title = "PCDD/PCDF emissions from co-combustion of coal and PVC in a bubbling fluidised bed boiler",
abstract = "This paper reports on the results obtained in the study of the co-combustion of PVC with hard coal from South Africa in a 0,5 MWth Bubbling Fluidised Bed Boiler. The research has included the study of the effect of combustion temperature, fluidisation velocity and PVC content. The addition of urea to the raw fuel, as a dioxin-preventing compound has also been evaluated. Results have been analysed in terms of combustion efficiency, major pollutants emission (NOx, CO), and PCDD/Fs formation in the flue gas and in the fly ash. Under the experimental conditions tested, co-combustion of coal and PVC has proved to be feasible from the combustion efficiency and emission of PCDD/Fs points of view, whose levels remained below limits set by existing legislation on persistent organic pollutants. The addition of solid urea to the fuel blend reduces the amount of chlorinated compounds emitted. However, it has a negative impact on nitrogen pollutants formation",

note = "Funding Information: Based on the above premises, this work aims at studying PCDD/Fs emissions during co-combustion of PVC with hard coal from South Africa. The research has been carried out under financial support by an ECSC Coal RTD Project, (Project 7220-PR-108, Emissions Minimisation in Coal-Solid Waste Co-combustion by Primary Measures). Pilot scale co-combustion tests have been carried out in a 0.5 MWth Bubbling Fluidised Bed Combustor (BFBC). Rigid recycled PVC, in pellet shape, was intentionally added to South African coal just aiming to increase PCDD/F emissions in order to have a better evaluation of the extend of primary measures effectiveness (i.e. optimisation of combustion parameters and addition of inhibitor compounds). The content of PVC has ranged from 1 to 2% w/w. Funding Information: The authors wish to thank the European Commission for financial support within the ECSC Programme (Contract number 7220-PR-108).",
