Question

Draw a neat labelled diagram of a Reverberatory furnace.

Answer 1

Hint: A Reverberatory heater is a heater where rooftop and dividers are warmed by flares and emanate heat onto the material in the focal point of the heater. The term reverberation is utilized here in a generic sense of rebounding or reflecting, not in the acoustic sense of echoing.

Complete answer:
It is utilized for purifying or refining in which fuel isn't in direct contact with metal however warms it by fire blown over it from another chamber. The warmth ignores the hearth wherein mineral is kept and afterward resonates back.
The hearth is made thick and impenetrable so the substantial matte. It is a metallurgical or measures heater that disconnects the material being handled from contact with the fuel, yet not from contact with the burning of gases.

Applications of a Reverberatory furnace are:-
Metallurgical softening heaters
Lower temperature preparing heaters utilized for metallic metals and different minerals.

Additional Information:
A reverberatory heater is a disadvantage from the outlook of productivity contrasted with a shoot heater because of the spatial partition of the burning fuel and the subject material, and it is important to viably use both reflected radiant heat and direct contact with the fumes gases (convection) to expand heat move. These heaters have utilized strong fuel, and bituminous coal has demonstrated to be the most ideal decision. The brightly noticeable flares give a more brilliant warm move than anthracite coal or charcoal.

Note: The possibility to make a mistake is that it is a furnace that isolates the material processing from contact with the fuel, but not from the contact with combustion gases.
