In the partial oxidation concept, a high pressure, low-heating-value fuel gas is generated by partially combusting fuel with air. This fuel gas is expanded in a high-pressure turbine prior to being burned in a second-stage, conventional combustion turbine. This process reduces the specific air requirements of the power system and increases the power output. The performance, practicality, and cost of a heavy duty combustion turbine power system incorporating partial oxidation (PO) of natural gas has been estimated to assess the potential merits of this technology. Compared to conventional combustion turbine power cycles, the PO power cycle shows the potential for significant plant heat rate and cost-of-electricity improvements. However, significant development remains to verify and commercialize PO for combustion turbine power systems.
