<p>A method for dismantling a furnace having a multilayered refractory structure including: a furnace shell (61); a containing layer (62A) that is formed of a containing refractory (621, 622) that contains asbestos, and covers the inner side of the furnace shell; and a multilayered non-containing layer (62B) that is formed of a non-containing refractory (623 to 625) 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 (62B) is dismantled from a furnace-core side thereof but the containing layer (62A) and at least one layer (623) of the layers forming the non-containing laxer (62B), which is in contact with the containing layer, are left as a remnant (62C). In the secondary dismantling process, the remnant (62C) is dismantled while asbestos measures are implemented.</p> |
