Clinker Cooler Wear Inserts

Reliable Oxytron™ Silicon Carbide wear resistant inserts are designed to be inserted in tubular air preheater tubes; both in the inlet and outlet ends. Engineered with thin walls, flanges and precise tolerances, they serve to protect the weld integrity and first several inches while absorbing the brunt of abrasion from the ash as it makes its turn into the tubes. Blasch silicon carbide inserts are custom designed, maximizing plant efficiencies and capital equipment life while reducing maintenance downtime. Available in several abrasion resistant silicon carbide materials, including Oxytron™ that are far superior to metallic inserts or coatings, Blasch Oxytron inserts can often seal up existing holes allowing maintenance engineers to keep the plant on line.

Boiler efficiency improvements are very important, particularly in today’s highly competitive environment. That is why erosion of the air heater tubes and the tubesheet are such serious problems.

Erosion can penetrate the tube to tubesheet weld allowing dirty, hot gas into the clean air stream creating erosion problems in some very hard to access areas. When this occurs, it is usually necessary to cut out tubes and replace them. This is an expensive and time-consuming process. In cases where the damage is not obvious until the unit is opened, this can extend the outage and cause potential disruptions in service. Leakage at the tube to tubesheet weld or otherwise into the tubes is also undesirable in that it increases fan power requirements in direct proportion to the size of the leaks. This impairs the efficiency of the air heater as well. Ceramic is well known, and routinely used, to prevent erosion in areas of high wear.

Product Information Sheets


All-Round Ceramic Protection

Erosion can significantly reduce the operational life of cement production equipment and speed up the replacement of key components. The use of abrasion-resistant precast ceramic parts can be a sound alternative to expensive metallic shapes or cast refractory.

Extended Heat Exchanger Life

Blasch Precision Ceramics has designed an alternative to Ni-Hard cast iron inserts in tube sheets designed to protect the tube end and extend the life of clinker cooler heat exchangers, situated downstream of the cooler and ahead of the kiln baghouse filter, yielding a number of savings.
