Worldwide, the use of Circulating Fluidized-Bed (CFB) boiler technology is rapidly increasing due to the ability to burn low grade fuels while meeting the required NO{sub x}, SO{sub 2}, CO, VOC, and particulate emissions requirements. The CFB boiler can produce steam economically for process and electric power generation. This paper discusses various aspects of Babcock & Wilcox (B&W) internal recirculation circulating fluidized-bed (IR-CFB) boiler design including fuel, boiler process parameters, and emissions. The B&W CFB boiler is unique in design. It utilizes proven impact-type particle separators (U-beams) with in-furnace solids recirculation. The paper describes the methodology for setting up process parameters, heat duty, boiler design, including auxiliary equipment selection and advantages.
