| 摘 要： | 提出了一种新型的含油污泥焚烧近零排放处理方式，即利用富氧燃烧技术焚烧含油污泥，油泥无需干化，并可以回收烟气中的CO2直接用于油田驱油，可以实现CO2的近零排放。以日焚烧200 t含油污泥为研究对象，构建了鼓泡床富氧燃烧含油污泥锅炉原则性热力系统，并分别从炉膛内密相区埋管、稀相区受热面和尾部对流受热面等方面进行了概念设计，根据鼓泡床锅炉的设计原则并结合富氧燃烧技术特点，设计了一台富氧燃烧含油污泥鼓泡床锅炉。详细介绍了鼓泡床焚烧锅炉的设计参数、结构布置，结果表明：鼓泡床富氧焚烧含油污泥系统的锅炉效率可达92.59%，富氧燃烧工况下炉膛内的换热量远远大于对流换热量。

| Abstract: | A new type of oily sludge incineration with flue-gas near-zero emissions was put forward. This method uses oxygen-enriched combustion technology to incinerate oily sludge where drying is not required, and CO2 can be recycled to be used in oil field flooding, achieving near-zero CO2 emissions. In this study, oil sludge (200 t·d-1) was incinerated via oxygen-enriched combustion in a fluidized bed, serving as fuel for a boiler. The system was constructed from a conceptual design considering the heating surfaces of dense segments, dilute segments, and the tail section of the boiler. Considering the characteristics of oxygen-enriched combustion and the design principles of a fluidized bed boiler, an oxygen-enriched fluidized bed boiler was designed. The design parameters and structural layout of this fluidized bed boiler are shown in detail. Results indicated that the boiler efficiency of oxygen-enriched combustion of oily sludge can reach 92.59%. Additionally, heat transfer in the furnace was much higher with fluidized bed oxygen enriched combustion. |
