Furnace Explosions: Causes and Prevention

What can cause furnace explosions?

a) Accumulation of fuel

b) Faulty electrical wiring

Answer:

The correct answer is: a) Accumulation of fuel

Furnace explosions can indeed be caused by an accumulation of unburnt fuel in the furnace, which can form combustible gases. These gases, when exposed to a spark or flame, can cause an explosion. Regular maintenance and proper operation of a furnace are therefore crucial for safety.

Explanation:

The statement 'Furnace explosions are caused by an accumulation of fuel in the furnace' is true. Furnaces operate by burning fuel to produce heat. If there is an excess of fuel in the furnace that is not burnt off, it can lead to an accumulation of combustible gases. If this gas comes into contact with a spark or flame, an explosion can occur. This situation is particularly dangerous because it can lead to substantial damage and potential harm. To ensure safety, it is necessary to maintain furnaces regularly and make sure that they are operated appropriately.
