摘要： PURPOSE: To prepare a coal/water slurry of high concentration, low viscosity and low ash content, by crushing raw material coal into a plurality of ground coals having different particle size distributions, deashing them separately and blending the refined coals.
CONSTITUTION: In the preparation of a coal/water slurry of high concentration, low viscosity and low ash content in which raw material coal is crushed, classified by particle diameter and deashed, a plurality of ground coals with different particle size distributions are produced by crushing the raw material coal in coarse, medium and fine sizes. The ground coals are deashed separately into refined coals, which are classified by particle diameter. The refined coals are blended for adjustment of particle diameter and made into concentrated aqueous slurry of coal. Although a larger maximum particle diameter and a wider range of particle diameter distribution afford a higher concentration of slurry, coal particles with a diameter of 300μm or larger are difficult to burn and therefore the maximum particle diameter of adjusted coal should be 300μm at largest.

摘要： PURPOSE:To permit the removal of harmful components contained in dust-rich waste gas by passing the waste gas through a large number of parallelized and channeled spaces opening at both ends inside an adsorbent-packed layer. CONSTITUTION:Cone-shaped long members 6 are aligned at equal intervals 8 and in parallel inside a packed layer 1 filled with an adsorbent, e.g., activated carbon, etc. The, staggered pipes groups of the same material 6 are arranged below the cone-shaped long members 6. Then, all adsorbent is drawn out of the lower part of the packed layer 1 and then moved downwards to form channeled spaces 5. When a gas is let in the front net 11 of such a packed layer 1, it flows into the spaces 5 in an incoming gas low 14 and goes out from the opening of the rear net 12 side in an outgoing gas flow 15. Dust present in the gas goes straightforwards with the gas without deposition. On the other hand, SO2, etc., for example, present in the gas is adsorbed on the adsorbent and drawn out of the lower part of the packed layer 1.
