Energy-saving measures for tubular electric furnace

Tubular electric furnace manufacturers believe that energy conservation requires scientific measurement and comparison testing methods. The currently accepted test method is the heat balance test. Through the thermal measurement of the industrial furnace, 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 and reduce the unit consumption. , And obtain various parameters of the economic and technical performance indicators for the operation of the heating furnace, analyze the operating conditions of the heating furnace, and adjust the operating conditions of the heating furnace in time to achieve a better state of operation, so as to find an effective way and direction to save energy.

When designing or improving the furnace, new energy-saving industrial furnaces should be selected as far as possible according to the requirements of the production process. Choose a suitable furnace structure to improve the degree of mechanization and energy efficiency. The energy-saving measures commonly used at present are:

(1) 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 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) Install a fan in the furnace to enhance 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.
