Introduction:
Duct-type Electric Heater is an energy-saving device that generates heat through electricity and preheats materials. It is installed before the material equipment to directly heat the material, allowing it to circulate and heat under high temperature, ultimately achieving energy conservation. It is widely used for preheating heavy oil, asphalt, clear oil, and other fuel oils.
It is an internationally popular high-quality, long-life electric heating device. It is used for raising, maintaining, and heating the temperature of flowing liquid and gaseous media. When the heating medium passes through the heating chamber of the electric heater under pressure, the fluid thermodynamics principle is used to uniformly remove the huge heat generated by the electric heating elements during operation, raising the temperature of the heated medium to meet the user's process requirements.
Working Principle:
Explosion-proof Electric Heater is a device that converts electrical energy into heat to heat the required materials. During operation, the low-temperature fluid medium enters the input port through the pipeline under pressure, flows along the specific heat exchange channel inside the electric heating container, and uses the path designed based on fluid thermodynamics principles to take away the high-temperature thermal energy generated by the electric heating elements, raising the temperature of the heated medium. The outlet of the electric heater provides the high-temperature medium required by the process. The internal control system of the electric heater automatically adjusts the output power based on the temperature sensor signal at the outlet to ensure uniform temperature of the medium at the outlet. When the heating element overheats, the independent overheat protection device immediately cuts off the heating power supply, preventing the heated material from overheating, coking, deteriorating, or carbonizing, which could otherwise damage the heating element, effectively extending the service life of the electric heater.
Application Scope
1. Heating of chemical materials in the chemical industry, drying of certain powders under pressure, chemical processes, and spray drying.
2. Heating of hydrocarbons, including crude oil, heavy oil, fuel oil, thermal oil, lubricating oil, paraffin, etc.
3. Heating of process water, superheated steam, molten salt, nitrogen (air) gas, water gas, and other fluids that require temperature increase.
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.
