In 1855, Robert Bunsen originated the concept of using liquified petroleum gas, propane, or methane. While this caused the production of the Bunsen burner for use in labs, tons of factories and businesses quickly adopted this in the form of an industrial gas burner. Presently, these gas burners are often found in the following forms (but not limited to):
These are primarily used in heating tanks utilized by food-making, ceramic, and textiles industries. Their simple design enables a stable stream of flame that can heat up the contents of the tank evenly. They can even integrate air mixers to help control the flame, especially if the flame's temperature has to be modulated precisely. Other applications for pipe burners involve preheating, salt bath stripping, and even cleaning the very same tanks they heat.
A nozzle burner has two unique advantages over a lot of industrial gas burners. First, it is self-sufficient enough to generate a flame that doesn't require compressors or air mixers. Second, it is reasonably tiny enough to be carried and operated by one man, and can carry out a myriad of duties in a factory like singeing, annealing (modifying the properties of a material by burning it) and smelting.
Its main function is for metal and glass melting, specifically if only certain areas of the metal or glass needs to be heated. However, it can also be made use of in repairing molds and furnaces by burning away left-over or excess materials that were poured on them. This process requires a two-man team and severe precision that only a nozzle burner can provide.
Factories employ this scaled-up version of the kitchen stove for boiling, micro brewing and of course food processing. This exact same technology can similarly be seen in a standard kiln burner used in forming ceramics and pottery. So-called multi-ring burners also exist as even larger versions of the ring burner.
Essentially, industrial gas burners are larger and more advanced variations of Bunsen's technology. Their different configurations just goes to prove that gas burners have a vast range of uses beyond the cooking area or lab.
