A jet furnace is an industrial furnace with high-velocity gas jets (generally, combustion gases or air-fuel mixtures) that can be used to heat metal surfaces rapidly. The high speed of the jets implies higher heat transfer efficiency or uniformity.

Key Features:

• Function: Jet furnaces provide localized, directed heat, heating rapidly while using the burner controls to manage heat delivery.
• Process: The turbulence created by being immersed in gas streams increases the heat penetration into the metal and causes the heat to reach its target faster, which is often the goal of production.
• Application: Jet furnaces are used in steel reheat operations, forging, and heat treatment processes where you want to deliver fast, even heat.

Jet furnaces are highly regarded for their efficiency, speed, and temperature control. Even with multiple jetted thermocouples, jet furnaces can reduce heat-up time while consuming reduced fuel usage rates. An ideal application would be a high-volume industrial setting (i.e., rolling mills, metallurgical plants, etc.) where the requirement is to maintain product consistency throughout the thermal processing required.
