Common Types of Process Heating Systems and Equipment

Electric Tank Heaters
External Electric Vessel Heater

In all process heating systems, energy is transferred to the material to be treated. Direct heating methods generate heat within the material (e.g., microwave, induction, or controlled exothermic reaction), whereas indirect methods transfer energy from a heat source to the material by conduction, convection, radiation, or a combination of these functions. In most processes, an enclosure is needed to isolate the heating process and the environment from each other. Functions of the enclosure include, but are not restricted to, the containment of radiation (e.g., microwave or infrared), the confinement of combustion gases and volatiles, the containment of the material itself, the control of the atmosphere surrounding the material, and combinations thereof.

Common industrial process heating systems fall in one of the following categories:
Large Heat Treated Parts
Large heat treated parts - still red-hot.
  • Fuel-based process heating systems 
  • Electric-based process heating systems 
  • Steam-based process heating systems 
  • Other process heating systems, including heat recovery, heat exchange systems, and fluid heating systems. 
The choice of the energy source depends on the availability, cost, and efficiency; and, in direct heating systems, the compatibility of the exhaust gases with the material to be heated. Hybrid systems use a combination of process heat systems by using different energy sources, or different heating methods with the same energy source.
