Sulfur evolution from coal combustion in O2/CO2 mixture

Sulfur behavior during coal combustion in oxy-fuel circulating fluidized bed condition by using TG-FTIR

“…Zheng and Furimsky [3] also predicted that the combustion atmosphere had no influence on SO 2 formation by FACT simulation. Duan et al [8] revealed that more SO 2 released in O 2 /CO 2 atmosphere, which might be attributed to the activated C/S/CO 2 reaction.…”

“…But up to now, there are less studies on coal pyrolysis in oxy-fuel condition, especially for oxy-fuel CFB combustion. Duan et al [8], Rathnam et al [15], and Naredi and Pisupati [16] all investigated the coal pyrolysis in oxy-fuel condition recently, but they were more interested in pyrolysis characteristics than evaluations of gaseous pollutions. So it necessitated an investigation of coal pyrolysis for deeper insight into the sulfur evolution in oxy-fuel CFB condition.…”

A study on municipal solid waste (MSW) combustion in N2/O2 and CO2/O2 atmosphere from the perspective of TGA

“…Sheng et al [12] found that O 2 /CO 2 combustion did not significantly change the mineral phases formed in the residue ashes, but did affect the relative amounts of the mineral phases. Duan et al [13] argued that replacing N 2 with CO 2 increased SO 2 releasing rate. SO 2 emission increased first and then decreased as O 2 fraction increases in the O 2 /CO 2 combustion.…”

Combustion behaviour of Turkish lignite in O2/N2 and O2/CO2 mixtures by using TGA–FTIR

“…There exists a considerable number of studies carried out for the investigation of combustion behaviour high rank coals in oxy-fuel environment by TGA [8][9][10][11][12][13]. However, an investigation of oxyfuel combustion characteristics of indigenous lignites by TGA-FTIR technique is not available to date.…”
