ABSTRACT:
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.
