How long must the atomizer barrel be cooled after removal from the burner assembly before disassembly?

The correct answer is based on safety protocols and practices when working with equipment that has undergone high temperatures, such as an atomizer barrel from a burner assembly. The cooling period is important to ensure that any residual heat dissipates, reducing the risk of burns or equipment damage during disassembly.

Cooling the atomizer barrel for 15 minutes allows sufficient time for the components to reach a safer, more manageable temperature. This timeframe is typically based on industry standards that take into account the material properties and the operational temperatures the component must withstand.

Longer cooling times are often recommended to ensure thorough cooling, while shorter times may not adequately protect personnel or equipment. Therefore, while options suggesting a cooling time of 5, 10, or 20 minutes may seem practical, the 15-minute mark strikes an appropriate balance between safety and efficiency.
