ABSTRACT:
A fluidized bed boiler and a high temperature separator used therein. Each separator consists of a horizontal S-shaped passage formed in a casted block and having an inlet for receiving flue gases from the boiler. A divider wall divides a portion of the passage into a dense-phase gas bypass and a vertical-flow ash collecting chamber. As a result flyash of a diameter (50 .mu.m) can be separated, and the combustion cycle efficiency can reach over 98%.
