- Description
-
- Commodity name: Power plant ash hopper heat tracing and temperature maintenance system
The fly ash in the ash hopper of the waste incineration power plant will condense at about 120-130°C, which will cause the solidification, compression or formation of dust, which can lead to the clogging of the ash hopper. In order to prevent this phenomenon from occurring, an electric heat tracing system is required to keep the ash hopper heat warm to prevent the formation of solidification and agglomeration, to preheat the ash hopper so that moisture evaporation may be formed, and to maintain the temperature of the ash hopper and fly ash above the dew point.
► Application scenario
The fly ash in the ash hopper of the waste incineration power plant will condense at about 120-130°C, which will cause the solidification, compression or formation of dust, which can lead to the clogging of the ash hopper. In order to prevent this phenomenon from occurring, an electric heat tracing system is required to keep the ash hopper heat warm to prevent the formation of solidification and agglomeration, to preheat the ash hopper so that moisture evaporation may be formed, and to maintain the temperature of the ash hopper and fly ash above the dew point.
► Pipeline anti-freezing and heat tracing system
The main components of the electric heating system: intelligent temperature control distribution box, MI armored electric heat tracing, power 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 MI armored electric heat tracing: low power distribution cost in the early stage, long service life, low maintenance cost in the later stage, low power consumption in 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.
► How it works
The temperature sensor installed on the ash hopper will be transmitted to the temperature control instrument in the intelligent temperature control distribution box through the signal cable, the temperature control meter will compare the temperature received with the set temperature, when the current temperature is greater than the set temperature, the electric heat tracing will not work, when the current temperature is less than the set temperature, the electric heat tracing will start working, in order to avoid frequent start-up, generally set a return difference, the distribution box can also be connected with the central control room or DCS system for remote communication, and the start and stop of the electric heat tracing can be observed and controlled at the remote end.

Product model
Product features: The advantages of MI armored electric heat tracing: low power distribution cost in the early stage, long service life, low maintenance cost in the later stage, low power consumption in long-term operation, and high heat conversion rate.
► Construction and installation
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 ash hopper generally adopts the winding method, 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, and the power junction box and temperature sensor are fixed on the ash hopper with stainless steel tape.
