UTILIZATION OF CLARIFIED WATER FROM THE HYDRAULIC ASH DISPOSAL SYSTEMS AT A THERMAL POWER PLANT.

Clarified water from closed hydraulic ash removal systems may be used to seal dredge pumps, for washing the ash rooms of coal dumps, for treating coal dumps and ash dumps for dust and for irrigating fly-ash scrubbers. This use can eliminate excess water and, along with natural water losses at ash dumps, it will provide a water balance to most recycle hydraulic ash removal systems. In order to enhance the work reliability of fly-ash scrubbers using clarified water, it is necessary to replace the standard nozzles and jets with ones that are specially adapted for use with scale-forming water.
