摘要：The new dust removal technical route using the carbon-granular bed filter, packed of carbon particles with appropriate grade derive from an online-process vibration sieve, to replace the traditional baggy filter had been developed successfully for capturing the micro-carbon dusts produced from pulverization of petroleum coke, and the green close loop of carbon materials is thus completed in the combined pulverizing and classifying system and pulverized carbon dust removal process. The high dust removal efficiency greater than 99%, low outlet dust concentration less than 100mg·m-3, low pressure drop through dust filtration chamber less than 980Pa, simple and easy design, and flexible and stable operation were achieved also with the carbon-granular bed filter in both bench and industrial scale operations.

摘要：通过对不同煤种在热天平中的单颗粒燃烧过程的分析发现:煤种、颗粒大小、氧气浓度对颗粒燃烧完全所需要的时间影响特别显著;而在一般流化床生产运行温度范围内,温度对颗粒燃烧完全所需要时间的影响有限;同一煤种不同颗粒煤焦孔隙率的影响很小。通过对单颗粒热天平燃烧实验,考查不同煤种及颗粒大小等各因素对颗粒燃烧过程的影响,可方便地指导流化床的设计以及生产运行过程中工艺的调整。
