Abstract Three coordinated papers are presented concerning entrained flow gasification of a liquid fuel under atmospheric conditions. The work is based on a detailed mapping of process parameters inside the entrained flow gasifier and at the gasifier outlet. In this paper the experimental setup and the experimental data are reported. Mono ethylene glycol (MEG) is used as a well-defined surrogate fuel for biogenic oils. The overall performance of the reactor is evaluated by measuring the gas-phase composition at the reactor outlet; radial profiles of gas-phase composition (CO 2 , CO, H 2 , CH 4 , hydrocarbons) and temperature at 300 and 680 mm distances from the burner are measured to describe the mixing and reaction pattern in the gasifier. Global and local species balances are used to derive data that are not accessible by measurement. Characteristic parameters, i.e. stoichiometry, carbon conversion and water gas shift temperature, are derived to assess consistency of the measured data. Droplet size distribution and droplet velocity at the burner nozzle are reported based on atomization test rig experiments and direct measurements in the burner near field under gasification conditions. The experiments show a free jet with a strong outer recirculation zone as core gasification pattern. The measured species concentrations and temperatures provide an insight into both the mixing and the reactions in the burner near field. The water gas shift equilibrium is reached for a temperature of 1495 K upstream of the gasifier outlet. Hydrocarbons are not completely converted due to the low temperatures near the gasifier outlet. The research work has been conducted within the research cooperation of the Helmholtz Virtual Institute HVIGasTech.

气流气化第 1 部分：在常压实验装置中乙二醇的气化

摘要 提出了三篇关于大气条件下液体燃料夹带流气化的协调论文。该工作基于对夹带流气化器内部和气化器出口处的工艺参数的详细映射。在本文中，报告了实验装置和实验数据。单乙二醇 (MEG) 被用作明确定义的生物油替代燃料。通过测量反应器出口处的气相组成来评估反应器的整体性能；测量距燃烧器 300 和 680 毫米处的气相成分（CO 2 、CO、H 2 、CH 4 、碳氢化合物）和温度的径向分布，以描述气化器中的混合和反应模式。全球和本地物种平衡用于得出无法通过测量获得的数据。导出特征参数，即化学计量、碳转化率和水煤气变换温度，以评估测量数据的一致性。燃烧器喷嘴处的液滴尺寸分布和液滴速度是根据雾化试验台实验和气化条件下燃烧器近场中的直接测量报告的。实验显示自由射流以强外部再循环区作为核心气化模式。测量的物质浓度和温度提供了对燃烧器近场中的混合和反应的深入了解。在气化器出口上游 1495 K 的温度下达到水煤气变换平衡。由于气化器出口附近的低温，烃没有完全转化。
