Zusammenfassung: | To provide the stable continued operation of a coke oven by applying a constant oven fastening force to the whole end face in the oven length direction of a coke oven, especially a combustion chamber, and by suppressing expansion of the combustion chamber, retaining durability of the combustion chamber, and extending the oven life of the coke oven in an environment with a high thermal load for a long time.SOLUTION: There is provided an oven fastening structure of a chamber-type coke oven for applying an oven fastening force in the oven length direction of a coke oven by a back stay arranged at both ends in the oven length direction of the coke oven, the coke oven having carbonization chambers for holding coal to be carbonized and combustion chambers for burning fuel gas that are alternately arranged. The back stay is configured such that both ends of the back stay for oven fastening having a bow shape are oven-fastened to end faces of the coke oven.SELECTED DRAWING: Figure 1(a)
【課題】コークス炉、特に燃焼室の炉長方向端面の全体に常時一定の炉締力を付与して維持することができ、長期間熱的な負荷の高い環境において、燃焼室の膨張を抑制し、燃焼室の堅牢性を保持し、コークス炉の炉寿命を伸ばし、コークス炉の運転を安定的に継続できるようにする。【解決手段】乾留させる石炭を入れるための炭化室と、燃料ガスを燃焼させるための燃焼室とを交互に複数配列されたコークス炉を、このコークス炉の炉長方向の両端部に配置されたバックステーによって、コークス炉の炉長方向に炉締力を付与する室炉式コークス炉の炉締め構造であって、バックステーは弓状形状を有する炉締め用バックステーの両端部が前記コークス炉の端面に炉締めされたものである。【選択図】図1(a) |
