Improving performance of CFB boiler by adopting end effect of bed exit of CFB combustor

摘要

Experiments indicate that the end effect of bed exit of CFB strongly influences the bulk density profile and internal circulation of bed materials in CFB combustor. A well designed geometry of bed exit of CFBC can create abundant internal circulation of bed materials in furnace and reduce external circulation in furnace and reduce external circulation in circulating loop of CFBC, then consequently improves comprehensive performance of CFB boiler.
