摘要： A method for dismantling a furnace having a multilayered refractory structure including: a furnace shell; a containing layer that is formed of a containing refractory that contains asbestos, and covers the inner side of the furnace shell; and a multilayered non-containing layer that is formed of a non-containing refractory that contains no asbestos, and covers the inner side of the containing layer, the method includes: a primary dismantling process; and a secondary dismantling process conducted after the primary dismantling process. In the primary dismantling process, the non-containing layer is dismantled from a furnace-core side thereof but the containing layer and at least one layer of the layers forming the non-containing layer, which is in contact with the containing layer, are left as a remnant. In the secondary dismantling process, the remnant is dismantled while asbestos measures are implemented.

摘要： A hollow shaft of a screw conveyor for transporting powder material receives pressurized air in its interior. A plurality of openings through the wall of the hollow shall permits the pressurized air to exit energetically to prevent build-up of the powder material on the inside wall of the casing of the screw conveyor. In one embodiment, the openings are slits angled with respect to the axis of the screw conveyor at about the same angle as the helical blade. This produces a swirling flow of air which, in addition to preventing build-up of materials, enhances the advance of the powder material and, when the powder material is a mixture of different materials, helps prevent separation of the materials during transport.
