Furnace design and operating practices, including furnace size and shape, and burner design and location, strongly influence the performance of aluminum smelters.
Side-Well Reverberatory Furnaces
Reverberatory furnaces are widely used for melting aluminum in both primary and secondary facilities. A typical side-well reverberatory furnace consists of a number of burners firing inside the hearth, against the furnace hot wall or door. A charging well and a pump well, when present, are attached to the furnace hot wall on the outside of the furnace. Both wells are connected to each other and with the furnace hearth by arches, which permit aluminum circulation between the furnace chambers.
