Duct for conditioning dusty gases by evaporative cooling

摘要

A duct (20) for the conditioning of dusty gases by evaporative cooling comprising: an outer supporting shell (24); a metallic structure (25) comprising one or more adjacent longitudinal portions (21, 22, 23) which are arranged inside the outer shell (24) and comprise one or more metallic panels being rigidly coupled to the outer shell (24) so as to have at least one first surface which is adapted to form a region for the flow of the dusty gases (5). At least one of the metallic panels is rigidly coupled to the outer shell so that it can be subjected to a transverse load which is adapted to move the first surface substantially at right angles to the main direction of motion of the dusty gases (5).
