Which risk increases when a resonant frequency overlaps excitation functions in a boiler?

💡 Explanation

Harmonic amplification fatigue increases because resonant frequencies matching pump excitation functions initiate constructive wave interference, causing amplified vibrations therefore materials experience cyclic stress beyond design rather than alternative heat effects.
