【摘要】 针对抚顺式干馏炉加热效率偏低的问题，提出富氧热解工艺优化方案。通过数值模拟手段，深入研究O₂浓度对发生段温度、气体组分以及能量特性的影响。研究结果表明：随O₂浓度升高，发生段的燃烧温度随之上升；在气体组分方面，CO₂占比增加、CO占比降低；发生瓦斯的质量流量呈单调递减趋势，比显焓整体呈递增态势（仅在O₂浓度达到36%时出现短暂下降）；总显焓呈波动性增长。本研究为油页岩富氧热解提供了理论依据，通过灵活调控O₂浓度可降低干馏段对额外热源的需求，推动自热式干馏工艺的实现，为抚顺式干馏炉的高效运行开拓新的路径。更多还原

【Abstract】 Aiming at the problem of low heating effici ency of the Fushun-style retort furnace, this study proposes an optimization scheme for the oxygen-enriched pyrolysis process. Through numerical simulation methods, it investigates the influence of O₂ concentration on the temperature, gas composition and energy characteristics of the generation section in depth. The research results show that, as the O₂ concentration gradually increases, the combustion temperature of the generation section rises accordingly.For gas composition, the proportion of CO₂ increases while the proportion of CO decreases; the mass flow rate of the generated gas shows a monotonically decreasing trend, and the specific sensible enthalpy generally shows an increasing trend, with only a brief decrease when the O₂ concentration reaches 36%; at the same time, the total sensible enthalpy shows a fluctuating growth. This achievement provides a theoretical basis for the oxygen-enriched pyrolysis of oil shale. It is expected that by flexibly adjusting the O₂ concentration, the demand for additional heat sources in the retorting section can be reduced, and the realization of the self-heating retorting process can be promoted, opening up a new path for the efficient operation of the Fushun-style retort furnace.更多还原
