==Summary==

[[Clinical Waste Incinerator]] operated by [[Stericycle]] ([[SRCL]]) Ltd and located at the [[Royal Oldham Hospital]]. The plant consists of a single stream, rated at 850 kilograms per hour or 7,446 tonnes per annum of solid wastes<ref name="SRCL">Annual Performance Report 2020 for SRCL Oldham Clinical Waste Incinerator</ref>. The Primary Chamber operates the [[Rotary Kiln|rotary kiln]] design to provide good mixing of the waste coupled to sufficient retention time to burn the wastes to a high quality ash<ref name="SRCL" />.

==Plant==

Waste is loaded mechanically into the Primary Chamber using a hydraulic lift and tip arrangement, to avoid any manual handling of the waste<ref name="SRCL" />. The rotating action of the kiln provides good mixing of the waste, exposing fresh surfaces to [[combustion]] conditions<ref name="SRCL" />. The [[combustion]] process is operated slightly in the [[wikipedia:Air–fuel ratio| sub-stoichiometric]] or starved air mode to produce [[wikipedia:Volatiles|volatile gases]] to fuel the Secondary Chamber while providing good burnout of the fixed carbon in the waste to produce [[IBA|bottom ash]]. The [[IBA|bottom ash]] is discharged from the end of the [[Rotary Kiln|rotary kiln]] into an ash quench system to cool it rapidly, and from the ash quench pit it is discharged into storage skips. The skips of [[IBA|bottom ash]] are taken to a [[Environmental Permit|licensed]] [[Landfill|landfill]] site for disposal as [[Non-Hazardous Waste]]<ref name="SRCL" />.

The [[combustion]] gases produced in the Primary Chamber then pass into the Secondary Chamber, which operates at a minimum temperature of 850°C during start-up using [[Non-Hazardous Waste]]; and at a minimum temperature of 1000°C when [[Hazardous Waste]] may be loaded<ref name="SRCL" />. The Secondary Chamber provides a minimum of two seconds residence time under oxygen-rich conditions to combust any [[wikipedia:Carbon monoxide|Carbon Monoxide]] and [[wikipedia:Volatile organic compound|volatile organic compounds]] produced in the Primary Chamber<ref name="SRCL" />.

The hot gases then pass through a [[wikipedia:Boiler (power generation)|boiler]] and dilution air system, which reduce the temperature from above 1000°C to around 160°C, before the gases pass on to the [[wikipedia:Scrubber|flue gas treatment]] system<ref name="SRCL" />.

The [[Flue Gas|hot gases]] then pass through a [[wikipedia:Boiler (power generation)|boiler]] and dilution air system, which reduce the temperature from above 1000°C to around 160°C, before the [[Flue Gas|gases]] pass on to the [[wikipedia:Scrubber|flue gas treatment]] system<ref name="SRCL" />.
