<p>A circulating fluidized bed boiler comprises a fluidized bed combustion chamber (14), a recirculating system for recirculating fluidized solids through the combustion chamber, and a plurality of tubes (58) for withstanding supercritical pressure are disposed around the walls of the combustion chamber (14) for circulating cooling fluid between an inlet header (54) at the bottom of the chamber and an outlet chamber (56) at the top of the combustion chamber (14). A water steamseparator (66) directs steam to a superheater (70) and is bypassed during normal operation.</p> |
