Abstract
A semi-closed combined cycle power system is provided which can also convert an open combined cycle gas turbine into a non-polluting zero emissions power system. The exhaust is not emitted into the atmosphere as with typical open combined cycles, but rather is routed to a divider. The divider splits the exhaust into either a return duct or a separation duct. The return duct routes a portion of the exhaust back to the compressor. Before reaching the compressor, an oxygen duct adds additional oxygen to the exhaust to form a gas mixture which includes and steam from the exhaust and oxygen from the oxygen duct. This gas mixture has characteristics which mimic those of air, so that the compressor need not be modified to effectively compress the gas mixture.
