How can the efficiency of a joint primarily be affected in modern boiler design?

In modern boiler design, the efficiency of a joint can be significantly affected by using welded joints. Welding creates a continuous and strong bond between the components, which allows for better integrity under high pressure and temperature conditions typical in boiler operations. This process results in a seamless connection that minimizes the likelihood of leaks and potential failure points, thereby enhancing the overall efficiency and reliability of the boiler system.

Welded joints also tend to reduce the weight of the structure compared to riveted or bolted joints, which can lead to improved heat transfer and, consequently, better thermal efficiency. Additionally, welded joints can be designed to match the materials and thicknesses of the components being joined, which can further optimize performance and lifespan.

In contrast, riveted, bolted, and glued joints may not provide the same level of efficiency or strength under the specific demands encountered in boiler applications, leading to potential risks such as leaks or failures that could negatively impact the system's performance.
