The principle of electric heater
Electric heater works by using an alternating magnetic field, turns more of a primary and a secondary coil that turns less load on thesame core. Input and output voltage ratio equal to the ratio between the number of turns of the coil, while energy remains constant. Therefore, secondary coils produce high current at low voltage conditions. For the induction heater, bearing a short single turn secondary coil in the lower AC voltage under the conditions of high current,resulting in a great deal of heat. Held at room temperature in the heater itself and yoke. Because of this heating method can detect acurrent, so the bearing is magnetized. Is important to ensure that the bearing after degaussing, the operation does not hold metal magnetic chip. FAG induction heaters have automatic degaussing function. Is the use of metal in an alternating magnetic field of eddy currents in the fever itself, is commonly used in metal heat treatmentand so on. Principle is a thick metal in an alternating magnetic fieldwhen current due to electromagnetic induction phenomenon. Thicker metal when its current, current will be formed inside the metal spiral flow path, so that the heat generated due to current flow is absorbed by the metal itself, leads to metal quickly heating up. Thedevice is a type of fuel oil preheating or secondary heating energy-saving equipment and install it prior to combustion equipment, realize the heating of fuel oil before burning, make it at high temperature (105-150 ℃), to reduce the viscosity of the oil, promote full spray combustion, and ultimately achieve the goal of energy conservation. It is widely used in heavy oil, bitumen, oil and other fuel oil heating or reheating of the occasion in advance.
