Abstract

An apparatus for generating electrical power in which a synthesis gas stream generated in a gasifier is partially oxidized, expanded and thereafter, is combusted in an oxygen transport membrane system of a boiler. The combustion generates heat to raise steam to in turn generate electricity by a generator coupled to a steam turbine. The resultant flue gas can be purified to produce a carbon dioxide product.
