Through the support of the US Department of Energy, Clean Energy Systems, Inc. and its development partners have designed, manufactured, and tested and industrial-scale oxy-fuel turbine, suitable for applications in oxy-combustion power cycles that capture greater than 99% of produced carbon dioxide. To save on development cost and schedule, a used industrial gas turbine, an SGT-900 811/12 engine, was purchase, disassembled and inspected, then retro-fitted to act as an intermediate-pressure, hot gas expander. Also, the engine's air-breathing combustors were converted into oxy-fuel reheaters to boost turbine inlet temperatures and therefore, cycle efficiencies. A dedicated test rig was designed, fabricated, instrumented, and installed at an existing test facility to demonstrate reheater performance prior to install and operations within the oxy-fuel turbine. Component test results prove the feasibility of gas turbine conversion to oxy-fuel turbine, however further testing is recommended to further verify performance at higher power levels, and longer durations.
