Abstract A 600 MW coal-fired boiler with a four-corner tangential combustion mode is considered here to study the combustion features and pollutant emissions at different loads for large-percentages of blending dried sludges. The influence of the over-fired air (OFA) coefficient is examined and the impact of the blending ratio on the boiler operation is explored. The results show that for low blending ratios, a slight increase in the blending ratio can improve the combustion of bituminite, whereas a further increase leads to the deterioration of the combustion of blended fuels and thus reduces the boiler efficiency.
