Abstract: A coolable arched roof for a high-temperature melting furnace having a furnace interior. At least the following layers are present on that side of a layer of refractory bricks, which is remote from the furnace interior: a sealing layer, which is used to seal the furnace interior against the leakage or penetration of gas; an insulation layer having a thermally insulating action; and a cooling layer, which is designed to carry a cooling fluid. The arrangement of layers results in an increased gastightness and prevents premature aging of the refractory bricks.

Abstract: A loading method and loading device for feeding waste-filled containers into a rotary incinerator, wherein open topped containers are filled with liquid, pasty, or solid waste materials and are fed sequentially using a reciprocating ram via a slide onto a loading and dumping platform. This loading and dumping platform projects from the stationary incinerator inside wall into the drum of the rotary incinerator. Each container placed on the loading and dumping platform is allowed to stand for one loading time interval during which a portion of the combustible volatile components of the waste contents is gasified and burned by the heat radiating from the fire in the drum. After this initial combustion, the reciprocating ram feeds the next container in sequence onto the loading and dumping platform and, at the same time, tips the first container off the platform into the drum. The combustible waste residue of this tipped container spreads out on the lower wall of the drum and burns, releasing further heat.
