Coal gasification is a kind of gasification technology which takes water and oxygen or carbon dioxide as gasification agent to produce gas. Now the common gasification device system is GE gasification device. The operation of GE coal water slurry gasifier in the device system is periodic, and the corresponding hidden trouble investigation is periodic, too. The system mainly includes coal grinding system, gasification system and slag water system.GE gasification technology has strong adaptability of raw materials, and effective components in synthetic products are higher. The utilization rate of heat in the furnace is high, but the requirement for coal quality is high, it usually requires coal with ash melting point and high activity, and the life of burner in the process is short. So it is of great significance to carry out periodic hidden trouble investigation for GE gasification plant system.%煤气化是以水和氧气或二氧化碳为气化剂发生反应而生成气的一种气化技术。目前常用的气化装置系统多为 GE 气化装置。该装置系统中的 GE 水煤浆气化炉运行反应具有周期性，对其进行相应的隐患排查也应具有周期性。其装置系统主要包括磨煤系统、气化系统和渣水系统三部分。GE 气化技术具有较强的原料适应性，合成产品中的有效成分较高，对炉内热量的利用率较高，但其对煤质的要求高，通常是灰熔点地且活性高的煤，并且工艺中烧嘴的寿命较短，因此，对 GE 气化装置系统进行定期隐患排查具有重要意义。
