Some ash particles in municipal and industrial waste adhere to heat exchanger tube surfaces, which causes problems such as heat-transfer inhibition, high temperature corrosion and low utilization in Waste-to-Energy (WtE) plants. The objective of this study is to develop new surface treatment materials and techniques which can decrease the ash deposition and corrosion. In this paper, the effects of the new material developed were verified on site. The results of the test show that the new material decreased ash deposition and high-temperature corrosion due to molten salts compared to SUS310S.
