[Chemical Knowledge]:Brief Description of Working Principle of Tube Heating Furnace

Tubular heating furnace is a common high-temperature heating equipment, which mainly uses a shell-and-tube structure, and the electric heating rod or other heating elements are arranged in the tube to achieve the purpose of heating the medium in the tube. So, what is the working principle of the tube heating furnace? Here are some simple introductions.

1. structure characteristics

Under normal circumstances, the tubular heating furnace is composed of pipe body, heating element, import and export, refrigerator and other parts. Among them, the tube body is the main component of the whole heating furnace, which usually uses stainless steel, specially treated aluminum alloy or other metal materials, which has good high temperature resistance and corrosion resistance. Heating elements are the main way to conduct heat, including spiral electric heating rods, electric heating tubes, etc. different heating materials have different characteristics and scope of application. The inlet and outlet are the channels connecting the tube body and the outside world, which are responsible for adding medium, power supply, etc, as well as the heating of the gas and other substances discharged; the refrigerator is used to control the temperature of the tube body of an auxiliary equipment. The working principle of the

2. The working principle of the

tube heating furnace is very simple, that is, the heating material and the medium in the tube body are heated together to achieve the purpose of heating up. Specifically, when the power is turned on, the heating element begins to heat up, heating the medium in the tube body to a certain high temperature, and the external medium of the tube body also heats up. At this time, the medium in the tube starts to flow, transfers heat through the tube wall, and discharges the heated gas and liquid at the outlet. The entire heating process can be achieved by fine-tuning control.

3. application range

tube heating furnace is widely used in electric power, metallurgy, chemical industry, medicine, light industry and other industrial fields, can be used to heat water, gas, petroleum, chemical liquid, etc., can also be used for furnace charge drying, smelting, baking and other processing. At the same time, because the tubular heating furnace has the advantages of fast heating speed, environmental protection and energy saving, precise heating temperature, simple operation, etc., it is also widely used in laboratories, scientific research institutions and other fields.

To sum up, as a common high-temperature heating equipment, the working principle of the tube heating furnace is very simple, mainly through the heating of the medium in the tube to achieve the purpose of heating. In the scope of application, the tubular heating furnace can be applied to the heating treatment of various substances, and is widely used in industrial fields and laboratories, scientific research institutions and other fields. For users who want to choose a tube heating furnace, they can choose different heating materials and models according to their needs to obtain the best heating effect.
