Reducing Ash Agglomeration in JEA's CFB Boilers

1.19.2.3 Technical Challenges in Combustion or Co-Combustion of Biomass. Bed agglomeration is the one of the major problems during the combustion of biomass, which could cause partial or complete bed de-fluidization, and as a result, unscheduled plant shutdown. Fig. 2 shows the schematics of two possible mechanisms of bed material agglomeration.

1/12/1998 · Technol. Experiments have been done subjecting ashes from industrial-scale FBC boilers to sulphating conditions in an oven for up to 105 days. These show that sulphation by itself causes agglomeration in the virtual absence of V, K, and Na, the elements normally associated with ash softening and classical fouling.
