In woody biomass or waste to energy plants, high temperature corrosion of boiler tubes, such as active oxidation which is caused by alkali chlorides has become a serious problem. In this study, the active oxidation of metal specimens by NaCl was evaluated with Thermogravimetry - Differential Thermal Analysis (TG-DTA) to elucidate the mechanisms and establish the highly practical solutions for the corrosion. As a result, the active oxidation had a dependency of the metal composition, and there was a correlation between increments of metal specimens with TG isothermal tests and decrements with immersion corrosion tests.
