The Siemens Westinghouse Multi-Annular Swirl Burner (MASB) is a rich-quench-lean gas turbine combustor for use primarily on synthetic fuel gases made by gasifying solid fuels (coal or biomass). These fuels contain high amounts of fuel bound nitrogen, primarily as ammonia, which are converted to molecular nitrogen rather than to nitrogen oxides in the rich zone of this combustor. The combustor can operate in many modes. In second-generation pressurized fluidized bed combustion (PFBC) applications, the fuel gas is burned in a hot, depleted oxygen air stream generated in a fluid bed coal combustor. In 1-1/2 generation PFBC applications, natural gas is burned in this vitiated air stream. In an integrated gasification combined cycle (IGCC) application, the synthetic fuel gas is burned in turbine compressor air. In this paper, the MASB technology is described. Recent results of tests at the University of Tennessee Space Institute (UTSI) for these various operation modes on a full scale basket are summarized. The start-up and simple cycle operating experience on propane at the Wilsonville Power Systems Development Facility (PSDF) are also described. In addition, the design issues related to the integration of the MASB in the City of Lakeland PCFB Clean Coal Demonstration Project is summarized.
