Benefit Analysis of Using Heat Tracing
Self-regulating electric heat tracing adjusts its heat output based on the temperature of the sensitive pipe wall (medium), making it an energy-saving measure. The most widely used self-regulating heat tracing cable consumes 15W per meter. For a pipeline with a total length of 1000m, the hourly power consumption is 1000×15/1000=15KW.h. When the pipeline temperature reaches the upper maintenance temperature, the heat output of the heat tracing gradually decreases, and the output power also drops accordingly. Thus, the actual power consumption of the heat tracing is generally 60% of the rated power. Assuming the plant electricity price is 0.60 yuan/KW.h and the operation period is 100 days (2400 hours), the annual normal electricity cost is: (15×2400)×0.60×60%=12960 yuan. When used in conjunction with a thermostat, self-regulating heat tracing can not only precisely maintain the medium temperature of the pipeline or heated body
