USER GUIDELINE FOR COAL BOTTOM ASH and BOILER …
water. When the molten slag comes in contact with the quenching water, the ash fractures instantly, crystallizes, and forms pellets. High-pressure water jets wash the boiler slag from the hopper into a sluiceway which then conveys the ash to collection basins for dewatering, possible crushing or screening, and stockpiling (Moulton 1973).
