Coal amp Water Mixture Replaces Fuel Oil

Coal amp Water Mixture Replaces Fuel Oil

The mixture is manufactured by crushing coal to the point that 80 to 90 percent of it will pass a no. 200 screen. the crushing process is carried out in a wet ball mill, because of safety (coal dust is highly explosive) and as the first stage in a final slurry consisting of 60 to 70 percent coal fines in 30 to 40 percent water, by.The purpose of filtration apparatus 26 is to separate some of the water from the coal-water portion from pipeline 20 so that, when the wet solids from apparatus 26 are recombined with the slurry in pipeline 20, the resultant weight percent of coal in the pipeline mixture entering grinding apparatus 20 will be increased and will vary from 60-70.

Process For Producing High Concentration Coal

Process For Producing High Concentration Coal

Then, as the coal finely pulverized in this ball mill and the remainder (20%) of the above mentioned coarsely crushed coal were mixed, the resulting mixture was fed into and finely pulverized in a wet-type ball mill to prepare a high-concentration coal-water.Then, the coal was flushed into an oil phase or agglomerated with oil and surfactant. the flushing and oil agglomeration processes resulted in an ash content decrease from 7. 2 to 4. 1 and 2. 2 wt% respectively. moreover, oil agglomeration decreased the water content of coal from 4. 61 to 2. 0.
