COAL PREPARATION

TABLE 7-14. Effect of Geometry and Concentration of Feed Solids on throughput

for a 1/6-in, diam hydro cyclone cleaning 1/4-in

Varying the distance between the bottom of the vortex finder and the hydro cyclone

cone bottom. For example, the washed coal ash can be reduced by decreasing the diameter

of the vortex finder, decreasing the length of the vortex finder, or increasing the diameter

of the underflow orifice. Increasing feed-Solids content increases the specific gravity of

separation and, therefore, washed coal yield and ash, which indicates the importance of

maintaining a constant feed-solids content to preserve washed coal quality.

Capacity is influenced by cyclone geometry, i.e., the sizes of the overflow,

underflow, and inlet openings, and by feed-solids content. The effects of these parameters

is given in Table 7- 14.Increasing inlet pressure is a simple method of increasing capacity

without changing hydro cyclone geometry, and washed yield and ash are not significantly

affected. However, the penalty is increased pumping cost, and degradation of the coal.
