Radiant Electric Heating Tube: Principles, Applications, and Development
Abstract
This article introduces the working principle, main features, application fields, and future development trends of radiant electric heating tubes. Due to their efficient heating performance, uniform heating effect, and energy-saving and environmentally friendly characteristics, radiant electric heating tubes have been widely used in multiple industries.
Introduction
Radiant electric heating tube is an electric heating element that transfers heat through radiation. It can heat objects quickly and uniformly, while reducing energy waste and improving production efficiency.
Working Principle
The working principle of radiant electric heating tube is to enclose the electric heating element inside a protective sheath. After being energized and heated, the sheath indirectly radiates heat to the furnace lining and the workpiece being heated. The heating element is usually installed in a sheath made of heat-resistant stainless steel, which isolates the heating element from the gas medium in the furnace, preventing corrosion of the heating element by the medium. To prevent deformation of the heating element at high temperatures and short circuits with the sheath, the heating element is usually pre-installed on special supports made of insulating refractory materials. During operation, current is introduced into the heating element through the power connector and lead-out rod. The heat generated by the heating element heats the sheath, and through the high-temperature radiation effect of the stainless steel tube surface, heat is transferred to the object being heated.
