Welcome to Lecture 4 of Boiler Problems & Softening Methods in Engineering Chemistry (B.Tech 1st Year).

In this lecture, we focus on Boiler Corrosion, one of the most serious problems in steam boilers that directly affects boiler life, safety, and efficiency.

🔹 What You Will Learn in This Lecture:

Introduction to Boiler Corrosion

Meaning of boiler corrosion

How corrosion differs from scaling and sludge

Causes of Boiler Corrosion

Dissolved oxygen in water

Presence of carbon dioxide

Acidic salts and impurities

Electrochemical reactions inside the boiler

Effects of Boiler Corrosion

Damage to boiler metal

Reduction in efficiency

Safety hazards

Prevention of Boiler Corrosion

Mechanical deaeration (removal of dissolved gases)

Chemical methods (oxygen scavengers, alkali treatment, phosphate conditioning)

Proper water softening and treatment

📖 This lecture is part of the Boiler Problems & Softening Methods series in Engineering Chemistry, designed for RGPV and other B.Tech 1st Year students.

✨ After completing this lecture, you will understand:

What boiler corrosion is and why it occurs

Major causes and harmful effects

Industrial and chemical methods of prevention
