Abstract:
An integrated system for producing steam with minimal Nox formation, comprising:an oxygen transport membrane cell containing a first oxygen selective ion transport membrane that has a first cathode side and an opposing first anode side and is at a temperature effective for the transport of oxygen from said first cathode side to said first anode side; a boiler furnace including a combustion site within said boiler for supporting combustion of a diluted mixture of oxygen and fuel to raise steam; a conduit extending from said oxygen transport membrane cell to said combustion site for transport of at least one component of said lean mixture of oxygen and fuel; and a convective boiler connected to said first cathode side of said oxygen transport membrane cell to receive an oxygen-depleted feed gas and thereby generate further steam.
