Plant Description
During 2024 the plant moved to a repackaging and transfer operation while the existing incinerator underwent major refurbishement works.
The incinerator has a design capacity of 650kg/h with a typical operating capacity of ~510kg/h. The incinerator is fitted with air pollution control comprising of lime injection (to control emissions of sulphur dioxide and hydrogen chloride) and activated carbon (to control emissions of heavy metals and dioxins).
There is also a high efficiency bag filtration system for the removal of particulate matter [1].
There is a secondary combustion chamber that provides the required residence time of more than 2 seconds at a temperature of at least 850°C and 1000°C for cytotoxic wastes.
Natural gas is used to support the combustion and to maintain the secondary temperatures.
Emissions to air are discharged via a 70-metre stack. There is an energy recovery system, and the incinerator supplies hot water to the adjacent hospital.
Solid wastes produced are primary bottom ash and residues from the air pollution control system.
