Updating for Ash Cooler Fluidized Air System of a 410 …

The paper presents an updating scheme for ash cooler fluidized air system of a 410 t/h CFB boiler. The ash cooler fluidized air, which is originally designed, is provided by the independent configuration of two forced fans. By analyzing and studying the operating data of the primary air and the ash cooler fluidizing air system at various

Lower boiler load corresponds to lower air flow rate and therefore lower pressure drop through the grid. Back sifting is common in CFB boilers because the boiler load is dependent on air flow rate through the nozzles. It is also caused due to un-even distribution of fluidizing air . Primary air could pick up solids from the floor of the windbox
