Steam pipeline electric heater

Short Description:

Steam pipeline electric heater as a special electric heating equipment, in the design and production process, must comply with the relevant explosion-proof codes and standards. The explosion-proof electric heater adopts explosion-proof structural design and explosion-proof housing, which can effectively prevent the impact of sparks and high temperature generated by electric heating elements on the surrounding flammable gas and dust, thus avoiding potential safety hazards. Explosion-proof electric heater also has multiple protection functions, such as over-current protection, over-voltage protection, lack of phase protection, etc., which can effectively protect the safety of the equipment itself and the surrounding equipment.

Working principle

Electric heating element generates heat: The electric heating element in the heater is the core part of generating heat. When an electric current passes through these elements, they generate a lot of heat.

Forced convection heating: When nitrogen or other medium passes through the heater, the pump is used to force convection, so that the medium flows and passes through the heating element. In this way, the medium, as a heat carrier, can effectively absorb heat and transfer it to the system that needs to be heated.

Temperature control: The heater is equipped with a control system including temperature sensor and PID controller. These components work together to automatically adjust the output power of the heater according to the outlet temperature, ensuring that the medium temperature is stable at the set value.

Overheating protection: In order to prevent overheating damage to the heating element, the heater is also equipped with overheating protection devices. As soon as overheating is detected, the device immediately cuts off the power supply, protecting the heating element and the system.

Product advantage

1, the medium can be heated to a very high temperature, up to 850 ° C, the shell temperature is only about 50 ° C;

2, high efficiency: up to 0.9 or more;

3, the heating and cooling rate is fast, up to 10℃/S, the adjustment process is fast and stable. There will be no temperature lead and lag phenomenon of the controlled medium, which will cause the control temperature drift, suitable for automatic control;

4, good mechanical properties: because its heating body is special alloy material, so under the impact of high pressure air flow, it is better than any heating body mechanical properties and strength, which requires a long time continuous air heating system and accessories test is more advantageous;

5. When it does not violate the use process, the life can be as long as several decades, which is durable;

6, clean air, small size;

7, the pipeline heater can be designed according to the needs of users, multiple types of air electric heaters.

Working condition application overview

Secondary heating Electric heaters are used to reheat steam to raise its temperature after it has already been generated.

This is usually achieved by adding an electric heater at the end of the steam pipe to ensure that the temperature of the radiator at the end of the pipe reaches a set value, thereby increasing the heating effect of the space or achieving the steam temperature required for the terminal thermal equipment, and the heating process does not change the steam pressure at the outlet.

Due to the instability of the steam medium flow, the control is usually controlled by thyristor precision to ensure the stability of the outlet steam temperature.

In summary, the working principle of the steam secondary heating electric heater involves the process of converting electrical energy into heat energy, accurately controlling the generation of steam and secondary heating through the automatic control system, as well as the design of the safety protection system, to ensure its efficient and safe operation.
