The [[flue gases]] from the [[Incineration]] process then pass through a secondary chamber, or afterburner, where any gaseous products of [[Combustion]] are burned out under oxygen rich conditions. This stage is designed to destroy any [[Wikipedia:Carbon monoxide|Carbon Monoxide]], [[Wikipedia:Volatile organic compound|Volatile Organic Compounds]], and [[Wikipedia:Dioxin|dioxins]] and [[Wikipedia:Furan|furans]] produced by the [[Combustion]] process. [[Wikipedia:Ammonia|Ammonia]] in the form of [[Wikipedia:Urea|urea]] solution is injected into the secondary chamber for further control and reduction of [[Wikipedia:Nitrogen oxide|oxides of nitrogen]] emissions. | The [[flue gases]] from the [[Incineration]] process then pass through a secondary chamber, or afterburner, where any gaseous products of [[Combustion]] are burned out under oxygen rich conditions.

The [[flue gases]] are then cooled by passing through a waste-heat boiler and economiser, before passing into the final, abatement section of the process. Powdered [[Lime (material)|lime]] (Calcium Hydroxide) and powdered [[wikipedia:Activated carbon|activated carbon]] are added to the flue gases entering the abatement process to remove acid gases, heavy metals and residual [[Wikipedia: | The [[flue gases]] are then cooled by passing through a waste-heat boiler and economiser, before passing into the final, abatement section of the process.
