A Mechanism of Inhibition of CaO-SO2 Reaction during Fluidized Bed Sludge Incineration

Prevention of bed agglomeration with iron oxide during fluidized bed incineration of refuse-derived fuels

“…We used the Gibbs free energy minimization method and the extensive thermochemical database of HSC Chemistry [8], which contains the enthalpy (H), entropy (S), and heat capacity (C) data for more than 17,000 chemical compounds. This model has been used to estimate the equilibrium compositions of chemical compounds at high temperature by several researchers [9][10][11][12]. The model calculated the amounts of the Na 2 O·2SiO 2 , Na 2 O· SiO 2 , and K 2 O·4SiO 2 melts that contributed to agglomeration [1,13], so that the potential for bed agglomeration could be predicted.…”

“…Several researchers have reported that Na component has a higher affinity for P component than for Si component, and that the reactivity of P component for Ca component is higher than for other ash compounds [11,12]. RDF 1 has a higher P component content than palm fiber but it also has a high content of Ca component.…”

Porous Ca-based bead sorbents for simultaneous removal of SO2, fine particulate matters, and heavy metals from pilot plant sewage sludge incineration

“…Conventional technologies used for desulfurization employ wet and semi-dry scrubbers that use Ca-based sorbents [10][11][12]. Generally, Ca-based sorbents are widely used for in situ SO 2 capture in dry fluidized-bed combustion.…”
