Abstract
Used fiber and plastic based packaging have high heat values if combusted. The aim of this research project was to investigate the usability of different types of packaging waste as a secondary fuel of circulating fluidized bed boiler (CFB). The effect of limestone addition was also investigated. The tests were carried out in a 65 MW Pyroflow boiler at Kauttua. The main fuel during the tests was a combination of peat and coal. The packaging wastes were mixed board and flexible packaging material (production waste), liquid packaging board (production waste), mixed plastics (post-consumer waste) and RDF (refuse-derived fuel, which was post-consumer waste containing plastics, paper and board). The share of these co-fuels varied between 8-20 % of the thermal input. The co-fuels performed well and the combustion was effective in all tests. NO{sub x} emissions in all tests were below the allowed maximum level of a new power plant. SO{sub 2} emissions in co-fuel combustions were lower than the allowed maximum level of a new power plant in Finland. The chlorine from co-fuels gave an increase in HCl emissions, but when limestone was used, chlorine was mostly bound to fly ash. The polychlorinated dioxin and furan (PCDD/F) emissions in the
