Sep 28, 2018· Traditionally, bottom ash removal is based on a simple system design that uses hoppers and crushers under a furnace and a sluice system that conveys the ash to a surface impoundment or dewatering system. Compliance with CCR and ELG means bottom ash transport water can no longer be discharged — a closed-loop system.

Jan 24, 2018· Ash conveyor systems designed specifically for conveying hot, abrasive ash such as bottom ash or fly ash from boiler beds, bag houses, or electrostatic precipitators. These systems …

ASH HANDLING SYSTEM: Boilers burning pulverized coal (PC) have bottom furnaces. The large ash particles are collected under the furnace in a water-filled ash hopper, Fly ash is collected in dust collectors with either an electrostatic precipitator or a baghouse. A PC boiler generates approximately 80% fly ash and 20% bottom ash.
