SYSTEM FOR PROTECTING GASIFIER QUENCH RING

摘要

A system includes a gasifier (10), which includes a reaction chamber (12) configured to convert a feedstock (4) into a synthetic gas, a quench chamber (14) configured to cool the synthetic gas, a quench ring (22) configured to provide a water flow to the quench chamber (14), and a quench ring protection system (11) configured to protect the quench ring (22) from the synthetic gas or a molten slag. The quench ring protection system (11) includes a protective barrier (16) disposed within an inner circumferential surface (86) of the quench ring (22). The protective barrier (16) substantially overlaps the inner circumferential surface (86) in an axial direction along an axis (88) of the quench ring (22).
