In the event of a flame failure in an auxiliary water-tube boiler, you must _______________.
AI Explanation
The correct answer is C) purge the furnace of any combustible gases before attempting to relight the fire.
In the event of a flame failure in an auxiliary water-tube boiler, it is crucial to purge the furnace of any combustible gases before relighting the fire. This is to prevent the risk of a sudden flare-up or explosion when the fire is relit, which could be hazardous. The other options, such as relighting the boiler immediately or relighting off the brickwork, would be unsafe and could lead to further damage or injury. Speeding up the feed pump (option D) would not address the immediate safety concern of the combustible gases in the furnace.
