Basic knowledge and applications of environmentally friendly explosion-proof electric heaters
Explosion-proof electric heaters are generally used in hazardous locations where explosions may occur. Since there are various flammable and explosive oils, gases, dusts, etc. in the surrounding environment, contact with electric sparks can cause explosions. Therefore, in such occasions, explosion-proof electric heaters are required for heating. The main explosion-proof measure of explosion-proof electric heaters is that there is an explosion-proof device in the junction box of the electric heater to eliminate the risk of ignition by electric sparks. For different heating occasions, the explosion-proof level requirements of electric heaters are also different, depending on the specific situation.
Typical application occasions of explosion-proof electric heaters mainly include heating and raising temperature of chemical materials in the chemical industry, drying some powders under certain pressure, chemical processes and spray drying. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, heat transfer oil, lubricating oil, paraffin, etc.; process water, superheated steam, molten salt, nitrogen (air), water gas, etc.
