Abstract
The utility model relates to a rotation cover manhole mechanism of a flame-tube type waste heat boiler. The rotation cover manhole mechanism of the flame-tube type waste heat boiler comprises a smoke box body. A heat-resistant layer is arranged on the inner wall of the smoke box body. A rotation cover manhole is connected on the tail portion of the smoke box body in an inserting mode. A fireproofing tile ring layer is arranged on the inner wall of the rotation cover manhole. A fireproofing fibrofelt layer is connected with the fireproofing tile ring layer. The fireproofing fibrofelt layer is located on the tail portion of the rotation cover manhole. The rotation cover manhole mechanism of the flame-tube type waste heat boiler is simple in structure and good in using effect.
