Application of Electric Heat Tracing in Thermal Systems of Power Plants

In the thermal system of a power plant, the insulation and preheating of pipes and equipment are key links to ensure the normal operation of the system. As an efficient and environmentally friendly heating method, electric heating technology has gradually been widely used in the thermal system of a power plant.

Electric heating technology is a technology that converts electrical energy into thermal energy and heats pipes, containers and other equipment through heating elements such as heating cables or electric heating tapes. This technology has the advantages of high efficiency and energy saving, environmental protection and pollution-free, safety and reliability, and plays an important role in the thermal system of power plants.

In the thermal system of a power plant, many pipelines need to transport high-temperature and high-pressure media, such as steam and hot water. In cold areas or in winter, these pipelines are prone to freezing, leading to safety accidents such as pipeline rupture and leakage. In order to ensure the normal operation of the pipeline, the pipeline needs to be insulated. As an effective insulation and heating equipment, the self-controlling electric heating cable performs well in pipeline insulation.

The self-regulating electric heating belt has the function of automatically adjusting the temperature. It can automatically adjust the heating power according to the actual temperature of the pipeline to ensure that the pipeline temperature is always maintained within the set range. This intelligent temperature control method not only improves the efficiency of pipeline insulation, but also reduces energy consumption. At the same time, the self-regulating electric heating belt also has the advantages of easy installation and convenient maintenance, providing a reliable solution for the pipeline insulation of the thermal system of the power plant.

During the startup and shutdown of a power plant, some equipment or pipelines need to be preheated to ensure the normal operation of the system. As a high-performance heating cable, armored electric heating cables have unique advantages in pipeline preheating.

The electric heating cable adopts a seamless integrated design, has good anti-penetration performance, and can withstand harsh environments such as high temperature and high pressure. Its metal sheath structure makes the armored electric heating cable resistant to high temperature, corrosion, water, fire and explosion, and is very suitable for use in dangerous areas such as power plants. In addition, the armored electric heating cable also has the advantages of fast heating speed and uniform temperature distribution, which can quickly increase the temperature of the pipeline, reduce the thermal stress and mechanical stress caused by temperature changes, and ensure the safe and stable operation of the equipment.

During the pipeline preheating process, the armored electric heating cable can adjust the heating power and heating time as needed to achieve precise preheating control. Through the intelligent control system, the armored electric heating cable can be seamlessly connected with the thermal system of the power plant, realize automatic control and remote monitoring, and improve the operating efficiency and safety of the thermal system of the power plant.

The application of electric heating technology in the thermal system of power plants is of great significance. Self-controlled electric heating belts perform well in pipeline insulation, with the advantages of automatic temperature adjustment, high efficiency and energy saving, and easy installation; armored electric heating belts show unique advantages in pipeline preheating, with high temperature resistance, corrosion resistance, waterproof, fireproof, explosion-proof and other characteristics, which can quickly increase the temperature of the pipeline and ensure the safe and stable operation of the equipment.
