What is the main function of a stay bolt in a boiler?

The main function of a stay bolt in a boiler is to support the boiler structure. Stay bolts are essential components used to maintain the integrity and stability of the boiler. They help resist the internal pressures and forces exerted on the boiler shell and other parts during operation. By providing additional strength, stay bolts prevent distortion and bulging of the boiler, especially in areas where high temperatures and pressure are present.

This support is critical because a properly supported boiler can operate safely and efficiently. If the structure were to become unstable or distorted, it could lead to leaks, inefficiencies, or even catastrophic failure.
