What a Pneumatic Conveying System is
The principle of pneumatic conveying is based on the fact that bulk goods can be moved by means of air through pipelines. The flowing conveying air transmits a propulsion force on the bulk material and thus conveys it through the conveying line. The pneumatic conveying always requires a pressure difference between the beginning and the end of the pipeline. To overcome this pressure difference, conveying blowers or compressors are used.
The height of the pressure difference to be applied depends not only on the length and layout- the isometry – of the conveying line but also on the concentration of the bulk material in the conveying line – the loading. The pneumatic conveying methods can be distinguished in terms of their loading in lean phase, strand phase and dense phase conveying.
Generally, one differentiates between suction and pressure conveying systems and the combined suction pressure conveying systems.
Historically, the first pneumatic conveyor systems were created in connection with the discharge of grain from overseas ships. Later, this new technology of continuous development spread into other process engineering areas.
Today’s special applications are:
Pneumatic Conveying
Burner feeding with combustible dusts and alternative fuels in the cement industry
Feed lance injection and pneumatic transport feeding in the area of Steelmaking FE and non-ferrous iron-metal smelting
Pneumatic conveying in the recycling sector
Injection of alternative fuels in fluidized beds at power plants
The transfer of powders, granules, flakes and other dry bulk solids materials through enclosed convey lines utilizing air, which is typically generated from a fan or blower.
