Which of the following is a directly fired intermittent furnace ?
Correct answer: A. Reverberatory furnace
- A. Reverberatory furnace
- B. Walking beam reheating furnace
- C. Tower furnace
- D. Tunnel kiln
Explanation
A reverberatory furnace is directly fired because combustion gases transfer heat directly to the charge, usually by radiation from the flame and hot roof. Walking-beam and tunnel furnaces are generally continuous rather than intermittent furnace types.
