LCA (Life cycle assessment) is a systematic process used to calculate and evaluate the environmental impacts of products. Because boiler components are now exposed a more severe erosion/corrosion environment by improving efficiency of thermal power plant, it is expected that the use of thermal spray coatings will increase.
The LCA method was attempted to apply to various thermal spray coatings for PFBC (Pressurized Fluidized Bed Combustion) and evaluate the eco-friendly coatings. The result was gained that all the alumina coatings have good characteristics. In fact the Al2O3-40%ZrO2 coating by APS has the lowest environmental impact and the best erosion resistance, it may be considered the most effective coating.
