TUYERE INJECTION:

A technique has been developed at Avonmouth for injecting fine dust into the bottom of the Imperial Smelting Furnace (ISF). This was developed initially to feed back to the furnace fine drosses which previously had to go back to the beginning of the process - the sinter plant.

The technique was successful enough to develop a custom built pneumatic handling, storage and injection facility to deal with similar fine materials.

Fine dusty materials have always presented an environmental problem during handling and often the only solution was to treat the dust with water to make it acceptable.

The Tuyere Injection process is designed to handle the dusty materials directly without further treatment. The dusty waste is ideally brought to site in road tankers which feed directly into a storage silo ready for Tuyere Injection.
