What is the primary function of the boiler sliding feet?

• A. To secure the boiler to the foundation
• B. To allow for expansion and contraction of the boiler
• C. To improve the efficiency of heat transfer
• D. To facilitate maintenance access

Answer: (B)

The primary function of the boiler sliding feet is to allow for expansion and contraction of the boiler. Boilers operate at high temperatures and pressures, which cause the materials they are constructed from to expand when heated and contract when cooled. The sliding feet are specifically designed to accommodate this movement, enabling the boiler to adjust to these changes without causing damage or stress to the overall structure. If the boiler were rigidly fixed to its foundation without any means of accommodating movement, it could lead to alignment issues, increased wear and tear, and potential failure of the boiler components. By allowing the boiler to expand and contract naturally, sliding feet play a crucial role in the longevity and safe operation of the boiler system, ensuring that it can function effectively under varying thermal conditions. The other options focus on aspects that are either indirectly related or not the primary purpose of the sliding feet. For example, securing the boiler to the foundation and improving heat transfer efficiency are important aspects of boiler design but are not directly related to the specific role of the sliding feet. Facilitating maintenance access, while a practical consideration, is not the function of the sliding feet themselves.
