Coal-water Slurry Fuel. 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 ...


Coal-water slurry fuel (CWSF) is economically viable provided that its ash content does not exceed 30% and the amount water in the fuel is at most 45%. Two impoundments were revealed that have considerable reserves of waste coal useful for commercial manufacture of CWSF without the beneficiation step. One of the CWSF manufacture steps is the comminution of coal sludge to have a …

OSTI.GOV Journal Article: Vibration mills in the manufacturing technology of slurry fuel from unbeneficiated coal sludge


A process for producing a coal-water slurry having a high coal concentration (generally 60 to 80% by weight or more) and a lower viscosity, at a lower cost and with a smaller amount of dispersing agent added is provided, which process is directed to a process for producing a high concentration coal-water slurry by feeding coal, water and a dispersing agent into a wet, continuous ball mill and ...


To obtain proper granulation of solid phase, coal-water slurry was prepared in two-stage milling process in wet conditions. Preliminary crushed coal, after sieving process has been crushed in a ball mill with water addition and then was direct - ed to the rod mill in order to obtain final granu-lation. The solid phase concentration of 67–70%


However, even at the highest slurry density, the product size distribution was steeper than the broad size distribution recommended for maximum solids loading and minimum viscosity. Additional grinding tests were performed in a stirred ball mill, aiming at a two-stage grinding method for …


Coal Mill Of The Coal Water Slurry Malawi. Water coal slurry as an alternative to natural gas and . Among the many existing methods of coal crushing, the continuous wet grinding ball mills are the most widely used at this time coal, crushed to particle size of mm, is fed into ball mills for further pulverization, along with water and additive the ball mill crushes the coal to.


The objective of this research is the development of improved technology of the preparation of coal-water slurries that have potential for replacing fuel oil in direct combustion. Research accomplishments are summarized for: standardization of experimental procedures; investigation of effect of high-pressure roll mill/ball mill grinding on the energetics of fine grinding and the rheology of ...
