摘要
Abstract
Water molecules under ultra-supercritical conditions have strong oxidizing nature, which makes boiler water wall tubes form dense scale. Based on the analysis of the scale composition for the two 600-MW ultra-supercritical units at one power plant, the static and dynamic simulation tests are conducted with three sorts of organic acids. And the corrosion rate and corrosion quantity of the metal piece are determined respectively. Following the dynamic simulation test result, 2% glycolic acid and 0.5% sodium fluoride with a certain amount of inhibitor is chosen as the cleaning agent for the two units. After cleaning, both the corrosion rate and corrosion quantity meet the related standard, which indicates that the cleaning effect is satisfactory.关键词
