PROBLEM TO BE SOLVED: To dismantle a coke oven and reconstruct a coke oven more improved in productivity compared to that before dismantlement.SOLUTION: A reconstruction method of a chamber type coke oven, in which a regenerative chamber is disposed on a hearth structure, and a carbonization chamber and a combustion chamber are alternately disposed thereon, comprises (x) dismantling the carbonization chamber, combustion chamber and regenerative chamber, while leaving the hearth structure; (y) constructing a regenerative chamber with the same height as that before dismantlement on the hearth structure; and (z) constructing a carbonization chamber and a combustion chamber on the regenerative chamber by (z1) making the height of oven equal to that before dismantlement, and (z2) making the kiln core pitch ((carbonization chamber width)+(combustion chamber width)) larger than the kiln core pitch before dismantlement. |
