1. Boiler Structure Presentation Overview of Structural Arrangement, Loads, and Design Considerations

2. Introduction • Boilers are critical components in power plants and industrial facilities. • The boiler structure supports the pressure parts, auxiliaries, and platforms. • Proper structural design ensures safety, stability, and operational reliability.

3. Types of Boilers • Fire-tube Boilers • Water-tube Boilers • Utility / Power Plant Boilers • Package Boilers Structural requirements vary with type and scale.

4. Boiler Structure Overview • Main Columns and Beams • Bracing System • Buckstays (for furnace walls) • Platforms and Walkways • Foundation and Anchor Bolts

5. Loads on Boiler Structure • Dead Load – Self weight of structure and equipment • Live Load – Maintenance, access, piping, platforms • Wind Load – Lateral stability • Seismic Load – Earthquake considerations • Thermal Loads – Expansion and contraction • Equipment Load – Pressure parts, auxiliaries

6. Design Codes & Standards • ASME Boiler and Pressure Vessel Code • IS 875 (Loading Standards) • IS 1893 (Seismic Design) • AISC / IS 800 (Steel Structure Design) • Project-specific specifications

7. Key Structural Components • Columns – Primary vertical supports • Beams – Carry platforms, loads, and transfer forces • Bracing – For lateral stability • Buckstays – Prevent boiler wall buckling • Foundations – Transfer loads safely to ground

8. Platforms & Access • Maintenance platforms around pressure parts • Ladders and staircases for access • Handrails for safety • Monorail beams for material handling

9. Thermal Expansion Considerations • Boilers undergo large thermal movements • Support system must allow expansion • Sliding and fixed supports used strategically • Prevents excessive stresses in pressure parts and structure

10. Construction & Erection Sequence • Foundation and anchor bolts • Erection of main columns • Beams and bracing installation • Boiler pressure parts lifted into place • Platforms, staircases, and auxiliaries • Alignment and final welding

11. Safety Considerations • Adequate access for inspection and maintenance • Fire protection and escape routes • Compliance with occupational safety standards • Proper welding, bolting, and quality checks

12. Case Example (Project Specific) • Example boiler structure layout • Column and beam arrangement • Buckstay and bracing system • Image/diagram to be inserted here

13. Conclusion • Boiler structures are vital for supporting heavy loads. • Must withstand wind, seismic, and thermal effects. • Safe design ensures reliability and long service life. • Proper codes and standards must be followed.
