Reactivation of limestone sorbents in FBC for SO2 .

01.04.2007 · 1. Introduction. Sorbent reactivation has received attention for over 25 years, and, even earlier, hydration of calcined limestone had been shown to improve its performance as a sorbent for sulphur dioxide at fluidized bed combustion (FBC) temperatures .However, even now reactivation by hydration is still not a routine process for FBC boilers firing high-sulphur fuels.

Impact fragmentation of limestone-based .

Two sorbents were used in this investigation: i) a German limestone, termed "EnBW" and ii) an Italian limestone, termed "Massicci". Previous studies demonstrated that these sorbents are characterised by fairly high and poor reactivities, respectively. This is related to the different pore size structure of the two materials (more favourable for EnBW), whereas they are characterised by ...

the sorbent contents of 1% and 3% with the CaCO3 and Ca(OH)2 contents of limestone and hydrated lime sorbents are illustrated in Figures 1 and 2. The experimental results obtained for the sulfation reactions performed at 323 K clearly showed a strong dependence between the total sulfation capacities of slurries and CaCO3 and Ca(OH)2 content of the sorbents and following empirical equations ...

Influence of Sorbent Characteristics on Fouling .

Sorbent limestone is used widely in CFB boilers effectively to control sulfur dioxide emissions. Hard deposits were formed in backpass of CFB boiler while using high sulfur Indian lignite and limestone sorbent to control SO 2. In addition large quantum of loose deposits caused severe blocking of the second pass. Unreacted calcium oxides that settled on heat transfer tubes at temperature ...

Controlling So2 Emissions: a Review of Technologies

A diverse group of wet FGD processes have evolved to take advantage of particular properties of various sorbents and/or by- products. All wet FGD processes discussed here are once-through (i.e., non-regenerable). A generalized flow diagram of a baseline wet FGD system is shown in Figure 2-2. SCVcontaining flue gas is contacted with limestone slurry in an absorber. Limestone slurry is .
