Overview, Working Principle and Product Features of High-Power Explosion-Proof Electric Heater
It is a device that converts electrical energy into thermal energy for use in explosion-proof environments. It is used to raise temperature, maintain heat, or heat flowing or stationary liquid, gas, or solid media.
Product Features:
1. Small size, high heating power;
2. Can heat various media in various occasions, such as explosion-proof environments;
3. Heating temperature can usually reach 720°C;
4. The heating system can be fully automated, including control via a DCS system;
5. Long service life, with multiple protection systems, safe and reliable.
Working Principle:
It consumes electrical energy to convert into thermal energy to heat the material to be heated. 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, following the path designed based on fluid thermodynamics, and carries away the high-temperature thermal energy generated by the electric heating elements during operation, 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 medium temperature at the outlet. When the heating element exceeds the temperature, the independent overheat protection device of the heating element immediately cuts off the heating power supply, preventing overheating of the heated material from causing coking, deterioration, or carbonization, and in severe cases, damage to the heating element, effectively extending the service life of the electric heater.
