A novel reactor reproducing PCB (pulverized coal boiler) environment was used to evaluate the potential of sorbent co-firing and waste co-combustion as cheap retrofitting techniques to reduce SO2 emissions of existing boiler. Several co-feeding tests of coal and CaCO3 and coal and Ca(OH)2 have been performed for a gas residence time around 0.5 s (4 times shorter than PCB). Results show sulfur emission...
The effect of co-combustion of Refuse Derived Fuel (RDF) with Korean anthracite on the combustion and environmental performance was observed in the Tonghae commercial Circulating Fluidized Bed (CFB) boiler. High contents of oxygen and CaO in RDF reduced the amount of air required for combustion and the limestone flow rate for SO 2 capture in the CFB boiler, respectively. The temperature in...
Energy recovery from refuse derived fuels (RDF) and packaging derived fuels (PDF) is one option in integrated waste management. Nine RDF and PDF co-combustion tests with peat and coal in a circulating fluidized bed boiler were carried out in this work. Heavy metal emissions in flue gas and fly ash were measured. Multivariate data analyses were used to find out the most important parameters affecting...
Refuse derived fuel (RDF) has been burned with wood chips and milled peat in a 4 MW bubbling fluidized bed boiler. Emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/F) in flue gases expressed as TCDD -equivalents were significantly below the emission limit 0.1 ng/m 3n I-TEQ (11 % O 2 ). Also the PCDD/F -concentrations of fly ashes separated by an electrostatic...
