What is the role of braces in a boiler design?

In boiler design, braces serve a structural purpose by providing necessary support to various components. Specifically, they aid in supporting surfaces that do not contain tubes and help prevent bulging, which can occur due to the internal pressures and temperatures experienced within the boiler. This structural integrity is vital for the safe and efficient operation of the boiler, ensuring that components can withstand the stresses involved without deforming. By preventing bulging, braces help maintain the correct alignment and functioning of the boiler, contributing to its overall reliability and safety.
