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 recirculation. The paper describes the methodology for setting up process parameters, heat duty, boiler design, including auxiliary equipment selection and advantages. The paper also updates the ongoing IR-CFB boiler contracts.
