Direct Hot Air Generators
Used for heat transfer for industrial purpses.
Direct type generators with combustion flue gas and process air mixing, equipped with thermal units fed with gaseous and/or liquid fuels. They can also be supplied with electric or hybrid thermal units.
Main areas of use: ceramic, brick, mineral and raw material processing, detergent, etc.
They can be of two categories depending on the type of burner. When the burner is of the air vein type we realize the full-crossing generator, that is, the burner body is invested over the entire section by the process air. The construction can provide for internal or alternatively external cladding.
When the burner is of the traditional type we construct a generator that provides a concentric external structure with the combustion chamber. Generally, the construction includes the inner lining of refractory material where the burner flame can develop.
Between the outer structure of the generator and the firebox we have a space for the passage of process air. The process air also has the function of “cooling” the combustion chamber both internally and externally.
At the generator end, combustion flue gas and process air mix together.
They can be designed with a horizontal axis or a vertical axis.
Indirect Hot Air Generators
Indirect type generators with separation of flue gas and process air, equipped with thermal units fed with gaseous and/or liquid fuels.
Main areas of use: food, cereal.
