Question 1 of 27070

Q

Coast Guard Regulations (46 CFR) specify that the fuel oil ignition system, on a small automatically fired auxiliary boiler, shall be energized __________.

🔍 Key Concepts

• 46 CFR requirements for automatically fired auxiliary boilers on small vessels • Required sequence of operations for safe boiler startup (purge, fuel, ignition, flame proving) • The purpose of a trial for ignition period and how it relates to energizing the ignition system and opening the fuel oil valve

💭 Think About

• Think through the safest logical order: Should ignition happen before, after, or at the same time as admitting fuel to the furnace? Why? • What is the difference between a prepurge period and a trial for ignition period in automatic boiler controls? • Which answer choice most closely matches the typical control sequence used to prevent accumulation of unburned fuel in the furnace?

✅ Before You Answer

• Verify in 46 CFR Part 63 – Automatic Auxiliary Boilers for the defined startup sequence. • Check which step comes immediately before the trial for ignition period in the regulatory language. • Confirm whether the regulation links energizing the ignition system to the fuel oil valve position or to a specific timed period (like prepurge or trial for ignition).
