Energy saving measures for industrial kilns

When designing or improving industrial kilns, new energy-saving furnaces should be selected as much as possible according to the production process requirements. Choose an appropriate furnace structure to improve mechanization and energy utilization. Commonly used energy-saving measures include using a circular furnace instead of a box-shaped furnace, which can enhance the uniform heat transfer effect of the furnace to the workpiece, reduce the heat dissipation of the furnace wall, and form a heat exchange system in the furnace, among the heating elements, furnace lining and Heat exchange between workpieces. By using a reasonable furnace space and increasing the furnace inner wall area without increasing the furnace space volume, the furnace heat exchange is increased by increasing the heat exchange area, thereby improving thermal efficiency.
Install a fan in the furnace to enhance convection heat transfer in the furnace. Especially for small heating furnaces, the high-speed air flow can destroy the bottom layer of the furnace gas boundary that is stagnant on the workpiece surface and hinders heat transfer and interface reaction, shortening the heating time and accelerating the increase in the temperature of the workpiece.
Industrial kiln furnace body sealing, including sealing of each lead-out component in the furnace, furnace shell, furnace door, etc. If the furnace body is not sealed tightly, it will cause fire and leakage everywhere, resulting in a large amount of waste of energy, equipment burnout, bad environment, etc. Therefore, the sealing of the furnace body directly affects the quality of the workpiece and energy consumption. At the same time, sealing is also an important factor in controlling the atmosphere in the furnace. The essential. The emergence of refractory fiber products has created conditions for furnace body sealing and achieved soft sealing.
Heating furnaces cast integrally with refractory castables have the advantages of high strength, integrity, good air tightness, and long service life.
Adopt new furnace materials and optimize the furnace lining structure. On the premise of ensuring the structural strength and heat resistance of industrial kilns, the furnace lining should maximize its thermal insulation capacity and reduce heat storage. Simply relying on increasing the thickness of the furnace lining to reduce the temperature of the furnace outer wall will not only increase the heat storage and cost of the furnace lining, but also correspondingly reduce the effective utilization of the furnace bottom area. Use refractory fiber, rock wool, etc. as the insulation layer, and use lightweight bricks as the lining of the furnace body to reduce the heat storage loss of the furnace body, enhance the heat insulation of the furnace, and reduce the heat dissipation loss of the furnace wall.
Coating high-temperature and high-radiation paint on the inner wall of the furnace enclosure strengthens the radiation heat transfer in the industrial kiln and helps to make full use of heat energy. The energy-saving effect is %~%, which is a more advanced energy-saving method.
The above is a detailed introduction to energy-saving measures for industrial kilns. I hope it will be helpful to you.
