No Maintenance Pneumatic Conveying for the Power Industry
Fox Venturi Eductors have been used since the 1960’s to provide reliable, maintenance-free conveying of fuels, sorbents, additives, ash, dried sludge, and other many other solids when 24/7 reliability is required.
Dozens of Power Producers, Incinerators, Cement Kilns, and Cogen Plants since 1977 have used Fox eductors to reliably convey material to or from their combustion processes.
Where are they used? What are they conveying?

Injecting Alternative Fuels, RDF, and Waste into Boilers, CFB’s, and Kilns with No Moving Parts
Fox Venturi Eductors have conveyed every conceivable type of BTU-containing fuel into combustion processes, including crushed and pulverized coal, coke, and dozens of various waste products like sawdust, shredded carpets, rice hulls, crushed seeds, and paper scrap.
Venturi eductors do not convey with least possible amount of conveying air, so if minimizing conveying air use is paramount, other methods must be considered. However, if reliability is a paramount concern, then Fox eductors must be looked at. Highly abrasive products such as dried sludge, soybean hulls, and other silica-rich biomass all wreak havoc with rotary airlocks and screw conveyors. All have been conveyed reliably with Fox ceramic-lined eductors. Dried sludge in particular has disintegrated a number extremely expensive dense phase and airlock conveying systems (request our published case history about the City of Los Angeles.)
