Özet

In this study, co-combustion of woodchips and Bursa-Orhaneli lignite was carried out in a circulating fluidized bed combustor, 6 m long and 108 mm inside diameter. Co-combustion of lignite and woodchips was performed in order to investigate the effect of secondary air ratio (SAR) on the flue gas emissions. The woodchips content of the fuel mixture was 30% and 50% by wt. Secondary air (SA) was supplied to the combustor from five different locations along the combustor and at several SARs. During the combustion experiments, CO2, CO, O-2, NO, and SO2 emissions in the flue gas were continuously measured and recorded by ABB-AO 2000 flue gas analyzer.
