Quartz Heater Tubes: Principles and Construction

Quartz heating tubes are widely recognized heating elements in both industrial and scientific settings. Let’s explore the principles and design that underpin their functionality.

The fundamental heating mechanism of quartz heating tubes involves resistance heating. By passing an electric current through the tube, heat is generated within, which then gets transferred to the tube walls. This heat is subsequently conveyed to the object requiring heating through radiation, convection, and conduction. The electrical resistance within the tube produces heat, raising the temperature of the quartz walls and effectively warming the targeted object.

Constructed primarily from quartz glass, quartz heating tubes boast remarkable resistance to high temperatures and chemical stability. Their design comprises three key elements: the quartz tube walls, the heating wire, and an insulation layer.

The core of the heating tube, these walls are highly resistant to heat and excellent at transferring it, making them capable of enduring the rigors of high-temperature heating.

Situated inside the quartz tube, this wire is typically made from materials like nickel-chromium alloy. It achieves resistance heating by winding inside the tube.

This layer wraps around the heating wire, preventing direct contact with the quartz walls while also serving an insulating and heat-retention role.

Moreover, quartz heating tubes might include auxiliary components such as conductive terminals and brackets. These are critical for connecting to a power source and securely positioning the tube.

Utilizing the principle of resistance heating and capitalizing on the exceptional qualities of quartz glass, quartz heating tubes emerge as a dependable and efficient heating solution across various industry sectors.
