The impact of periodic feeding mode on the concentrations of carbon monoxide (CO) and nitrogen oxides (NO, NOx) in the flue gas downstream the boiler was analyzed during firing of a mixture of sunflower husk and wood pellets in an overfeed furnace. The mixtures containing 100, 70 and 50 wt. %, of sunflower husk pellets were supplied to the boiler in two feeding modes: 1 s of operation 4 s of stand-by and 1s of operation 6 s of stand-by. Correlation between pollutant concentrations and the temperature in the combustion chamber was evaluated. The following concentrations of CO for various feeding modes and sunflower husk pellet proportions have been obtained: 1:6,100% - 6150 mg/m3,1:6,70% - 3360 mg/m3, 1:6, 50% - 2600 mg/m3, 1:4,100% - 4580 mg/m3,1:4, 70% - 2570 mg/m3, 1:4,50% - 870 mg/m3 for 10% O2 content in the flue gas. The study indicates the advisability of reducing the stand-by period in the pellet feeding system.
