what is the difference between reverberotory furnace and blastfurnace?
Reverberatory furnace used for smelting, refining, or melting in which the fuel is not in direct contact with the contents but heats it by a flame blown over it from another chamber. Such furnaces are used in copper, tin, and nickel production.
A blast furnace is a type of metallurgicalfurnace used for smelting to produce industrial metals, generally iron.In a blast furnace, fuel and ore are continuously supplied through the top of the furnace, while air (sometimes with oxygen (enrichment) is blown into the bottom of the chamber, so that the chemical reactions take place throughout the furnace as the material moves downward. The end products are usually molten metal and slag phases tapped from the bottom, and flue gases exiting from the top of the furnace.
