This article is a comparison of the state of fluid-bed design with commercial pulverized coal fossil-fuel power plants. With successful operation of several units in the 100- to 200-MW range, designers have set their sights on a doubling of unit capacity. To compete with p-c units, however, comparable gains in efficiency, operability, environmental performance, and cost are necessary, too. In a decade or so, circulating fluidized-bed (CFB) boilers and bubbling-bed units have progressed from industrial-sized curiosities to several 150-200-MW single units operating today. A 250-MW CFB unit is being installed in France for startup in 1995, a 225-MW unit is being designed for installation as part of the US DOE Clean Coal Technology Demonstration program, two 230-MW units are slated to start up in Poland in 1995, and a 350-MW bubbling-bed unit is under construction in Japan. Thus, fluid-bed technology is poised to compete with pulverized-coal (p-c)-fired units for utility-scale applications. But size isn't everything. To fully compete, CFB designers have to consider thermal efficiency, environmental performance, operability, fuel flexibility, cost, and a host of other factors.
