Abstract: A refractory tile system (60) includes a barrier layer coating (61) applied to the wall (16) of a boiler. Refractory tiles (66) are then fastened to the tu be wall (16) utilizing a floating attachment mechanism (68) to provide a relatively high degree of freedom of movement relative to the tube wall to accommodate micro-scale bowing of the tile generated by the relatively large temperature gradient and mean temperature typically experienced by such tile s. Each tile (66) is also isolated from adjacent tiles by providing a predetermined gap (70) therebetween of sufficient size to effectively preven t macro-scale bowing. Moreover, a compressible fibrous mortar is disposed in t he gap between each adjacent tile to prevent contaminants from passing therethrough.

Abstract: A hydraulic system is provided for securing a cylinder liner to a pump module of a reciprocating pump, such as a mud pump. The hydraulic system includes a body attached to the pump module, a ram in sliding contact with the body and having a mating surface, preferably a radial shoulder, contacting the liner. Upon pressurization of fluid in a chamber defined by the body, the ram, and a pair of seals therebetween, the ram slides between a first position and a second position. The ram secures the liner to the module when in the first position and is removable in the second position. The system further includes a locking ring that engages the body, may be hand rotated upon pressurization, and mechanically holds the ram in the first position in the absence of hydraulic pressure. The hydraulic system :is adapted to apply a precise axial securing force and to aid alignment of the liner.
