Pipeline Insulation Desulfurization Power Plant Electric Heating Cable

Early desurbing pipelines in power plants used steam heating, but were abandoned due to many disadvantages such as uneven heating, excessively high or low temperature, overspending of water resources, and high cost. After years of hard work, the currently used heating and heat preservation equipment is a high-tech electric heating system.

Wet desulphuration is applied to transfer and discharge of desulphurisation pipelines in power plants. When the temperature is relatively low in winter, the sludge freezes and blocks due to the temperature difference, which reduces the efficiency of the equipment and affects the operation of the power plant. Early desurbing pipelines in power plants used steam heating, but were abandoned due to many disadvantages such as uneven heating, excessively high or low temperature, overspending of water resources, and high cost. After years of hard work, the currently used heating and heat preservation equipment is a high-tech electric heating system.

Huaning recommends self-limiting temperature electric heating cables for the characteristics of desulfurization and environmental protection projects in power plants to avoid the phenomenon in which the desulfurization efficiency of various drill pipes and industrial water pipes in the power station desulfurization system freezes in winter. The efficiency of desulfurization is reduced, making them unable to work normally.

Self-regulating temperature electric heating Heating is the use of electric heating equipment to convert electrical energy into thermal energy. Through direct or indirect heat exchange, the heat loss of the heat exchange equipment is supplemented by insulating materials, and temperature control is used to track and control the temperature of the medium in the heat exchange equipment, keeping it at a reasonable economic level. The self-regulating electric heating cable for flue gas desulfurization in thermal power plants consists of a conductive core with PTC characteristics and a composite insulation layer. Long-term use, good insulation performance, good anti-aging performance, low pressure.

Due to the acid and alkali solution transported in the desulfurization system, the desulfurization pipeline must have anti-corrosion, wear-resistant and heat-resistant functions to ensure the normal operation of the desulfurization system. The electric heating cable used in the insulation of desulfurization pipelines must also be anti-corrosion and explosion-proof.

Electrical heating installation precautions

Electric heating cable is a heating method that uses insulation resistance or resistance heating wire to create a temperature after power supply. It can automatically adjust the output temperature and reasonably maintain the process temperature requirements to keep warm, raise the temperature and protect the heating equipment from freezing. The insulation and antifreeze effect of the container is very good.

Which electric heating should be chosen for the main pipeline transport of heavy oil

Transport of heavy oil through the pipeline over long distances and long-term retention in the pipeline will result in a drop in temperature due to heat dissipation and increased viscosity, which will cause the pipeline to be blocked by freezing or condensation-related accidents. Electric heating is widely used as effective insulation of pipelines and anti-freeze protection.

Which electric heating cable should be considered for a 4 km pipeline

According to the statistics of the Hydrometeorological Center, the average daily minimum temperature at the location of the CNPC tank farm is 5 ° C, and the average daily maximum temperature is 14 ° C. Since the freezing point of the PX is about 15 °C, the supply pipeline needs heat preservation and heating. The oil depot has been in operation for many years without a stable source of steam, therefore, this project is considering the use of electric heating technology.

Application of outdoor electric heating cable in oil main pipelines with high paraffin content

Long-distance crude oil pipelines with a high paraffin content with freezing temperatures above 50 °C. According to the requirements of the production plan of the plant, the volume of oil transportation through the pipeline is 150 thousand rubles. Tons per year, maximum-200 thousand. Tons per year.. According to the thermodynamic analysis of the pipeline, the initial supply temperature of the pipeline is 80 ° C (TN), and the temperature of the end entering the tank is 60 ° C (Tu). Since the transportation temperature needs to be adjusted according to the time of year, it sometimes needs to be transported by heat.

What heating product to choose for main infusion pipelines

In petrochemical engineering, trunk infusion pipelines are the lifeblood of the factories. The temperature in the northern region is too low in winter and the pipeline needs to be insulated to compensate for the heat loss due to the low temperature in winter to ensure the normal operation of the pipeline.

The role of leather tracer cables in the insulation of asphalt main pipelines

The toughness of the asphalt is greatly affected by the temperature. When the temperature decreases, the toughness of the asphalt increases, and the drop in resistance of the asphalt during pipeline transportation increases; when the temperature falls below the freezing point, the asphalt solidifies, causing the pipeline to clog and the conveyor belt to come to trouble. Therefore, electric heating and heat preservation during the transportation of asphalt are very important.
