Abstract
The metal materials corrosion in the boiler steam-water system influences the safe and economic operation of the boiler system. In this work, the corrosion experiment of carbon steel is carried out in the high-temperature autoclave to simulate the boiler steam-water system. The effect of temperature and dissolved oxygen on the corrosion of carbon steel is studied by the corrosion weight loss rate, surface changes and micro-morphology characterization. At 120~150°C, the carbon steel mainly dissolves in pure water and many corrosion spots are formed on the surface of corroded samples. At 200~300°C, the carbon steel is mainly oxidized in pure water and the corrosion spots are less; especially at 350°C, the surface of corroded carbon steel is covered with black ash material and there is almost no corrosion spot. The content of dissolved oxygen in pure water affects carbon steel’s corrosion. The content of dissolved oxygen in pure water should be controlled as low as possible to reduce the corrosion of carbon steel.
