Flue Gas - an overview | ScienceDirect Topics

Flue gas (sometimes called exhaust gas or stack gas) is the gas that emanates from combustion plants and which contains the reaction products of fuel and combustion air and residual substances such as particulate matter (dust), sulfur oxides, nitrogen oxides, and carbon monoxide (Table 3.7).When burning coal and/or waste materials, hydrogen chloride and hydrogen fluoride may be present in the
