Prediction of distribution of trace elements under Oxy-fuel combustion condition using Victorian brown coals

A review of oxy-fuel combustion in fluidized bed reactors

“…Roy et al comprehensively modelled the distribution of trace elements under oxy‐fuel combustion condition in a CFB using three Victorian brown coals. The amount of toxic gaseous chromium (Cr 6+ ) compound was greater for oxy‐fuel mode than for air‐firing mode for temperatures up to 1200 °C.…”

Effects of flue gas re-circulation and nitrogen contents in coal on NOX emissions under oxy-fuel coal combustion

“…CFB is a well-established boiler technology for utility-scale power generation from all types of fuels including low-rank coals. Other advantages of oxy-fuel CFB include uniform temperature distribution, small unit size, and low NO formation due to low operating temperature [10][11][12]. In general, however, N 2 O formation becomes larger at a lower combustion temperature in CFB.…”

Behavior of Pb During Coal Combustion: An Overview

“…There is a consensus in literature that a higher moisture level in the combustion chamber and flue gas can shift the equilibrium towards the formation of Pb (and other HMs) oxides, thereby suppressing the formation of chloride counterparts [28,41,54,62], which results in suppressed Pb (and other HMs) volatility. Due to the presence of H 2 O vapor in the oxy-fuel atmosphere [62], this effect can be significant during oxy-fuel combustion. It should be taken into account also if coal is co-combusted with wastes, where some of them can contain higher percentages of H 2 O (sewage sludge, agricultural residues etc.)…”
