Heat storage reflective furnace is the core energy-saving equipment for industrial non-ferrous metal smelting. With the unique principle of waste heat recovery and utilization, it surpasses traditional old-fashioned reflector furnaces and is widely used in the fields of aluminum, copper, zinc alloy smelting and waste metal recycling. To understand the Heat storage reflective furnace, it is necessary to first clarify its core differences from traditional reflectors. The traditional reflector furnace has a simple structure and relies on flames to directly heat materials. The high-temperature flue gas generated by melting is directly discharged from the flue, and a large amount of heat energy is lost in vain. This not only consumes a lot of energy, but also easily causes problems such as high temperature in the workshop and excessive exhaust gas. The biggest innovation of the regenerative reflector furnace is the addition of a regenerative heat exchange system, which enables the recovery and reuse of waste heat from flue gas, which is also the core key to its energy conservation.
The Heat storage reflective furnace is mainly composed of a melting furnace, a heat storage chamber, a ceramic heat storage body, a reversing valve, and a smoke exhaust and air supply system. The entire equipment forms a closed-loop heat exchange system. Its core working principle is divided into two alternating cycles, fully automated operation, without frequent manual intervention, suitable for continuous smelting production in factories.
The first stage is the heat storage and absorption stage. During the combustion operation of the equipment, the high-temperature flue gas generated in the furnace will flow into the heat storage chamber on one side along the flue, and the heat in the flue gas will be fully absorbed and stored by the dense ceramic heat storage body inside. At this point, the other channel is closed, and the heat from the smoke is firmly retained without direct leakage, effectively locking in excess heat energy and avoiding heat waste.
The second stage is the preheating and heat exchange stage. After the thermal storage body is fully stored, the intelligent directional valve of the equipment automatically switches channels. The ambient temperature air and fuel from the outside will first flow through the high-temperature heat storage body, be preheated to several hundred degrees Celsius, and then be sent into the furnace for combustion and melting. The preheated medium burns more fully, the furnace heats up faster and the temperature is more uniform, greatly improving the utilization rate of heat energy.
Two stages are continuously alternated through a directional valve to maintain the efficient operation of the Heat storage reflective furnace in a "heat absorption release" state. This cycle mode completely changes the drawbacks of traditional furnace one-way exhaust and heat waste, greatly improving the recovery rate of flue gas waste heat and achieving a comprehensive energy saving rate of over 30%, effectively reducing the production cost of enterprise smelting. In addition, the reflection heating principle of the thermal storage reflector furnace is also crucial. The inner wall of the furnace is made of specialized refractory reflective material, which can fully reflect and focus the flame and high-temperature heat radiation onto the surface of the material, avoiding heat loss and ensuring uniform heating of the material. This not only increases the melting efficiency but also reduces metal oxidation, improving the quality of the melted product.
