摘要
介绍煤气化技术概况。论述近期煤气化技术发展的六大特点,即从装备国产化走向工艺技术国产化,单元技术进步引导全生产线"安稳长满"运行,单炉规模大型化,气化炉内操作压力提高,原料向褐煤发展,气化后两种流程可以组合。提出选用煤气化技术的七项原则:以煤定炉,优先考虑气流床,气化炉规模适中,力求技术成熟、投资低、环保,超大型煤化工装置需要备炉。煤气化技术的选择决定了全装置运行状况的好坏。
Generally describe status of coal gasification technology. And discuss six characteristics of recent coal gasification technology development, which including developing process technology localization from equipment localization, unit technological progress guiding whole production line operation in the condition of safety, stability, long period and full load, single gasifier being developed towards large scale one, gasifier operating pressure being increased, lignite tending to be used as the raw coal, both processes would be combined after gasification process. Propose seven principles of
