Working principle of explosion-proof heater
Working principle
It is a device that consumes electrical energy and converts it into thermal energy to heat the material to be heated. During operation, the low-temperature fluid medium enters its inlet 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 principles, and takes away the high-temperature thermal energy generated by the electric heating element during operation, thereby increasing 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, which could cause coking, deterioration, carbonization, or even damage to the heating element in severe cases, effectively extending the service life of the electric heater.
