摘要:

为了降低生产成本,确保多喷嘴对置式水煤浆气化装置长周期稳定运行,对新疆煤和内蒙古煤进行了试生产运行,在相同工况下重点考察了原料煤单耗、制得的水煤浆浓度与黏度、有效气成分、灰水中氯离子含量、煤浆添加剂消耗量等指标。试生产运行结果表明,内蒙古煤各项指标优于新疆煤,有利于气化装置长周期稳定运行。

Abstract:

In order to reduce the production cost, ensure the long term stable operation of the multi-nozzle opposed coal-water slurry gasifier, trial production operation of the coal from Xinjiang and Inner Mongolia were carried out. The unit consumption of feed coal, the concentration and viscosity of the coal-water slurry, contents of effective gas, chloride ion concentration of the ash water, and the consumption of coal-water slurry additive were emphatically investigated under the same operating condition. The results showed that feed coal from Inner Mongolia is better than that of Xinjiang in various aspects, which is beneficial to the long term stable operation of the gasification unit.
