An improved quench ring in combination with a reactor vessel having a refractory lined reaction chamber with a bottom outlet and a floor to support the refractory lined reaction chamber, wherein the quench ring is protected by a protective barrier comprising dense refractory brick, dense refractory ramming mix, refractory ceramic fiber, and a metal apron support. The protective barrier is removably attached to a portion of the quench ring hotface and protects the quench ring from the high temperature of the effluent exiting the reaction chamber.
