Abstract

In this study, co-combustion of Bursa-Orhaneli lignite and woodchips mixtures containing 10%, 30% and 50% by wt. of woodchips was studied in a circulating fluidized bed combustor in order to investigate the effect of excess air ratio (k) on the flue gas emissions. The combustor has an inside diameter of 108 mm and a height of 6 m. The temperature of the combustor is kept at 850 degrees C during the combustion tests. During the combustion tests, CO, O-2, NO, and SO2 emissions in the flue gas was continuously measured and recorded by ABB-AO 2000 flue gas analyzer.
