One of propane's most outstanding qualities is that it is clean-burning. Since it does not leave residuals of any kind, it is highly valued in industrial processes requiring cleanliness, high energy heat and precise results. Many industries already use propane to power process furnaces, dryers, ovens and kilns.

Batch Furnaces: "Batches" of material are placed into these for processing.

Continuous Furnaces: Materials are processed constantly and move through these furnaces on a conveyor.

Direct-Fired Furnaces: This may be propane's most desired industrial use. The products of combustion come in direct contact with the materials being treated. Propane's clean burning qualities permit it to be used in direct-fired situations where less clean fuels, such as fuel oil, could produce imperfect results.

Glass Plant Furnaces: Propane is the preferred energy source in glass plants, where it is used as a fuel to power melting furnaces, annealing furnaces and tempering furnaces.

Heat Treating Of Metals: Propane gas is used for bright heat treatment of low-carbon steels, bright annealing of copper, bright brazing of steel, and steel brazing of non-ferrous metals and low-carbon steel powders.

Indirect-Fired Furnaces: In these furnaces, combustion products do not come in contact with those items being heated. These types of furnaces include enclosed muffle, radiant tube and sealed crucible.

Kilns: One of the most common propane gas industrial applications is to provide heat for all types of kilns.

Ovens: Propane also fires ovens used in core baking, curing and forming.

Process Heat Dryers: Some of these units include spray dryers, tumbler dryers, room dryers, paper dryers, conveyor dryers, rotary dryers, pan dryers and tunnel dryers
