Blasch VectorWall™ Mixing Checkerwall is a versatile, mechanically stable system consisting of a series of stackable, six-sided blocks incorporating alternating tabs and slots on each side that are designed to ensure the blocks are positively locked together at installation. The VectorWall is offered in a highly creep-resistant mullite bonded composition, designed to resist deformation under load.
Our patented VectorWall increases capacity and lowers the operation and maintenance costs of medium and large diameter high temperature reaction furnaces such as those used in Claus Sulfur Recovery Units (SRUs). It replaces and significantly improves upon traditional, weak, unsupported refractory brick baffle walls or checkerwalls with what is usually a smaller overall number of walls that perform the same function, more efficiently, in a shorter distance.
VectorWall employs Blasch’s patented HexWall™ technology as a stable and reliable foundation for use even in oxygen enriched environments. It is stronger, more precise, and uses far fewer parts than standard 9” brick and refractory mortar baffles or checkerwalls for a faster, more secure installation. Rapid disassembly and reassembly of the Blasch VectorWall can easily be achieved for major maintenance turnarounds. Spanning the entire inside diameter of the burner or furnace, the Blasch VectorWall becomes structurally integral with the furnace wall.
Other mechanical advantages include, but are not limited to:
The benefits of the VectorWall mixing checkerwall lie, not only in its mechanical stability, but also in its infinitely variable mixing configurations. These configurations may be adapted to provide optimal mixing regardless of burner types and locations, and they are simple to erect, reducing the need for expensive, highly skilled labor. In addition, the VectorWall checkerwall can be configured for a variety of new flow regimes including tangential vortex flow.
Other process improvements that your plant can expect to achieve include, but are not limited to:
The vast majority of refractory, by volume, used in the refining and petrochemical sectors is in the form of brick or castable. These allow for the greatest flexibility in installation, but greatly limit the ability to develop innovative component and assembly designs that work to the inherent strengths of refractory materials, which can, in turn, provide significant process improvement. One such example is the use of a checkerwall in reaction furnaces to improve various process parameters.
