The Role of Fireside Corrosion on Boiler Tube Failures, Part I

Furnace Corrosion Fundamentals. Fireside corrosion in the superheaters and reheaters of coal-fired units is known as coal ash corrosion, in oil-fired units as oil ash corrosion, and in refuse-fired boilers as ash corrosion. Sometimes, fireside corrosion is also referred to as hot corrosion. The mechanism in each case is similar,
