초록

Waste oil sludge was generated from waste oil purification process, oil bunker, or the ocean plant. Although it has high calorific values, it should be treated as a designated waste. During the recycling process of construction and demolition wastes or the trimming process of woods, a lot of sawdust is produced. In this study, the feasibility of BOF (biomass and waste oil sludge Fuel) as a source of renewable energy was estimated. To estimate combustion characteristics, a lab scale batch type combustion reactor was used and temperature fluctuation and the flue gas composition were measured for various experimental conditions. The results could be summarized as follows: the maximum CO2 concentration in the flue gas was increased with increasing waste oil sludge content in BOF. SO2 concentration in the flue gas was showed a tendency such as the highest CO2 concentration in the flue gas. With increasing waste oil sludge content in BOF, the combustion time was rather shorter although the increase of the CO2 concentration in the flue gas was delayed. Because the carbon conversion rate showed small difference with increasing the mixing ratio of waste oil sludge in BOF, BOF with the mixing ratio of waste oil sludge of 40% was effective for combustion. With decreasing the air/fuel ratio and the mixing ratio of waste oil sludge in BOF, activation energy and frequency factor were increased. The optimal air/fuel ratio for the combustion of BOF was 1.5.
