CFBC에서 유연탄과 축산슬러지의 혼합연소 특성 연구 = A Study on Combustion Characteristics of Mixed Firing of Coal and Livestock Waster in CFBC

다국어 초록 (Multilingual Abstract)

Bio-SRF (Bio-Solid Refuse Fuel) based on livestock waste has a low heating value and high moisture content. Theconcentration of toxic gas, such as SOx, NOx, and HCl, in the flue gas is changed according to the composition of fuel,which has been reported. Therefore, the study of fuel combustion characteristics is necessary. Additionally, the study offuel firing characteristics is necessary. In this study, we investigated the combustion characteristics of the mixed firingof coal and Bio-SRF made from livestock waste in a circulating fluidized bed combustor (CFBC). The Bio-SRF oflivestock waste was mixed with different ratios of coal based on the heating values when the coal was completelycombusted in CFBC. In the results of the experiment, the combustor efficiencies of the calculated unburned carbonconcentration in the fly ash were 98.87%, 99.04%, 99.64%, and 99.71% when the multi-firing ratio of livestock sludgeincreased from 100/0 to 70/30. In addition, the boiler efficiencies were 86.23%, 86.30, 87.24, and 87.27%. Through theexperimental results, we identified that the mixed combustion of livestock sludge is not affected by boiler efficiency. Wehave systematically investigated and discussed the temperature changes of an internal combustor, compositions of fluegases, solid ash characteristics, and the combustion and boiler efficiency during the mixed firing of coal and Bio-SRF.
