🔍 Key Concepts

• Soot blower operation – how steam is directed through the lance element during rotation and retraction • Cam‑actuated valve function – what a cam does mechanically as it rotates with a shaft • Safety interlock ideas – how systems protect equipment if a moving part stops unexpectedly

💭 Think About

• Think about what happens if the soot blower element STOPS rotating while steam is still flowing through the nozzle holes—what could that do to the tubes or refractory? • Consider what a rotating cam is especially good at doing: does it mainly set angle of rotation, control sequence, or act like an on/off interlock tied to motion? • Which answer choice describes a function that depends directly on whether the element is MOVING or NOT moving, rather than on timing or positioning alone?

✅ Before You Answer

• Check which option clearly describes a motion‑dependent safety function rather than a timing or sequencing function. • Eliminate any choice that could be done instead by electrical or timer-based controls without needing a mechanical cam linked to the rotating element. • Ask yourself: which function would be most critical to prevent localized overheating or damage if the element stopped turning?
