The support is a structural component within the indirect air heater assembly, responsible for holding key internal parts in their correct operating position. By maintaining proper alignment and spacing, it ensures the heater functions efficiently and that connected components are not subjected to undue stress or movement during operation. When a support becomes cracked, bent, or fatigued, it can compromise the stability of the assembly, leading to vibration, misalignment, or premature failure of adjacent components.
