B&W's two-stage particle separation system results in a compact, simplified boiler arrangement. The entire U-beam particle separator is located at the furnace exit. Compared with hot cyclone-type CFB designs, the IR-CFB has significantly lower furnace exit gas velocity and requires significantly less building volume. By relying on internal recirculation, the IR-CFB design eliminates J-valves, loop seals, and high-pressure blowers which are required with other CFB designs. For the IR-CFB, compact and simple equals economical.
