以一个工业对置式多燃烧器气化装置为背景，根据系统的工业数据，对气化炉内的耐火材料进行了全面的分析，包括宏观结构和分区侵蚀特性的研究。并将计算结果与实验室气化平台和数值模拟结果进行了比较。在工业OMB气化炉中观察到耐火材料的五个严重侵蚀区域：两个在撞击上流区，一个在燃烧器平面，一个在撞击下流区，一个在锥形区。拱顶区和推流区耐火材料的侵蚀较轻。下侧壁上的剥落是不均匀的;因此，两个相邻燃烧器之间的区域下方的砖在纵向方向上被侵蚀得更多。研究结果可为新型耐火材料结构的开发和超大型气化炉的优化设计提供参考。(C)2019爱思唯尔有限公司版权所有。
Based on an industrial opposed multi-burner (OMB) gasification plant, a complete review of spent refractory materials inside a gasifier, including a study of the macrostructure and partitioned erosion characteristics, is reported based on systemic industrial data. The results are compared with those from a bench-scale gasification platform as well as numerical simulation. Five heavily eroded regions of the refractory were observed in the industrial OMB gasifier: two in the impinging up-flow zone, one in the burner plane, one in the impinging down-flow zone, and one in the cone zone. The erosion of the refractory material in the dome zone and the plug-flow zone is mild. The spalling on the lower side wall is uneven; therefore, the bricks below the region between two adjacent burners are more eroded in the longitudinal direction. Herein, the results can be used for the development of new refractory structure and the optimization of ultra-large-scale gasifiers. (C) 2019 Elsevier Ltd. All rights reserved.
