PROBLEM TO BE SOLVED: To safely and surely demolish an inner cylinder built by layering a refractory brick for partitioning a flue in a chimney in chimney demolishing work of a waste incinerating facility.
SOLUTION: This chimney inner cylinder demolishing device has a support body 11 suspended/held in an outer cylinder space substantially coaxially with the plane cross-sectional center of the outer cylinder space of the chimney 1, a support jack 20 installed on the support body 11 and positionally holding the support body 11 in the outer cylinder space by pressing an outer cylinder wall surface 1d by the tip, a turning driving part housed in a body part continuously arranged on the support body and having a rotary shaft coaxially rotatable with the axis of the support body 11 and a crushing jack having a crushing pick movable by the extension-contraction of a rod in the direction orthogonal to the rotary shaft held via a slide jack 30 having the body part fixed to the rotary shaft end of the turning driving part. A seam of the brick of an inner cylinder 2 is crushed by performing reciprocating pressing operation to the inner cylinder 2 of the crushing pick.
