🔍 Key Concepts

• Boiler steam drum vs water (mud) drum functions in a typical marine boiler • What conditions must be stable and adequate before assuming an engine room/fire room watch • Which parameter most directly affects safe, continuous flame at the boiler burners

💭 Think About

• Think about what you must be absolutely sure of to keep the boiler flame safely burning as soon as you take the watch. • Consider which of these options would cause an immediate problem for the boiler if it were incorrect: which one would most directly affect combustion? • Ask yourself which parameters are normally monitored together on a boiler log at the moment of watch relief.

✅ Before You Answer

• Verify which drum level is already being checked in the question: steam drum or water (mud) drum. • Identify which of the remaining options relates directly to fuel/combustion supply to the burners, not just general machinery health. • Consider standard boiler watch-standing practice: what pair of readings are usually checked together right away for safe firing?
