Industrial Electric Melt Blown Pipeline Heater

1.Electric Heating Principle

Resistance Heating: When an electric current passes through the resistance wire, heat is generated according to Joule's law. ?Then, the heat is transferred to the pipeline in a conduction manner through the insulating and heat-conducting material, thus increasing the temperature of the fluid inside the pipeline.

Electromagnetic Induction Heating: An alternating current is passed through the coil to generate an alternating magnetic field. ?This makes the pipeline generate an induced electromotive force. ?Heat is generated by utilizing the resistance of the pipeline itself. ?The heating power can be controlled precisely by changing parameters such as the number of turns of the coil and the magnitude of the current.

2.Steam Heating Principle

Steam flows inside the pipeline heater. ?The heat is transferred from the steam side to the fluid inside the pipeline through the pipeline wall in a conduction manner. ?After releasing heat, the steam condenses into water. ?A steam trap device is required to discharge the condensed water in a timely manner to prevent any impact on heating and the occurrence of water hammer.

3.Heat Transfer Oil Heating Principle

The heat transfer oil is heated in the heating furnace and then sent to the pipeline heater by a circulating pump. ?It exchanges heat with the fluid inside the pipeline. ?Due to its high specific heat capacity and good thermal stability, the heating power can be precisely controlled by adjusting the flow rate and temperature of the heat transfer oil.

4.Hot Air Heating Principle

The fan sends air into the heating device to form hot air. ?The hot air is then sent to the surroundings or inside of the pipeline to be heated through pipelines. ?The heat is transferred to the pipeline and the fluid inside it in a convection and radiation manner. ?It has the characteristics of fast heating and uniform temperature.
