Slurry transport
Slurry transport uses several methods: hydraulic conveying; conventional lean slurry conveying; and high concentration slurry disposal (HCSD). The latter, HCSD, is a relatively modern approach, which is used to transfer high throughputs of fine fly ash over long distances (>10 km or 6.2 mi) using high pressure diaphragm pumps with velocities of around 2 m/s.
