During soot blow, what is the required minimum boiler load and action to avoid fouling the flight deck?

• A. Minimum boiler load 12-15 kts; drive to avoid fouling the flight deck
• B. Minimum boiler load 5-10 kts; stop the operation
• C. Maximum boiler load 20-25 kts; ignore debris
• D. Minimum boiler load 0-5 kts; maintain current course

Answer: (A)

During soot blowing the aim is to use enough steam power and forward motion to push soot and debris away from the flight deck rather than letting it settle on it. A minimum boiler load that supports the soot blowers’ operation is needed, and moving the ship at a moderate speed helps carry any discharged debris off the deck area. The recommended speed range of 12–15 knots provides enough airflow over the flight deck to keep debris from fouling it, while still allowing controlled, safe operation.

If you stop the soot blow or operate at very low speed, the discharged debris isn’t carried clear and can foul the deck, compromising flight operations. Running at maximum boiler load isn’t necessary and can introduce unnecessary risk or wear. So maintaining a suitable boiler load and driving at 12–15 knots is the safest, most effective approach to keep the flight deck free of soot during the blow.
