According to 46 CFR regulations pertaining to periodic tests and inspections as related to automatic auxiliary boilers, flame safeguard controls must be checked for proper shutdown operation. Which of the following must be checked? 1) Flame failure. 2) Ignition failure. 3) Audible alarm of shutdown. 4) Visual indication of shutdown. 5) Shutdown times.
• 46 CFR Part 61 – Periodic tests and inspections for boilers and machinery • Purpose of flame safeguard controls on automatic auxiliary boilers • Difference between failure conditions (what can go wrong) and indications/alarms and timing (how the system alerts and reacts)
• If the Coast Guard wants to be sure a flame safeguard system is working correctly, what types of failures must it safely respond to? • Besides detecting a problem, what must be verified so that the operator is clearly warned and the boiler is protected? • Would timing of shutdown be part of proving the safeguard is effective, or is that outside the scope of a safeguard test?
• Look in 46 CFR under boiler periodic tests and inspections for the exact list tied to 'flame safeguard controls'. • Check whether both failure conditions (like flame and ignition) and alarm/indication functions are explicitly mentioned together. • Verify whether shutdown times are specifically required to be checked as part of the flame safeguard test, not just general boiler tests.
