DEVELOPMENT AND APPLICATION OF AN INNOVATIVE DRY BED ASH EXTRACTION SYSTEM FOR FLUIDIZED BED COMBUSTION BOILERS

摘要

The innovative Fluimac system for Fluidized Bed Combustion Boilers allows the extraction and cooling of the Bed Ash; overcoming the main drawbacks of conventional system such as mechanical wear, maintenance cost and loss of ash heat content. The Ash is extracted and conveyed by the Superbelt steel belt conveyor and cooled by the counter-flow air. A Fluimac installation on the 340 MW_e Yeosu#2 Power Plant (South Korea) started its operation on July 2011 and confirmed expected targets.
