The selection of thermal oil circulation heating equipment for reactor heating can refer to the following parameters:
  1. Process requirements for reactor operation;
  2. Reactor size;
  3. Reactor weight;
  4. Volume of the reactor jacket or coil;
  5. Parameters of materials inside the reactor: density, specific heat capacity, viscosity, etc.;
  6. Target temperature of materials in the reactor and the required heat-up time to reach this temperature;
  7. Inlet and outlet sizes of the reactor jacket;
  8. Whether refrigeration or explosion-proof design is required;
  9. Whether the reactor drawing can be provided.
In addition, there are two heating modes for reactor heaters.
 
One mode is to insert tubular electric heating elements directly into the reactor or arrange electric heating tubes evenly around the wall. This mode is known as the internal heating type. The internal heating type features fast temperature rise and high efficiency.
The other mode is the far-infrared electric heating device. The electric heater wraps the bottom, lower and middle sections of the reactor for heating. The far-infrared electric heating device has a large heating area, stable and rapid temperature rise, and uniform heat release. It supports convenient temperature control with segmented control at upper, middle and lower parts. The temperature of the reactor wall can be easily regulated. It has no adverse effect on the materials inside the reactor and will not cause material carbonization. It operates with low noise and low pollution, enjoys a long service life (more than 30,000 hours), and achieves remarkable energy consumption reduction (over 28%).
