==Summary==

The [[Clinical Waste Incinerator]] is located at the Royal Bolton Hospital and is operated by Stericycle (SRCL) Ltd. The plant consists of a single stream, rated at 750 kg per hour or ~~6570~~ tonnes per annum of solid wastes<ref name="SRCL">Annual Performance Report 2020, SRCL Ltd</ref>. The Primary Chamber operates a [[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. The combustion process is operated slightly in the sub-stoichiometric or starved air mode to produce volatile gases to fuel the Secondary Chamber while providing good burnout of the fixed carbon in the waste to produce bottom ash,ref name="SRCL" />. The bottom ash is discharged from the end of the 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 bottom ash are taken to a licensed [[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 Carbon Monoxide and volatile organic compounds produced in the Primary Chamber~~<ref name="SRCL" />.~~
