Heating method for pipeline heaters

Heating method for pipeline heaters

The reason why electric heaters can be pursued and chosen by many enterprises is naturally due to many advantages that other fuels or mechanical equipment cannot achieve, such as high temperature, such as arc heating, which can reach three dry degrees Celsius, uniform and stable heating, which is also the reason why fuel has nowhere to operate. In addition, intelligent system devices save manpower and are easy and accurate to operate. How is an electric heater heated? Next, the explosion-proof electric heater will briefly introduce various heating methods.

At present, electric heaters have six heating methods: medium heating, resistance heating, induction heating, infrared heating, arc heating, and electron beam heating. The difference between these heating methods lies in the method of converting electrical energy.

Taking medium heating as an example. The basic principle is to use insulating materials to heat in a high-frequency electric field, with the heating target being the dielectric. In an alternating electric field, the dielectric will oscillate and then be converted into thermal energy. This is because the electric field frequency required for medium heating is very high, so the heating target must be a substance with high medium loss. Compared with other heating methods, this medium has a much faster heating speed and higher thermal efficiency.

This is because heat occurs inside the medium, and the generated heat is particularly uniform. At present, medium heating is commonly used to dry grain, heat gel, dry paper and other fiber materials. In addition, this method is also used for plastic preheating of mold costs, including rubber vulcanization and plastic bonding.

As long as the appropriate electric field frequency and device can be accurately selected, heating plywood can be completed. Only heating plywood does not heat it to the plywood itself, which is particularly convenient and reliable. In the use of hot forming, medium heating can be used for overall forging and partial forging, which is very flexible.
