Boiler electric heating tube , which refers to the electric heating device used for boiler heating. The stainless steel electric heating tube uses a metal tube as its outer shell. Spiral electric heating alloy wire (nickel-chromium, iron-chromium alloy) is uniformly distributed in the center axis, and the gap is filled and compacted with magnesia with good insulation and thermal conductivity, and both ends of the nozzle are sealed with silica gel or ceramic. Stainless steel electric heating tube is an electrical component that specializing in converting electrical energy into thermal energy. Due to its high thermal efficiency, easy use, simple installation, and no pollution, it is widely used in various heating occasions, and it is more commonly used in electric heating boilers. The service life of stainless steel electric heating pipes is very long, and service life is more than 10,000 hours usually.
Features of Stainless Steel Boiler Electric Tubular Heater:
1. Small size and high power: The bundled tubular heating element is mainly used in the electric heater, and the maximum power of each bundled tubular heating element is 5000KW.
2. Fast thermal response, high temperature control accuracy and high comprehensive thermal efficiency.
3. Wide application range and strong adaptability: The circulating heater can be used in explosion-proof or ordinary occasions. Its explosion-proof grade can reach B and C grades, and its pressure resistance can reach 10Mpa. And the cylinder can be installed vertically or horizontally according to user needs.
4. High heating temperature: The designed maximum working temperature can reach 850℃, which is not available for general heat exchangers.
5. Fully automatic control: Through the heater circuit, it realizes automatic control of parameters such as outlet temperature, pressure, and flow rate, and it can be networked with a computer to make a man-machine dialogue.
6. Long life and high reliability: The heater is made of special electric heating materials, and the design power load is reasonable. The heater has multiple protections, which greatly increases the safety and life of the heater.
Connection Method Features of Stainless Steel Boiler Electric Tubular Heater:
Generally use three phases, symmetrically connected into a star (Y) or triangle (△) shape. Divided into two or more groups based on capacity.
