Web4.1.1 Hematite (α-Fe 2 O 3) Iron is the 4th most abundant element in the Earth's crust and it exists mostly as an oxide because it is easily oxidized in air. Iron has 16 oxides and among these, hematite is the oldest known. Hematite is a red-brown solid that is extremely stable under ambient conditions. WebProper treatment of boiler feedwater effectively protects against corrosion of feedwater heaters, economizers, and deaerators. The ASME Consensus for Industrial Boilers (see Chapter 13) specifies maximum levels of contaminants for corrosion and deposition control in boiler systems. The consensus is that feedwater oxygen, iron, and copper ...
