What are the benefits of choosing a constant power electric heating belt

A constant power electric heating belt has a constant heat generation per unit length and is a type of constant resistance electric heating belt. The longer the electric heating belt used, the greater the total power output. Taking the widely used constant power electric heating wire with a power consumption of 20W per meter as an example. The total length of the pipeline is 1000m, with an hourly electricity consumption of 1000 × 20/1000=20KW. h. When the pipeline temperature reaches the upper limit of the maintenance temperature, the output power enters stability, and the power consumption of electric tracing remains unchanged; The electricity price is calculated at 0.60 yuan/KW. h, and the operating day is 100 days (2400 hours). Therefore, the normal annual electricity consumption cost is 28800 yuan (20 × 2400) × 0.60. When the constant power electric heating belt is used in conjunction with the temperature controller, it can also maintain the medium temperature of the pipeline or heating element.

Self controlled heating belt is a type of variable resistance electric heating belt that adjusts its heat generation based on the temperature of the sensitive pipe wall (medium). Taking the widely used self controlled heating wire with a power consumption of 150000 per meter as an example. The total length of the pipeline is 1000m, and the hourly electricity consumption is 1000 × 15/1000=15KW. h. When the pipeline temperature reaches the upper limit of the maintenance temperature, the heat generated by electric tracing will gradually decrease, and the output power will also decrease accordingly. Therefore, the power consumption of the electric heating belt is generally 60% of the rated power; The electricity price is calculated at 0.60 yuan/KW. h, and the operating day is 100 days (2400 hours). The normal power consumption cost is: (15 × 2400) × 0.60 × 60%=12960 yuan. When used in conjunction with a temperature controller, the self controlled heating belt can not only maintain the medium temperature of the pipeline or heating element, but also further reduce the operating cost.

Conclusion: When using self controlled temperature electric heating belts and constant power electric heating belts for pipeline (equipment) anti freezing and insulation, the one-time investment is similar, but the operating cost of self controlled temperature electric heating belts is significantly reduced, and the economic benefits are very significant. It can be foreseen that the continuous innovation of self controlled temperature electric heating belts will have a wide range of applications in the heat tracing insulation, anticoagulation, and antifreeze of pipelines and storage tanks in industrial enterprises. Its advantages over constant power electric heating belts include energy saving, fast heating without overheating, adjustable cutting length, overlapping without overheating, automatic power output adjustment, automated operation, and automatic temperature control without the need for temperature control.

      Although constant power electric heating belts have many disadvantages compared to self controlled temperature electric heating belts, and the products themselves cannot be intelligent, under certain conditions, there is still a considerable demand for application through auxiliary control in certain high-temperature tracing or heating situations, especially in the tracing or heating of ultra long pipelines.
