ABSTRACT:
Flue dust precipitated from the compressed gas from a fluidized-bed combustion chamber is conveyed by flue gas to an air-lock system while simultaneously being cooled to above the water and acid dew point of the flue gas. As it enters the air-lock system, the dust is separated from the flue gas and, once it has left the air-lock system, the dust is conveyed by air while simultaneously being cooled to a final temperature at which it can be removed.
