CHIMNEY AND ITS MANUFACTURING METHOD
To provide a chimney which can be manufactured at a low cost by suppressing the weight increase of the whole stack shell and ensuring corrosion resistance.SOLUTION: A chimney 100 for discharging exhaust gas in a gas turbine combined cycle facility comprises: a stack shell lower part 10 provided on a foundation 40 and formed by using a rolled steel material for a welded structure; a stack shell upper part 20 provided on an upper side of the stack shell lower part 10 and formed by using a predetermined low alloy steel material; and a connection part 30 for connecting the stack shell lower part 10 and the stack shell upper part 20.SELECTED DRAWING: Figure 1
【課題】筒身全体の重量化を抑制し、耐腐食性が確保され、低コストで製造可能な煙突を提供する。【解決手段】煙突１００は、ガスタービンコンバインドサイクル設備において排ガスを排出する煙突１００であって、基礎４０上に設けられ、溶接構造用圧延鋼材を用いて形成される筒身下部１０と、筒身下部１０の上側に設けられ、所定の低合金鋼材を用いて形成される筒身上部２０と、筒身下部１０と筒身上部２０とを接続する接続部３０とを備える。【選択図】図１
