8月31日12时,由东北分公司全体将士历经八百多个日夜奋战的大唐多伦3#煤气化装置顺利投煤成功,这是继6月7日3#煤气化装置在大唐煤基烯烃项目3套气化装置中第一个实现中交以来,公司在多伦工程施工中又一次实现的第一。
多伦煤基烯烃煤气化装置体积大、质量大、设备多、高温高压多、投料难度大。来自原料系统的碎煤,经过碎煤仓被热风炉送到煤粉过滤器,然后进入煤粉加压装置,通过高压CO2送到气化烧嘴,此间煤粉、氧气和蒸汽混合物在1500℃高温下,瞬间完成煤的气化反应,生成CO+H2,高温粗煤气在气化炉水冷壁和合成器冷却器内回收热量并产生蒸汽,原料煤种的煤粉成熔融态,含大量CO+H2粗合成气经高温陶瓷过滤器及洗涤后经下游使用。
3#煤气化装置的投煤成功,为大唐多伦煤基烯烃工程全面开车、投料奠定了坚实的基础。
