- Commodity name: Desulfurization and denitrification heating and insulation system for power plants
The desulfurization and denitrification system is a device that carries out chemical reactions in high-temperature flue gas, and the temperature of its internal equipment and pipelines needs to be stable within a certain range to ensure the normal operation and effect of the system. Therefore, it is very necessary to insulate the system. Thermal insulation not only reduces heat loss and saves energy, but also protects equipment from corrosion and damage, extending the service life of equipment.

The desulfurization and denitrification system is a device that carries out chemical reactions in high-temperature flue gas, and the temperature of its internal equipment and pipelines needs to be stable within a certain range to ensure the normal operation and effect of the system. Therefore, it is very necessary to insulate the system. Thermal insulation not only reduces heat loss and saves energy, but also protects equipment from corrosion and damage, extending the service life of equipment.
► Composition of the heat tracing system
The main components of the electric heat tracing system: intelligent temperature control distribution box, self-limiting temperature electric heat tracing, power junction box, two-way junction box, three-way junction box, terminal junction box, thickened aluminum foil tape, heat-resistant pressure-sensitive tape, temperature sensor, stainless steel cable tie, special distribution box for electric heating, insulation layer, etc.
System Advantages:
1. Cost-effective: The electric heat tracing designed and selected by our company has a long service life, low maintenance rate and high heat transfer rate. The advantages of YATALO self-limiting electric heat tracing: low starting current, low upfront power distribution cost, long service life, low maintenance cost in the later stage, low power consumption for long-term operation, and high heat conversion rate. We pay attention to the quality of each single product and the professional quality of system integration products, so as to achieve the effect of reducing costs and increasing efficiency in the real sense.
2. Safety guarantee: The main performance items of YATALO electric heating product manufacturing standards meet the GB/T19835-2015 standard, and the product materials are made of high-quality materials to ensure that the performance of the electric heat tracing meets the standards, with good thermal stability, low starting current, uniform heating temperature, heating temperature is within the standard range, will not overheat or short circuit lead to heat tracing combustion or burning, long service life, low attenuation of power meter, and high cost of replacement cycle caused by short life.

Installation specification steps: check whether the surface of the pipeline is polished smooth and free of burrs and sharp edges, dry and free of dirt; Check whether the paint inside the pipe is dry and the gas has evaporated for more than 3 weeks; Check whether the corresponding heating tracing materials and accessories are consistent with the materials in the design table; Check whether the materials required for construction are in good condition, etc.
Construction and installation points: the installation of electric heat tracing on the pipeline generally adopts the way of straight laying or winding, during installation, every interval of 300-600mm is fixed with heat-resistant pressure-sensitive tape, after the installation is completed, along the direction of the electric heat tracing is covered with a layer of aluminum foil tape, which is used to increase the heating area of the pipeline, the power junction box and the temperature sensor are fixed on the pipeline with stainless steel tape, and the two-way junction box and the three-way junction box can be fixed with heat-resistant pressure-sensitive tape when the temperature is not high. When the temperature is higher than 200°C, it is generally fixed with stainless steel cable ties.►Application examples
