Tower Furnace

Southern Thermal Engineering Company offers a Tower Furnace. Tower furnaces are loaded from the top of a vertical tower with aluminium, and burners at the bottom of the tower melt the aluminium. The primary mode of heat transfer in tower furnaces is through convection by direct impingement of the burner on the metal in the lower section of the tower, and by the combustion gases as they travel out the tower past the metal charge. A variation of the tower furnace uses a grate system which lowers the metal through four grates, gradually heating the charge through each grate until on the fourth and final grate, the charge melts and falls into the hearth. The advantages of the tower furnaces are high efficiency (40%-77%) and low oxidation losses. The disadvantages of tower furnaces are their high capital costs and the furnace size is restricted by height limitations. The Ecomelt Electro-Mech Tilting (EMT) tower furnace is used for the following applications: central melting in die casting; ingot manufacturing; alloy making; metal recycling; and bulk melting. General performance specifications: fuel consumption – 60 ltr/tonne at 720°C; metal loss – 1.6% to 2%; capacity – 300 kg/hr to 4 tonne/hr; loading – by auto charger; and fuel – LDO/FO/HSD/LPG/propane. Ecomelt-EMT consists of: a stationary melting chamber; electromechanical tilting holding chamber connected to melting chamber by a tunnel; and auto charger. Advantages: minimum oil consumption (as low as 52 ltr/tonne is recorded with fuel LDO); low melting losses (as low as 1 % is recorded); low risk of hydrogen absorption; easy wall to wall access for through cleaning; minimum manpower requirement; low operating cost; continuous supply of molten metal; and capacity range – 300 kg/hr to 4000 kg/hr. The high degree of automation, quality of the materials and simple construction of the equipment guarantees a reliable and efficient production with high degree of economy resulting in profitable production of molten metal. Southern Thermal Engineering Company is one of the leading manufacturers, exporters and suppliers of a wide variety of thermoplastic and pollution control systems. The product range includes pickling tanks, pickling plants, fume extraction systems and chemical storage tanks, etc.
