<p>A description is given of an apparatus (1) for treating a bed (2) of particulate material which is supported by an aeration bottom (3), subject to the application of a conditioning gas being directed to and flowing up through the aeration bottom (3) and the material bed (2) from an underlying compartment (4) which comprises side walls (5), end walls (6) and a bottom (7). The apparatus is peculiar in that it comprises a space (8) for inspection which extends into the compartment (4) from one of its side walls (5), end walls (6) or bottom (7) and allowing access for a person for visual inspection by direct sight of the compartment (4) through a number of inspection openings (9). Hence it will be possible during the operation of the apparatus to inspect by direct sight the equipment in a significantly extended area of the compartment. This is due to the fact 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.</p> |
