Heating element principle to prevent dry burning (heating element)

Anti-dry-burning electric heating tubes are a type of electric heating element. Existing electric heating tubes that use liquid as the heating medium have a fatal flaw. Under abnormal conditions, i.e., when dry burning occurs, the heating tube will burn out or explode within a short time, causing inconvenience to the user. Specifically, when the temperature reaches a certain point, the metal sheet inside the anti-dry-burning protector deforms due to heat, causing the power supply to be isolated. It mainly relies on the conductivity of impurities in the water to form a circuit. The amount of water determines the amount of heating of the resistance wire, eliminating the worry of dry burning.

Electric Heating Tube Specifications

Electric heating tubes generally come in models such as XY-JRB-011, TY-GYG-W-1008HT, -SR-208, RE-302, HY--1Y, etc. The price varies depending on the model. This depends on your specific needs.

Electric Heating Radiant Tubes

Electric heating tubes radiate heat. Electric heating tubes, also known as heating elements or heating tubes, are scientifically called tubular electric heating elements. They place coiled heating wire (resistance wire) inside a metal tube, and fill the surrounding area and gaps with heat-resistant, thermally conductive, and insulating powder (MgO). Lead rods or lead wires are added to both ends of the heating element. It features simple structure, high mechanical strength, high thermal efficiency, safety and reliability, convenient installation, and long service life. It is widely used in various nitrate tanks, water tanks, oil tanks, acid and alkali tanks, fusible metal melting furnaces, air heating furnaces, drying furnaces, drying boxes, hot press molds, and other devices. Electric heating tubes are electrical components specifically designed to convert electrical energy into heat energy. Due to their low price, ease of use, convenient installation, and pollution-free operation, they are widely used in various heating applications.

Electric Heating Tube Prices

Double U-shaped Stainless Steel Rice Cooker, Rice Cooker Heating Element, Water Tank, Electric Heating Element 220V/3KW, 18 yuan. This heating element is double U-shaped, with a length of 320mm downwards from the fastener. Although it is double U-shaped, each heating element is marked with its power and voltage, so careful inspection is necessary when selecting. The most common application of this type of heating element is in the proofing box of rice steamers. This type of heating element is made entirely of stainless steel. It is made with high-quality heating wire and is safe to use.

Electric Heating Element

An electric heating element is made by welding heating wires together inside a seamless metal tube. Carbon steel, titanium, copper, and stainless steel tubes can be used. Magnesium oxide powder (the magnesium powder must be free of impurities, otherwise the heating element will burst after prolonged use) is then filled into the gaps between the tubes. The tube is then shrunk and processed into the desired shape. Magnesium oxide has good thermal conductivity and insulation, allowing it to transfer heat effectively. Although the electric heating element has a simple structure, it has good thermal efficiency and mechanical strength. It can be used to heat various acid, alkali, and salt liquids, and can also be used to melt some metals that are easily fusible at low temperatures.
