essay on reverbaratory furnace
Answers
furnace in which the roof and walls are heated by flames and radiate heat on to material in the centre of the furnace.
A reverberatory furnace is a metallurgical or process furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. The term reverberation is used here in a generic sense of rebounding or reflecting, not in the acoustic sense of echoing.
process furnace that isolates the material being processed from contact with the fuel, but not from contact with combustion gases. A furnace or kiln in which the material under treatment is heated indirectly by means of a flame deflected downward from the roof. Reverberatory furnaces are used in a copper, tin, and nickel production, in the production of certain concretes and cements, and in aluminum. Reverberatory furnace heat the metal to melting temperatures with direct-fired wall-mounted burners. The primary mode of heat transfer is through radiation from the refractory brick walls to the metal, but convective heat transfer also provides additional heating from the burner to the metal. The basic advantage of a reveb/skelnar furnace is the ease of operation and relatively low maintenance cost. It also has a low capital investment cost. The disadvantages would be high oxidation losses due to the large surface area exposed to a direct flame and also higher fuel consumption compared to a shaft furnace.
