Abstract:
1. A combustor-heat exchanger system comprising: a plurality of cans each comprising: an inner cylinder and an outer cylinder forming an annular space in between, wherein said inner cylinder is configured to receive and combust a fuel and compressed oxidant to generate heat and a hot gas and said outer cylinder is configured to receive a portion of a gas lean in carbon dioxide from a turbine system and utilize said heat from said inner cylinder to generate a heated gas; an inlet volute along the surface of said inner cylinder configured to receive said portion of said gas lean in carbon dioxide and distribute said gas lean in carbon dioxide into an axial flow through said annular space of each said can; and an outlet volute along the surface of said outer cylinder configured to receive said heated gas from each said can; a first manifold to distribute said gas lean in carbon dioxide stream into said each inlet volute; and a second manifold to receive said heated gas from each said can and generate a hot discharge stream.
