abstract

Westinghouse has developed a rich-quench-lean gas turbine combustor for use on multiple gaseous fuels. The design is based on variants of the Multi-Annular Swirl Burner (MASB) that was invented as a low-NOx topping combustor for the second generation PFBC process, utilizing high temperature vitiated air and high temperature NH3-rich fuel gas, both derived from coal. This Westinghouse RQL combustor is also capable of low-NOx performance using either natural gas or propane in vitiated air, as well as compressor air operation using syngas (coal- or biomass-derived fuel gas for IGCC), propane, or natural gas. The current status of the Westinghouse RQL combustor with regard to each such application is discussed, including design basis, design status, test experience, and expected emissions and operating characteristics.
