<p>The grid has a set of longerons (4) each having an inner end (11) placed near a symmetric vertical plane of an exhaust duct and an outer end (12) placed near a wall of the duct. The longerons are fixed to a common pivot pin (5) in a removable manner, where the pivot pin is perpendicular to the longerons. A set of crosspieces (19) is fixed to the longerons via bolts in a removable manner. The cross pieces are inclined with respect to the longerons so that each crosspiece has a V profile which turns its concavity towards the pin. An independent claim is also included for a method of assembling a screening grid.</p> |
