Coal-water slurry fuel - Wikipedia

Belovo Novosibirsk project. In the late 1950s, the Soviet Union looked for new methods of using coal sludge for power generation. 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).
