  • Low Temperature Corrosion in Boiler and Its Prevention

    Fuels used in boilers contain different levels of sulphur which is the primary cause for cold end corrosion. The severity depends on many factors like percentage of sulphur in fuel, excess air, moisture in flue gas etc. There are many methods used world over to contain cold end corrosion. These methods fall in the category of in combustion reduction and post combustion reduction.
