The refractory protected, replaceable insert for a gasifier includes a replaceable floor edge insert that is formed with a predetermined mating profile that is complementary to a finished mating profile of the gasifier floor. The geometry of the mating profiles of the replaceable floor edge insert and the gasifier floor permit removable engagement between the floor edge insert and the mating profile of the gasifier floor. The replaceable floor edge insert is protected by a ring-like arrangement of hanging refractory bricks that each include an appendage. Each brick appendage covers a portion of the inner radial edge of the replaceable floor edge insert and also covers an upper surface portion of an underlying quench ring, thus prolonging the life of the floor and the quench ring. A refractory ceramic fiber paper can be provided between the hanging brick and the floor edge and quench ring. Also, a refractory ceramic fiber rope can be provided at the inner peripheral edge of the replaceable floor edge insert upon the upper surface of the quench ring, and overlaid by the appendage.

The self-anchoring expansion gap assembly for refractory lined vessels such as a gasifier includes a substantially annular insulating blanket structure formed of compressible refractory material. A coil of rope formed of relatively incompressible refractory material is positioned proximate an outer periphery of the insulating blanket structure. The expansion gap assembly is placed in an expansion gap of a gasifier, for example, such that the coil of rope aligns with an annular channel formed in the refractory lining of the gasifier at the expansion gap. Compression of the expansion gap assembly locks the coil of rope in the annular channel of the expansion gap thereby resisting vacuum pullout. The coil of rope can be formed as a single coil or a plurality of substantially concentric coils preferably from a single length of refractory rope.
