The Ashford plant [[Incineration|incinerates]] [[Clinical Waste|clinical waste]], including [[Clinical Waste|clinical wastes]] classed as [[Hazardous Waste|hazardous]] under the [[Hazardous Waste (England and Wales) Regulations 2005]]. The bulk of the [[Clinical Waste|waste]] is produced at hospitals, but also includes smaller quantities from doctors’ surgeries, dentists, health clinics, residential and nursing homes, and from medical research facilities. The [[Hazardous Waste|hazardous wastes]] [[Incineration|incinerated]] include infectious waste and waste containing cytotoxic or cytostatic medicines. The plant also [[Incineration|incinerates]] small amounts of specialised wastes where it is recognised that [[High Temperature and Clinical Waste Incineration|high temperature incineration]] represents the best [[Disposal|disposal]] option.

The [[Incineration|Incinerator]] is designed to process 1000 kilograms per hour. The [[Incineration|incinerator]] is of stepped [[Grate|hearth]] design, with three main [[Combustion|combustion]] [[Grate|hearth]] and an [[Incinerator Bottom Ash|ash]] box. [[Healthcare Waste|Healthcare Wastes]] are loaded mechanically direct from the wheeled bins used to deliver the [[Clinical Waste|waste]].

The [[Clinical Waste|waste]] is charged onto the first [[Grate|hearth]] where the [[Combustion|combustion]] process commences. Hydraulic rams operate at intervals to push the [[Clinical Waste|waste]] along the first [[Grate|hearth]], until it falls off the end onto the second [[Grate|hearth]] where it burns vigorously at a temperature of between 850°C and 1000°C, where it burns out to produce an [[Incinerator Bottom Ash|ash]]. This [[Incinerator Bottom Ash|bottom ash] and any remaining part-combusted [[Clinical Waste|waste]] is then pushed along the [[Grate|hearth]], where the fixed carbon in the ash is further burned out. The residues are then dropped into an [[Incinerator Bottom Ash|ash]] pit the end of the process.

The [[Flue Gas|flue gases]] from the [[Incineration|incineration]] process are passed through a secondary chamber, or afterburner, where any gaseous products of [[Combustion|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:Dioxins and dioxin-like compounds|dioxins]] and [[Wikipedia:Furan|furans]] produced by the [[Combustion|combustion process]].

The [[Flue Gas|flue gases]] are then cooled by directing them through a waste-heat boiler before they pass into the abatement section of the process. Powdered [[Wikipedia:Lime (material)|lime]] and powdered [[Wikipedia:Activated carbon|activated carbon]] are added to the [[Flue Gas|flue gases]] entering the abatement process to remove acid gases, [[Wikipedia:Heavy metals|heavy metals]] and residual [[Wikipedia:Dioxins and dioxin-like compounds|dioxins]] and [[Wikipedia:Furan|furans]] before discharge to atmosphere from the stack. The [[Flue Gas|flue gases]] being discharged from the [[wikipedia:Chimney|stack]] are continuously monitored.

The [[Incineration|incineration]] process produces two residues; [[IBA|bottom ash]] and [[APC Residues|spent lime]].
