Balancing Analysis of Charges of Circulating Fluidized Bed Boilers

The paper presents theoretical analysis and study results on the charge balancing problem of circulating fluidized boilers (CFB). CFB boiler charges can be distinguished into bottom slag, fly ash, internally circulating charge and externally circulating charge. Balancing of charges that enter internal circulation at the furnace's upper part constitutes the operational foundation of CFB boilers. It is important for operation to figure out the amount of charge that partakes in the internal circulation.
