Zusammenfassung: | To provide a water filling method for a bundle that improves workability in repair work for heat transfer tubes.SOLUTION: In a heat exchanger, a bundle in which one end part in a longitudinal direction in a plurality of heat transfer tubes arranged along a vertical direction is connected to an inlet header arranged along a horizontal direction, and the other end part in the longitudinal direction is connected to an outlet header arranged along the horizontal direction is arranged in an exhaust gas passage of a duct casing. A water filling method for the bundle comprises a step of supplying a heat medium to the plurality of heat transfer tubes through the inlet header or the outlet header, and a step of supplying the heat medium to the heat transfer tubes in which the supply of the heat medium is insufficient, out of the plurality of the heat transfer tubes from work holes of the inlet header or the outlet header opposed to connection parts of the heat transfer tubes.SELECTED DRAWING: Figure 1
【課題】バンドルの水張方法において、伝熱管の補修作業における作業性の向上を図る。【解決手段】鉛直方向に沿って配置される複数の伝熱管における長手方向の一端部が水平方向に沿って配置される入口ヘッダに連結されると共に長手方向の他端部が水平方向に沿って配置される出口ヘッダに連結されるバンドルが、ダクトケーシングの排ガス通路に配置される熱交換器において、前記入口ヘッダまたは前記出口ヘッダを通して前記複数の伝熱管に熱媒体を供給する工程と、前記複数の伝熱管のうちの前記熱媒体が供給不足である前記伝熱管に対して、前記伝熱管の連結部に対向する前記入口ヘッダまたは前記出口ヘッダの作業孔から熱媒体を供給する工程と、を有する。【選択図】図1 |
