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.
In a gasifier having a throat section and a metal floor with a throat opening at the throat section, the throat opening in the metal floor being defined by an inner peripheral edge of the metal gasifier floor, and the metal gasifier floor has an overlying refractory material, the improvement comprising a hanging refractory brick for the overlying refractory material of the gasifier floor at the inner peripheral edge of the metal floor, the hanging refractory brick having opposite end portions, opposite side portions, a top portion and a bottom portion, the bottom portion including an appendage, the appendage having a vertical extent that extends a predetermined amount below one of the opposite end portions, the vertical extent of the appendage being selected to overhang a portion of the inner peripheral edge of the metal gasifier floor.
In a gasifier having a throat section and a metal floor with a throat opening at the throat section, the throat opening in the metal floor being defined by an inner peripheral edge portion of the metal floor, and the metal gasifier floor having an overlying refractory material, the improvement comprising a replaceable metallic floor edge insert for positioning at the inner peripheral edge portion of the metal gasifier floor when the inner peripheral edge portion is finished to form a first predetermined mating profile in cross-section, the replaceable floor edge insert having a radially inner edge portion that becomes a leading edge or free edge of the metal floor, and a radially outer edge portion, the radially outer edge portion having a second predetermined mating profile in cross-section, complementary to the first predetermined mating profile of the finished inner peripheral edge portion to permit engagement of the replaceable metallic floor edge insert with the finished inner peripheral edge portion of the metal gasifier floor such that the replaceable metallic floor edge insert forms a removable extension of the metal gasifier floor.
A method of facilitating repair of a metal gasifier floor at a throat opening in the gasifier floor including
