Reducing Ash Agglomeration in JEAs CFB Boilers

Oct 01 2012 · A chronic operational problem with circulating fluidized bed boilers is ash buildup or agglomeration that turns into slag which forces frequent shutdowns for cleaning.

Ash deposition behavior of a high-alkali coal in ...

High alkali and alkali earth metals (AAEMs) content in coal causes severe slagging and fouling during combustion in a boiler. In this study the ash deposition behavior of a high-alkali coal at different bed temperatures and the effect of kaolin were investigated in a 30 kW circulating fluidized bed (CFB) test system using an ash slagging probe and deposition probe.

Study on the Deposits Derived from a Biomass Circulating ...

Biomass tends to form deposits and tends to slag during combustion. This study focused on deposits obtained from a circulating fluidized bed (CFB) in a biomass power plant. Analyses using scanning electron microscopy energy-dispersive spectrometry and X-ray diffraction are also included. The results indicate that the deposits are dense with a certain hardness which resulted from the erosion ...
