水煤浆加压气化原料用煤的选择及更换

摘要

渭河化肥厂原采用的黄陵煤，由于煤质灰分含量及灰熔点偏高，影响了德士古气化炉长周期稳定运行。经广泛调研分析之后，将原料煤更换为华亭煤，基本满足了气化炉长周期稳定运行的要求。本文对原料煤更换的原因进行了分析论证，对试烧及结果进行了总结，提出了今后原料煤选择的一些方法。%The feed coal firstly used in Weihe Chemical Fertilizer Plant was from Huangling,the gasifier could not running in a long period and stable because of the high ash content and higher ash fusion temperature point.After careful researching and analyzing,we changed coal from Huangling to Huating,therefore meet the demand of stable and long time running.The reason of replacing the coal is analyzed,the test running and the results are summarized in this paper.In the end,the methods to select the coal used in gasification process are put forward.
