What are the reasons for the deformation of downcomers in coal gasification?

Reply #22016-12-13

Insufficient or uneven cooling water flow, clogged slag outlets, and deterioration in coal quality leading to poor fluidity of coal ash, among other issues.

Is there anyone who can provide a detailed and specific analysis?

You can look up the article from Northwest Coal Chemical Engineering, Issue 2, 2004: Analysis of the causes of damage to the downcomer in the Texaco water-coal slurry gasifier

Changes in coal quality, slag hole blockage, uneven distribution of quenching water, low flow rate, etc

Mainly, it is the insufficient or uneven distribution of quench water that causes overheating in the downcomer.
