Type and setting mode of electric heater of reactor

Everyone should know the electric heater of the reactor, but its classification may be relatively unfamiliar. For now, the electric heater of the reactor can be divided into three types. The heating position of each type will be different. The effect is also different. Which three are there?

One is to use a flange-type tubular reactor electric heater. Its electric heating element is inserted in the jacket of the reactor to heat the heat transfer oil, which can effectively transmit the heat energy to the chemical raw materials in the reactor to achieve the required The temperature meets the requirements of the reaction.
