Gasification system flow damping

A gasification system component comprising:

• a pool of cooling fluid;
• a vessel configured to retain the pool of a cooling fluid;
• a dip tube disposed in the vessel to direct another fluid towards the pool;
• a draft tube encircling the dip tube to form an inner chamber between the dip tube and the draft tube and an outer chamber between the draft tube and the vessel walls;
• and
• a flow damping mechanism comprising:
• a first annular ring disposed contiguous to the vessel;
• and
• a second annular ring disposed contiguous to the draft tube, wherein the first and second annular rings are configured to form a tortuous flow path for the cooling fluid through the outer chamber to dampen flow of the cooling fluid, or the another fluid, or both within the gasification system component, and wherein a level of the cooling fluid in the pool is high enough that the first and second annular rings extend below the surface of the pool.
