Which of the following actions should be carried out if the boiler water level is falling due to a tube failure?
AI Explanation
The correct answer is D) Secure the fires and try to maintain the water level.
When a boiler tube fails, it can cause a rapid loss of boiler water level. In this situation, the safest course of action is to secure the fires and focus on maintaining the remaining water level, rather than trying to increase the feed rate. Increasing the feed rate could actually worsen the situation by causing thermal shock to the boiler, potentially leading to further damage.
The other options are incorrect because they involve continuing to fire the boiler or adding additional feed, which could make the situation more hazardous. The priority should be preserving the integrity of the boiler by securing the fires and conserving the remaining water level until the tube failure can be addressed.
