  • 摘要: 基于小型流化床焚烧实验平台，通过含油污泥与煤混合燃烧，分析气体污染物排放浓度以及灰渣特性。含油污泥与煤混烧后NOx、SO2的排放浓度均低于危险废物焚烧排放标准。根据灰渣中组分分析，煤中碱金属化合物能抑制SO2的排放。渣样的浸出毒性均在标准范围内，灰样的浸出毒性高于渣样，主要因为飞灰中更容易富集挥发和易溶形态的重金属。基于小试实验的结果，油泥在小型流化床上的燃烧不充分导致了CO排放浓度较高，且灰的灼减率较高，因此，在后续中试以及示范工程中，应保证油泥的充分燃烧，为灰渣的综合利用提供理论基础。
    Abstract: The co-combustion experiment of oily sludge and coal was carried out on a lab-scale fluidized bed incineration test platform to investigate the emission of gas pollutants and the characteristics of ash and residue. Results showed that the emission of NOx and SO2 was lower than the emission standards for hazardous waste incineration, which was due to the inhibition of SO2 emission by the alkali metal compounds in coal. The leaching toxicity of the residue was within the standard range. However, the leaching toxicity of the ash was higher than that of residue, due to the fact that the heavy metals in volatile and soluble forms were more likely to be concentrated in ash. The CO emission far exceeded the standard value and the ignition loss of ash was high, which was possibly attributed to the insufficient combustion of oily sludge in the lab-scale fluidized bed. Therefore, it is important to achieve the sufficient incineration of oily sludge in the subsequent pilot and demonstration projects. Results can provide theoretical support for the comprehensive utilization of ash and residue.
