How are Reactors Heated?

There are many ways to heat the reactor, and the specific choice depends on the nature of the reaction materials, process requirements and equipment scale. The following are some common ways to heat the reactor:

1. Jacket heating：

A jacket is set on the outer wall of the reactor, and the material in the reactor is heated by circulating heat medium (such as steam, hot water or thermal oil) in the jacket. Heating by jacket is uniform and suitable for a variety of liquid reactions. It is commonly used in large reactors in the chemical and pharmaceutical industries.

2. Internal coil heating:

A coil is set inside the reactor, and the material is directly heated by passing a heating medium (such as steam or heat transfer oil) through the coil. This heating method has high heating efficiency and precise temperature control. It is suitable for chemical reactions that require precise temperature control.

3. Electric heating:

The reactor wall is directly heated by an electric heater or an electric heating element is installed in the jacket for heating. It is simple to operate, has a fast heating speed, and is easy to control the temperature. It is suitable for laboratory or small-scale production scenarios, especially when there is no steam source.

4. Far infrared heating:

Use far infrared radiation to penetrate the kettle body and directly heat the materials in the kettle, with uniform heating and low energy consumption. It is used for chemical reactions with certain special needs and has a narrow application range.

5. Electromagnetic induction heating:

Electromagnetic induction is used to generate eddy currents in the reactor wall, directly heating the reactor wall and thus heating the material. It heats quickly, has precise temperature control, and is pollution-free. It is often used in laboratories and chemical reactions with high precision requirements.

6. Microwave heating:

Microwave radiation directly acts on the material molecules to generate heat, thereby heating the material. The heating speed is fast and the internal heating is uniform. It is suitable for special reaction processes that require fast heating or uniform heating.

Different heating methods have their own advantages and limitations, and the choice should be based on the specific process requirements. Contact pretank experts to select the most suitable reactor.
