Abstract
This invention relates to fluidised bed combustion systems and facilitates the maintenance of the depth of the bed. A discharge pipe projects upwardly into the bed so that bed material can flow into its upper end and escape downwardly. The end of the pipe is surrounded by an enclosure and air is discharged into the enclosure so that material will enter the pipe from within the enclosure and have been cooled in the enclosure by the air discharged into it. The walls of the enclosure may themselves be cooled. The invention is illustrated in FIG. 1.
