	The [[Avonmouth Clinical Waste Incinerator]] is of stepped hearth design, with three main combustion hearths and an ash box. [[Healthcare Waste\|Healthcare wastes]] are loaded mechanically direct from the wheeled bins used to deliver the [[clinical Waste\|waste]], into the inspection cradle which provides the opportunity to visually inspect the [[Clinical Waste\|waste]] before it is tipped into the [[incineration\|incinerator]] charging hopper.		The [[Avonmouth Clinical Waste Incinerator]] is of stepped hearth design, with three main combustion hearths and an ash box. [[Healthcare Waste\|Healthcare wastes]] are loaded mechanically direct from the wheeled bins used to deliver the [[clinical Waste\|waste]], into the inspection cradle which provides the opportunity to visually inspect the [[Clinical Waste\|waste]] before it is tipped into the [[incineration\|incinerator]] charging hopper.

	The [[Clinical Waste\|waste]] is discharged into the loading box and is pushed from there onto the first hearth where the [[combustion\|combustion]] process commences. Hydraulic rams operate at intervals to push the [[Clinical Waste\|waste]] along the first hearth, until it falls off the end onto the second hearth where it burns vigorously at a temperature of between 850°C and 1000°C, where it burns out to produce an ash. This [[bottom ash]] and any remaining part-combusted [[Clinical Waste\|waste]] is then pushed onto the last hearths, where the fixed carbon in the ash is further burned out. The retention time of the entire process is between 4-6 hours. The residues are then dropped into an ash quench pit at the end of the process before being transferred into a skip. Ram movements are programmed in relation to the number of bins fed.

Ram movements are programmed in relation to the number of bins fed.

	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:Dioxins and dioxin-like compounds\|dioxins]] and [[Wikipedia:Furan\|furans]] produced by the [[Combustion]] process.

	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 [[Wikipedia: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:Dioxins and dioxin-like compounds\|dioxins]] and [[Wikipedia:Furan\|furans]] before discharge to atmosphere from the stack.

	The [[Clinical Waste\|waste]] is discharged into the loading box and is pushed from there onto the first hearth where the [[combustion\|combustion]] process commences. Hydraulic rams operate at intervals to push the [[Clinical Waste\|waste]] along the first hearth, until it falls off the end onto the second hearth where it burns vigorously at a temperature of between 850°C and 1000°C, where it burns out to produce an ash. This [[bottom ash]] and any remaining part-combusted [[Clinical Waste\|waste]] is then pushed onto the last hearths, where the fixed carbon in the ash is further burned out. The retention time of the entire process is between 4-6 hours. The residues are then dropped into an ash quench pit at the end of the process before being transferred into a skip. Ram movements are programmed in relation to the number of bins fed.

	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.
