Abstract
Abstract A module is provided which comprises a casing having an inlet and outlet face and a transition refractory material anchored in the casing which surrounds and contains a monolith or monoliths having longitudinal and transverse axes, which monolith or monoliths provide an unobstructed flow path between the inlet and outlet faces of the casing, the lowest compressive strength of the monolith measured perpendicular to a longitudinal axis being greater than the compressive strength of the transition refractory material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
130 words
A MODULE WHICH COMPRISES A CASING HAVING AN INLET AND AN OUTLET FACE AND AN INTERIOR AND EXTERIOR SURFACE, SAID INTERIOR SURFACE OF THE CASING HAVING SOME PHYSICAL OR MECHNICAL MEANS TO WHICH A RIGID TRANSITION REFRACTORY CEMENT CAN BE ANCHORED, A MONOLITH WITHIN SAID CASING AND HAVING AT LEAST ONE LONGITUDINAL AND TRANSVERSE AXIS, WHICH MONOLITH ALLOWS SUBSTANTIALLY UNOBSTRUCTED FLOW BETWEEN THE INLET AND OUTLET FACES OF THE CASING, A RIGID TRANSITION REFRACTORY CEMENT ANCHORED TO THE INTERIOR SURFACE OF THE CASING AND TO THE OUTER PERIPHERY OF THE MONOLITH, THE MATERIALS OF CONSTRUCTION OF SAID MONOLITH AND SAID RIGID TRANSITION REFRACTORY CEMENT BEING SUCH THAT THE LOWEST COMPRESSIVE STRENGTH OF THE MONOLITH MEASURED PERPENDICULAR TO LONGITUDINAL AXIS BEING GREATER THAN THE COMPRESSIVE STRENGTH OF THE TRANSITION REFRACTORY CEMENT.
Claim 2
Dependent Claim
