Clinical Waste Incinerator operated by Stericycle (SRCL) Ltd and located at the Royal Oldham Hospital.
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 7446 tonnes per annum of solid wastes[1]. The plant consists of a single stream, rated at 850 kilograms per hour or 7446 tonnes per annum of solid wastes. The Primary Chamber operates the rotary kiln design to provide good mixing of the waste coupled to sufficient retention time to burn the wastes to a high quality ash[1].
Plant
Waste is loaded mechanically into the Primary Chamber using a hydraulic lift and tip arrangement, to avoid any manual handling of the waste[1]. The rotating action of the kiln provides good mixing of the waste, exposing fresh surfaces to combustion conditions[1]. 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. 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 dispsoal as Non-hazardous Waste[1].
