Potential Safety Hazards Caused by Improper Use of Explosion-Proof Electric Heaters? - Yangzhou Darui
Darui Electric recommends for you
Explosion-proof electric heaters are one of the most commonly used equipment in work and daily life. Their safety is closely related to our safety. Therefore, when using them, we repeatedly emphasize the need to pay more attention to prevent safety risks and fully ensure the safe operation of the electric heater.
This product uses heating wires made of nickel and nickel-iron alloy, whose temperature can reach above 800°C. Because the power of explosion-proof electric heaters is relatively large, if you are not careful during use, there is a high possibility of fire accidents.
Potential safety hazards caused by improper use of equipment:
1. Combustion of combustibles:
Some users place the powered electric heater on or near flammable materials, causing fires under long-term high-temperature baking.
2. Short circuit due to no plug:
The explosion-proof electric heater is not equipped with a power plug at all, but directly inserts the cable head into the power socket, which easily causes short circuits and fires. Another situation is that when users leave, they do not unplug the electric heater, leading to overheating over time, igniting adjacent combustibles and causing fires. In addition, if the heating wire of the electric heater has been repaired many times and is still used, it can also cause fires.
Technical requirements:
1. Application working conditions: Heating air, air temperature entering the electric heater is 150°C, flow rate 1200 Nm3/h, pressure 0.8 MPa; after heating, the air temperature exiting the electric heater is 250°C.
2. Electric heating tubes are designed, manufactured, and accepted according to JB/T2379-93 standard. Waterproof rating: IP54, protection level: dⅡBT4.
3. The electric heater is designed, manufactured, and accepted according to GB3836.1-3-2000 standard.
4. The power design margin of the explosion-proof electric heater is 15-20%.
5. The automatic control system can be adjusted manually and automatically, and can perform stepless adjustment. Under stable conditions, the accuracy is ±1°C. The automatic control system has indicators for input voltage, output voltage, current, temperature, operation, etc., and protections such as overload, short circuit, and over temperature.
6. The casing is designed, manufactured, and accepted according to GB150-1998 "Steel Pressure Vessels" standard.
