| 2 | Compositional and structural study of ash deposits spatially distributed in superheaters of a large biomass-fired CFB boiler显示文摘Recognizing the nature and formation progress of the ash deposits is essential to resolve the deposition problem hindering the wide application of large-scale biomass-fired boilers.Therefore,the ash deposits in the superheaters of a 220 t/h biomass-fired CFB boiler were studied,including the platen(PS),the high-temperature(HTS),the upper and the lower low-temperature superheaters(LTS).The results showed that the deposits in the PSs and HTSs were thin(several millimeters)and compact,consisting of a yellow outer layer and snow-white inner layer near the tube surface.The deposits in the upper LTS appeared to be toughly sintered ceramic,while those in the lower LTS were composed of dispersive coarse ash particles with an unsintered surface.Detailed characterization of the cross-section and the initial layers in the deposits revealed that the dominating compositions in both the PSs and the HTSs were Cl and K(approximately 70%)in the form of KCl.Interestingly,the cross-section of the deposition in the upper LTS exhibited a unique lamellar structure with a major composition of Ca and S.The contents of Ca and Si increased from approximately 10%to approximately 60%in the deposits from the high temperature surfaces to the low temperature ones.It was concluded that the vaporized mineral matter such as KCl played the most important role in the deposition progress in the PS and the HTS.In addition,although the condensation of KCl in the LTSs also happened,the deposition of ash particles played a more important role. | Yishu XU Xiaowei LIU Jiuxin QI Tianpeng ZHANG Minghou XU Fangfang FEI Dingqing LI | 2021 | Frontiers in Energy2021，15，2： | 3 |

| 19 | Recent studies on railway-track substructure at TTCI显示文摘Railway-track substructure is the foundation of the railway-track infrastructure and consists of four major components:ballast,sub-ballast,subgrade and drainage.Safety and performance of the track infrastructure,to a large degree,depends on the performance of the track substructure.Adequate support from the track substructure is the most critical element needed for good track performance.When properly constructed and maintained,the ballasted track is the most cost-effective track structure for railway operations,especially for heavy-haul freight operations.Good track-substructure support is characterized by good drainage and strong resistance of the ballast,sub-ballast and subgrade layers to excessive deformation and failures under repeated dynamic wheel loads.As the track substructure plays such important roles,research concerning track substructure has been broad and extensive around the world,with many universities and research institutes conducting various studies and investigations.This paper provides an overview of the recent research conducted at Transportation Technology Center,Inc.(TTCI),a subsidiary of the Association of American Railroads(AAR),in the following areas:ballast mud pumping and its effects on track performance,remediation of subgrade mud pumping,remediation of ballast pockets,ground-penetrating radar(GPR)for inspecting track substructure,and development of software tools with focus on track-substructure functions and management. | Dingqing Li Stephen Wilk | 2021 | Transportation Safety and Environment2021，3，1： | 0 |
| 20 | 混凝土轨枕轨道使用钢轨防爬器的试验显示文摘由美国运输技术中心(TTCI)与美国太平洋铁路公司(UP)共同进行的运营线路试验结果显示,在混凝土轨枕试验点安装的防爬器,对于减少中和轨温的短期或长期的变化都没有起到增强的作用.同时.当一对绝缘接头夹板出现裂缝时也未能阻止中和轨温的大幅度下降。 | Rafael Jimenez Li Dingqing Ed Kohake 宋文伟(译) | 2010 | 世界轨道交通2010，，9： | 0 |
