Coal-water slurry fuel - Wikipedia

Coal-water slurry fuel was made in a ball mill which pulverised the coal or coal sludge. This was done near a coal mine in Belovo, Siberia. The coal-water slurry fuel was transported through a pipeline to Novosibirskaya TEC-5, Novosibirsk, a distance of 262 km (163 mi). The pipeline had three intermediate pumping stations.Louis Wibberley - CSIRO Dave Osborne Somerset,Micronized Coal Water Slurry •Coal tailings sources •Including tailings impoundments •Increased grade recovery •Recovery of ultra fines •Minimal dewatering •Road/rail/ship –cake or slurry •Pipeline coal water fuels •Higher solids paste for longer distance •Mine-mouth orThickening of ultrafine coal-water slurries in a solid,,OSTI.GOV Conference: Thickening of ultrafine coal-water slurries in a solid-bowl centrifuge Title: Thickening of ultrafine coal-water slurries in a solid-bowl centrifuge Full Record
