For the stable supply of electricity, the boiler of large-sized coal-fired power plants are being operated in very poor conditions such as continuous operation in high temperature and high pressure condition or repeating of start-up and shutdown. So, it is essentially required to perform periodic inspection and maintenance on them to secure their reliability. In particular, a lot of works are performed in the boiler furnace during preventive maintenance period to prevent the problems expected in the operation, and the most important consideration for this time is the securing of safety for the workers to pursue effective workability. Existing scaffolding systems are assembled in stacking up manner with base foundation in the lower ground, which causes the load concentration in the lower part. So, if there are some problems in the members, the scaffolding system will eventually collapse. So, in this study, safe furnace scaffolding system is to be developed by dispersing the load in the upper part, as well as minimizing the hazard of serial collapsing. Also, for the cases where direct installation of wire-rope type furnace scaffolding is challenging due to the structure of the boiler tube, the lifting system for the installation of furnace scaffolding is to be developed so that the wire-rope type furnace scaffolding can be supported to secure the integrity of the power generating facilities. The scaffolding system to be developed in this study allows partial disassembling and installation while maintaining safety for even the interfered parts when maintaining and replacing the large-sized components such as the tube panel and water wall by the benefit of the characteristics of the upper-supporting system which contributes to the time saving and easy maintenance of the workers. The design on the scaffolding system for this study was performed by comparing and analyzing the steel-frame structures of the boiler upper part and inner tube structures with their drawings. Also, stress analysis, structural analysis as a complete assembly, performance for the members, and mock-up test were performed simultaneously to secure safety, as well as apply the scaffolding system to 500㎿ supercritical coal-fired power plants successfully.
