Description

Technical Field

[0001] The invention relates to the technical field of reverberatory furnace waste heat recovery, in particular to a reverberatory furnace flue gas heat exchange device. Background Art

[0002] A reverberatory furnace is a chamber-type flame furnace. Heat transfer within the furnace relies not only on the reflection of the flame but, more importantly, on radiation from the furnace roof, walls, and hot gases. Many furnace types (such as heating furnaces and open-hearth furnaces) can be classified as reverberatory furnaces based on their heat transfer mechanism. These furnaces are generally used for nonferrous metal smelting.

[0003] A reverberatory furnace, also known as a flame reverberatory furnace, is a metallurgical furnace that uses flames to directly heat materials and melt metals. It consists of three main parts: a combustion chamber, a smelting chamber, and an exhaust flue (chimney). The entire furnace is a rectangular smelting chamber lined with refractory material. Reverberatory furnaces offer a simple structure, low investment, and the ability to accept a wide variety of fuels (such as coal, gas, and heavy oil). They are essential equipment for smelting non-ferrous metals such as copper, nickel, and tin. They are widely used to process ores and concentrates, especially fine-grained powders. They can also smelt ferroalloys and are used in fire refining of metals. However, direct flame contact with the metal results in significant oxidation losses. Reverberatory furnaces are commonly used as roasting equipment in the metallurgical and chemical industries.

[0004] However, the existing reverberatory furnace waste heat recovery devices are relatively bulky, difficult to assemble, require a lot of manpower, have low efficiency, and do not filter and reduce dust on the flue gas of the waste heat, so the waste heat has a limited application range and cannot be directly discharged outdoors. There is no insulation device for the reverberatory furnace waste heat, resulting in a large amount of heat loss and poor economic efficiency. Summary of the Invention
