ABSTRACT:
A closure arrangement for an incinerator or cremator in which the door and the opening in the incinerator are complementary wedge-shapes is described. The door can be automatically lowered by a hydraulic actuator to close the opening by a wedging action in the vertical direction. The seal is enhanced by a sealing strip fastened around the periphery of the door which is compressed between the door and the opening when the door is closed. A hinge is connected between the door and the actuator which allows it to move laterally as well as vertically so that it can fit snugly into the opening. The door can also be raised to close the opening. In the case of large heavy doors the hinge can be omitted and the door may be raised or lowered using guides.
