Submerged Chain Conveyor System (SCC System)

Submerged Chain Conveyor System (SCC System)

The SCC is a system developed by Germany's Babcock Borsig AG and extensively used for coal-fired thermal power mainly in Europe.

Feature

  1. This system utilizes water seal which reduces no waste water under normal operation.
  2. This system is compact in comparison with the hydraulic conveying system.
  3. This system can handle mill pyrite.

Handling System

Bottom ash goes through a transition chute and drops to the upper trough of the Submerged Chain Conveyor (SCC). It is rapidly cooled and conveyed continuously to the outlet slope by a scraper. After dehydration at the slope, bottom ash is crushed and conveyed to a storage bin by a belt conveyor.

Cooling water flows to a circulating tank through the SCC trough and goes through a heat exchanger to comes back to the SCC.
