Process Furnace employing combustion produce a hot gas that transfers heat to the material by radiation and convection. Solids are heated by direct contact, but fluids are usually heated indirectly, being carried inside pipes within the furnace. The second is that of furnaces designed to heat process fluids other than water.

Process furnace heaters are used to maintain heat within a liquid medium like water, oil and different chemicals along with stabilizing the gas. This process is carried out in a very careful way as a single glitch might result in drastic outcome. Another name of these types of heaters is fired heaters.
