Advantages and Applications of Circulating Electric Heaters
With the development of the power industry and the increasing scale of chemical plants, the design and application of circulating electric heaters in China will become more and more common. This article mainly introduces the characteristics and applications of circulating electric heaters.
1. Advantages of Circulating Electric Heaters:
1. Small size, high power: The circulating electric heater mainly uses bundled tubular heating elements inside, which can accommodate more tubular electric heating elements per unit volume, thereby increasing the heat exchange area per unit volume and greatly reducing the device size. The maximum power of each bundled tubular electric heating element group is.
2. Fast thermal response, high temperature control accuracy, high overall thermal efficiency: Since the circulating electric heater directly transfers heat energy to the heated medium, its electrical energy conversion efficiency is above. In contrast, traditional heat exchangers use heat media such as thermal oil from thermal oil furnaces or steam from steam heat exchangers, which involve secondary thermal conversion. Additionally, the fast thermal response and high temperature control accuracy of this electric heater not only reduce process auxiliary time and effectively ensure process control temperature accuracy but also improve overall thermal efficiency and reduce unnecessary process energy loss.
3. Wide application range, strong adaptability: The circulating electric heater can heat various gases and fluids, whether acid, alkali, or oil and gas, whether in explosion-proof occasions or general environments, whether high-pressure circulation or atmospheric pressure devices, this electric heater can adapt. Its explosion-proof grade can reach level and level, and its pressure resistance can reach.
4. High heating temperature: The maximum working temperature of the circulating electric heater can reach“ ℃ ,
