Question

Gas-Fired burner is used in which of the following furnace?

(a) Induction Furnace

(b) Reverberatory Furnace

(c) Cupola Furnace

(d) Crucible Furnace

The question was posed to me in an online interview.

Answer 1

The correct answer is:

(b) Reverberatory Furnace

A gas-fired burner is typically used in a reverberatory furnace. This type of furnace uses gas burners to heat the material by radiating heat off the furnace roof and walls, which then "reverberates" down onto the material. The use of gas-fired burners makes it more energy-efficient and easier to control compared to other fuels like coal or oil.

In contrast:

• Induction furnaces use electromagnetic induction to heat the material.
• Cupola furnaces generally use coke and a blast of air to melt metals.
• Crucible furnaces are usually heated by electric resistance or other direct heating methods, not typically gas-fired burners.

So, gas-fired burners are commonly associated with reverberatory furnaces.
