In reverberatory furnace, charge is heated mainly by__________________?
Correct answer: B. Radiation of heat from the roof of the combustion chamber
- A. Conduction
- B. Radiation of heat from the roof of the combustion chamber
- C. Natural convection
- D. None of these
Explanation
In a reverberatory furnace, the flame and hot gases heat the roof, which then radiates heat onto the charge. Radiation is therefore the main heating mode, rather than direct conduction or natural convection.
