An apparatus for treating a bed of particulate material supported by an aeration bottom

Abstract

A description isgiven ofan apparatus (1) for treatingabed (2) of particulate material which is supported by an aeration bottom (3), subjectto the application of a conditioning gds being directed to and flowing up,through the oration bottom (3) and the material bed (2) fronf an underlying compartment (4) which comprises side walls (5), end Walls (6) and a bottom (7). "Rie apparatus is peculiar in that it comprises a space (8) for inspection which extends Intathe compartment (4) from one of its side walls (5); end walls (6) or bottom (7) and allowing 'access for a person for visual nspection by direct sight of the compartment (4) through a number of inspection openings (9). Hence it Witt be possible during the operation of the apparatus to inspect by directsight the equipment in a significantly extended area of the compartment. This is due to thefact that the space for inspection makes it possible to inspect equipment located in areas of the compartment which are not visible due to poor . visibility from'windows located in the side walls of.the compartment.
