-combusting a fuel stream in a combustion chamber of the internal combustion engine, and a method of combusting the fuel stream via the combustion system, wherein a portion of an exhaust stream is recycled to the ion transport membrane assembly. Various embodiments of the combustion system and the method of combusting the fuel stream are disclosed.
Claims8
A combustion system, comprising:
- an ion transport membrane assembly comprising
- a vessel with an internal cavity, and
- a plurality of ion transport membranes that separate the internal cavity into a feed zone and a plurality of permeate zones, wherein the feed zone has a feed inlet and a feed outlet and each permeate zone has a sweep inlet and a sweep outlet;
- a combustion chamber comprising
- an oxygen inlet,
- a fuel inlet, and
- at least one exhaust outlet,
- wherein the combustion chamber is located downstream of and fluidly connected to the sweep outlet of the plurality of permeate zones via an oxygen line;
- a recycle line that fluidly connects the at least one exhaust outlet to the sweep inlet of the plurality of permeate zones;
- at least one of (i) a gas mixer disposed immediately upstream of the combustion chamber and fluidly connected to the oxygen inlet and the fuel inlet and (ii) a swirler disposed inside the combustion chamber;
- and
- a turbocharger comprising
- a compressor fluidly connected to the oxygen line, wherein the compressor is located downstream of the sweep outlet of the plurality of permeate zones and upstream of the oxygen inlet of the combustion chamber, and
- a turbine fluidly connected to the at least one exhaust outlet via an exhaust line,
- wherein the compressor and the turbine are coupled via a shaft.
