Oxy-fuel combustion system having monolith membrane

An oxy-fuel combustion system comprising:

• a fuel source, a feed gas source and a monolith structure ion transport membrane reactor,
• wherein the monolith structure ion transport membrane reactor comprises a plurality of first and second ionic ceramic membranes that separate oxygen from a feed gas to form an oxygen-containing gas, wherein the first and second ionic ceramic membranes are oriented lengthwise and the first ionic ceramic membranes form first walls and the second ionic ceramic membranes form second walls defining a plurality of alternately stacked feed channels and permeate channels;
• wherein the monolith structure ion transport membrane reactor is fluidly connected to the feed gas source at an upstream end,
• wherein the plurality of feed channels and the plurality of permeate channels are present in the monolith structure ion transport membrane reactor formed by the first and second ionic ceramic membranes;
• wherein each permeate channel has a fuel inlet at upstream end of the reactor and each feed channel has an oxygen-containing gas inlet at an upstream end of the reactor;
• wherein the feed gas source is connected to the monolith structure ion transport membrane to pass a feed gas through the first and the second ionic ceramic membranes to separate the oxygen-containing gas from the feed gas and to react the oxygen-containing gas with a fuel gas present in the permeate channels to create a flame;
• wherein the monolith structure ion transport membrane reactor has a east 5 000 permeate channels in inch the oxygen gas and the fuel gas combust;
• and
• wherein the permeate channels have a width of 1-15 mm.
