ABSTRACT:
A processing plant involving the heat treatment of materials which are in finely divided state is provided with explosion relief means afforded by a door pivotally mounted across an opening in the wall of the plant. A lip of the door engages a resilient seal extending around the periphery of the opening, and the door is held in a closed position by a rupturable element which breaks when the pressure within the plant rises above a predetermined pressure to allow the door to open. There is additionally provided, extending across the door, an elongate tension member which is operative, subsequent to initial opening movement of the door, to apply a force to cause the door to return to its closed position, to minimise the subsequent drawing into the plant through the opening of air.
