Thermal efficiency comparison of electromagnetic heating roller :(infrared heating, resistance wire heating, heat conduction oil heating, natural gas heating, boiler coal heating)
1.The electromagnetic heating: by electronic circuit to produce alternating magnetic field eddy current effect for heating body, the surface of the container with the cutting of alternating magnetic field lines, and the container at the bottom of the metal parts produce alternating current (eddy current), eddy current to make high-speed movement of container at the bottom of the iron atoms, atoms collide with each other, friction and generate heat, to heating effect of the item. Because it is the iron body itself heating, that is, non-contact induction heating, leakage safety is the highest, the heat conversion rate of more than 92%.
2.Resistance wire heating: when the current through the resistance, electric current and electric consumption, the heat energy produced is heat resistance wire itself red again by air or by contact with heat conduction, the biggest drawback resistance wire contact itself is easy oxidation of high temperature, leakage security is the inevitable resistance wire heating, heat efficiency more than 50%.
3.Heat conduction oil heating: inside the station through the resistance wire heating heat conduction oil through the oil pump will be hot oil through pipes to need heating roller after internal circulation within the back to the station to continue heating, in the process of oil transportation, gas station, oil pump, tubing, the parts has become the consumption of thermal radiator, really very little effect on the need for heating roller, and heat conduction oil heating have the following questions (1, equal power heating up slowly, power consumption is too big. 2. When the resistance wire heats up during heating, it will decompose the heat conduction oil at high temperature, so the oil smoke will be emitted into the air and fall on the products in the oil station, which will produce a chemical reaction and seriously affect the product quality. 4. Oil spill in the workshop seriously affects the environment of the workshop and the health of workers. 5. The heating oil station is not well maintained and controlled, which may cause explosion and endanger personal safety. 6. Tedious operation, difficult temperature control), over 30% conversion efficiency.
4.Boiler coal heating: through the combustion of coal to generate heat source, need special boiler room, boiler workers, transport coal, environmental pollution, has been basically banned by the government.
