検時間が短縮される。According to the present invention, when replacing a panel in the HRSG, there is no need to remove extra equipment such as equipment and facilities including piping around the HRSG prior to removing the panel, thereby reducing the restoration range. Therefore, both the amount of work and the process are reduced, and the repair cost can be reduced. In addition, by arranging the equipment and facilities usually arranged on both sides of the casing on one side, the physical quantity of facilities such as pipes, cables, floors, walkways, etc. is reduced, resulting in an economical design. With the centralized arrangement of equipment and facilities,
The distance of the corridor at the time of the operator's inspection is also reduced, and the time required for the operator's daily inspection is reduced.
