Types of Boilers

1. Fire-Tube Boilers

• Description: Hot gases from combustion pass through tubes surrounded by water.
• Advantages: Compact design, easy to operate, and relatively low cost.
• Applications: Small to medium industrial plants. Heating buildings (e.g., schools, hospitals). Steam locomotive engines.

2. Water-Tube Boilers

• Description: Water flows through tubes heated by combustion gases.
• Advantages: High-pressure and high-temperature capability, suitable for large steam demands.
• Applications: Power generation in thermal power plants. Industrial process heating. Marine applications.
