| Summary: | 碩士 === 國立高雄科技大學 === 環境與安全衛生工程系 === 107 === The petroleum industry produces a lot of oil sludge during production process and storage, which contains amounts of hydrocarbons, is suitable for recycling and reuse as an available resource. Though the oil sludge contains high heating value, it is difficult to be ignited. In this study, waste mushroom bag with good combustion characteristics is added, and blended in different proportions to evaluate the feasibility of making refuse derived fuel (RDF). The blending ratio (weight ratio, g/g) is 8:2 (O8:M2), 7:3 (O7:M3), 6:4 (O6:M4), 5:5 (O5:M5). The results show that the combustibility(87.43, 87.37, 86.78, 86.75%) and heating value(9,176, 8,452, 7,871, 7,279 cal/g) of RDF decrease while the ratio of mushroom bag has increased. On the other hand, the results of the combustion characteristics analysis increase when the ratio of mushroom bag has increased, the comprehensive combustion characteristics are O5:M5 > O6:M4 > O7:M3 > O8:M2. According to the comprehensive evaluation and analysis results, the best ratio of oil sludge and waste mushroom bag is O6:M4(water 8.78%, ash 4.44%, combustibility 86.78%, heating value 7,871 cal/g), it can not only replace some fossil fuels as an energy source, but also assist in the treatment of agricultural waste, in line with the effective use of renewable resources, and achieves the goal of circular economy.
