Combined cycles utilizing fluidized bed combustors, whether they be atmospheric or pressurized, are temperature limited. In order to capture sulfur effectively, bed operating temperature and, therefore, the gas turbine inlet temperature is limited to about 1600/sup 0/F(1144 K) in atmospheric beds and about 1700/sup 0/F (1200 K) in pressurized beds as reported in DOE/METC/SP-185 (1980). In some applications, material limitations also come into play. While these systems show encouraging economics, they can be enhanced substantially by increasing the turbine inlet temperature. An atmospheric fluidized bed (AFB) example is discussed in this paper. Although emissions control and maintaining acceptable wall temperatures are achieved through the application of the multi-annular swirl burner, the design of such a combustor requires careful consideration of cooling and combustion because of the inherently higher cooling air and combustion air temperatures.
