Furnace structure and transformation are convenient for energy saving

Furnace structure and transformation are convenient for energy saving

(Summary description)The use of a circular furnace instead of a box-shaped furnace can strengthen the uniform heat transfer effect of the furnace to the workpiece, reduce the heat dissipation of the furnace wall, and make the furnace form a heat exchange system to exchange heat between the heating element, the furnace lining and the workpiece. By adopting a reasonable furnace space and without increasing the volume of the furnace space, the furnace inner wall area is enlarged, and the furnace heat exchange is increased by increasing the heat exchange area to increase the heat efficiency.

Information

(1) The use of a circular hearth instead of a box-shaped hearth can strengthen the uniform heat transfer effect of the hearth on the workpiece, reduce the heat dissipation of the furnace wall, and make the hearth form a heat exchange system to conduct heat between the heating element, the furnace lining and the workpiece. exchange. By adopting a reasonable furnace space and without increasing the volume of the furnace space, the furnace inner wall area is enlarged, and the furnace heat exchange is increased by increasing the heat exchange area to increase the heat efficiency.

(2) In the industrial furnace, a fan is installed in the furnace to enhance the convective heat transfer in the furnace. Especially for small heating furnaces, high-speed airflow can destroy the bottom layer of the furnace gas boundary that is stagnant on the surface of the workpiece to hinder heat transfer and interface reaction, which can shorten the heating time and accelerate the increase of the temperature of the workpiece.

(3) Furnace body sealing, including the sealing of all lead-out components in the furnace, furnace shell, furnace door, etc. If the furnace body is not tightly sealed, it will cause fire running and leakage everywhere, resulting in a large amount of energy waste, equipment burnout, and harsh environment. Therefore, the furnace body sealing directly affects the quality of the workpiece and energy consumption, and the sealing is also controlled by the atmosphere in the furnace. The essential. The emergence of refractory fiber products has created conditions for solving furnace body sealing, and industrial furnaces have achieved soft sealing.

Industrial furnace energy saving must have scientific measurement and comparison test methods

The energy saving of industrial furnaces must have scientific measurement and comparison test methods. The currently accepted test method is the heat balance test. Through the thermal measurement of the industrial furnace, we can fully understand the thermal process of the industrial furnace, analyze and diagnose the "disease" of the heating furnace, find out the "cause", and carry out energy-saving technological transformations to further improve the thermal efficiency of the heating furnace. Reduce energy consumption and obtain various parameters of the economic and technical performance indicators for the operation of the heating furnace, analyze the operation of the heating furnace, and adjust the operating conditions of the heating furnace in time to achieve the best state of operation, so as to find an effective way and direction to save energy

Industrial furnace operation

Generally speaking, the high temperature of industrial furnace operation is prone to scalds, burns and burns; high-temperature molten salt and molten metal will explode after encountering water; gas and controllable atmosphere are explosive gases, and oil circuits, fuel tanks and oil depots are all Inflammable and explosive facilities, if the electric furnace type industrial furnace is used improperly, explosion and poisoning accidents will occur
