Explosion-proof electric heaters are mainly used in the following applications - Yangzhou Darui
Darui Electric recommends
1. Heating of chemical materials in the chemical industry, drying of powders under certain pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin wax, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air), water gas, and other fluids that require heating.
4. Due to the advanced explosion-proof structure, the equipment can be widely used in chemical, military, petroleum, natural gas, offshore platforms, ships, mining areas, and other places requiring explosion protection.
Explosion-proof electric heater working principle:
It is a device that converts electrical energy into heat energy to heat the material to be heated. During operation, the low-temperature fluid medium enters the input port under pressure through the pipeline, flows along the specific heat exchange channel inside the electric heating container, follows the path designed based on fluid thermodynamics principles, and takes away the high-temperature thermal energy generated by the electric heating element during operation, thereby raising the temperature of the heated medium. The outlet of the electric heater obtains the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power of the electric heater based on the temperature sensor signal at the outlet, ensuring uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing the heated material from overheating and causing coking, deterioration, or carbonization, which could otherwise damage the heating element in severe cases, effectively extending the service life of the electric heater.
