Which statement regarding the firing of a boiler is true?

The fire should always be on when the boiler is full of water
A fire can be absent without consequences in a cold boiler
Fuel should not be added without water in the boiler
Both A and B are correct

The correct answer is: Fuel should not be added without water in the boiler

The statement that fuel should not be added without water in the boiler is true because having water in the boiler is essential for safe operation. When a boiler is fired without water, it can lead to overheating and damage to the boiler components, potentially resulting in catastrophic failure or explosion. The presence of water is crucial because it absorbs the heat generated by the fire, preventing metal from reaching dangerous temperatures. On the other hand, the idea that the fire should always be on when the boiler is full of water (the first point) might not be universally true, as there are situations in which a boiler may need to be shut off safely due to maintenance or other operational needs. Likewise, a cold boiler may be safely without fire while it is being prepared for startup or maintenance (the second point). Therefore, while fuel should always have water in the boiler before firing, the other statements do not universally uphold the requirements for safe operation.
