Pneumatic Conveying of Pulverized Fuel Ash

Pneumatic Conveying of Pulverized Fuel Ash

Power Gen PLC of Retford, England rely on Macawber engineering at their Cottam Power Station (4×500 MW) to replace an existing fly ash handling system. The Macawber AshVeyor® System was installed on unit #2 to continuously convey pulverized fuel ash (P.F.A.) over a distance of 560 feet.
