The cоmbustiоn оf chlorine-beаring fuels cаn result in the formаtion of dioxins, highly toxic pollutants. On the other hand, sulfur in fuel mitigates the formation of dioxin. A rule-of-thumb for preventing dioxin formation is to maintain a sulfur-to-chlorine (S:Cl) molar ratio greater than one for fuel mixtures to be burned. Determine whether dioxin emissions might be expected from the combustion of hybrid poplar wood chips. Determine the maximum mass fraction of hybrid poplar wood that can be blended with bituminous coal in a fuel blend to avoid dioxin emissions. What is the HHV of the blend (determined in (B)) in units of MJ/kg dry It is recommended that fuel alkali content should not exceed 0.34 kg/GJ to prevent ash fouling in combustion systems. Is the above blend (determined in (B)) likely to cause ash fouling? What is expected sulfur emission rate (kg/GJ) for the fuel blend (determined in (B))?
