The Working Principle Of Steam Heaters
Jun 28, 2017

The steam heater uses the aluminum-aluminum composite finned tube as the main heat exchanger element. Due to the use of advanced composite process, in the tube temperature of 210 degrees below the basic contactless thermal resistance. The steam heater combines the pressure resistance of the steel pipe and the high thermal conductivity of the aluminum, excellent heat transfer performance, Steam (heat Exchanger) Electric Heater and avoids the direct contact between the steel pipe and the air, and the corrosion resistance has also been effectively improved. Because the fins without wrinkles, so the air resistance than the winding type low. Steam heater products also have easy to water, easy to clean, compact structure, the unit heat transfer area and other advantages.

The working principle is to put a number of turns more primary coil and a smaller number of secondary coil mounted on the same core. The input and output voltage ratio is equal to the number of turns of the coil, while the energy remains constant. As a result, Steam (heat Exchanger) Electric Heater the secondary coil generates a high current at low voltage. For induction heaters, the bearing is a short-circuit single-turn secondary coil, under low AC voltage conditions through the high current, resulting in a lot of heat. The heater itself and the yoke are kept at room temperature. Since this heating method can induce current, the bearing is magnetized. Steam (heat Exchanger) Electric Heater It is important to ensure that the bearing after the demagnetization, so that in the course of operation will not suck metal chip. FAG induction heaters have automatic demagnetization function.

Is the use of metal in the alternating magnetic field generated eddy current and make their own heat, usually used in metal heat treatment and so on. The principle is that when the thicker metal is in an alternating magnetic field, the current is generated by the electromagnetic induction. And the thicker metal to generate current, the current will form a spiral within the metal flow path, Steam (heat Exchanger) Electric Heater so that the current flow of heat generated by the metal itself is absorbed, will lead to metal heating soon. The device is an energy-saving device for preheating or secondary heating of fuel oil, which is installed before the combustion equipment to achieve heating of the fuel oil prior to combustion to a reduced temperature at a high temperature (105 ° C to 150 ° C) Fuel oil viscosity, and promote the full atomization of combustion and other effects, and ultimately achieve the purpose of saving energy. It is widely used in heavy oil, asphalt, oil and other fuel oil preheating or secondary heating occasions.
