1. Introduction
The chlorine chemistry in combustion and gasification of solid fuels is a concern, partly due to the possibility of pollutant emissions and partly due to the corrosive potential of chlorine. In particular annual biomass and certain waste fractions may contain chlorine in significant quantities [1]. Chlorine is typically released during pyrolysis as chlorinated hydrocarbons (e.g., chloromethane, CH3Cl), hydrogen chloride (HCl) or alkali chloride (mainly KCl). During combustion the chlorine will largely be oxidized and emitted as HCl. Hydrogen chloride is typically the desired chlorine containing product in combustion, because it can easily be removed from the flue gas by a scrubbing process. However, chlorine is known to participate also in dioxin/furan formation through mechanisms that may involve high-temperature gas phase reactions as well as low-temperature reactions catalyzed by fly ash [2–4].
