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. | 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 (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:Dioxin|dioxins]] and [[Wikipedia:Furan|furans]] before discharge to atmosphere from the stack. The flue gases being discharged from the stack are continuously monitored for [[wikipedia:Hydrogen chloride|Hydrogen Chloride]], [[wikipedia:Sulfur dioxide|Sulphur Dioxide]], [[Wikipedia:Carbon monoxide|Carbon Monoxide]], [[Wikipedia:Nitrogen oxide|Oxides of Nitrogen]], particulate matter (dust), [[Wikipedia:Volatile organic compound|Volatile Organic Compounds]], [[Wikipedia:Oxygen|oxygen]] and [[Moisture Content|moisture content]]. | 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.

The [[Incineration|incineration]] process produces two residues; bottom ash and spent lime. The bottom ash is sent to a recycling transfer station for reprocessing, the bulk of the material ultimately ending up as a [[Landfill|landfill]] cover material. The spent lime, which is the residue from the flue gas abatement process, went to a site in Leeds where it is used to neutralise acidic wastes. | The [[Incineration|incineration]] process produces two residues; bottom ash and spent lime.
