The Burner Quarl's are made up of individual tiles, each of which is pre-pressed and fired in a kiln, resulting in a tile that has a ceramic bond throughout the thickness of the tile. In order to achieve the desired bond, the atmosphere, temperature and moisture level in the kiln is carefully monitored and controlled. Quarlcor's kiln's are dedicated solely to the firing of refractory materials which results in the long expectancy of the tiles.

Failure of traditional mouldable and castable material occurs at various stages of the Burner Quarl life, but generally these materials are not able to last between major G.O's without major repairs or failure. Shrinkage and cracking of these traditional materials typically occurs during the first 48hours after start-up because of trapped moisture and cavities.
The only way to achieve a proper ceramic bond is to subject castable materials to a proper thermal cycle at elevated temperatures on site and in the boiler. This is impossible to achieve due to the size and nature of steam boilers.

• To combat the severe erosion experience in the flue gas ducting with intention of reducing the regular maintenance that has to be performed on the unlined steel in these highly erosive areas.
• Quarlcor (PTY) Ltd's ability to manufacture tiles with the desired 10mm thickness required.
• The exceptional wear and thermal resistance of Silicon Carbide
• Relatively low density that is characterised by the Silicon Carbide compared to conventional liners.
• The tile size choice and packing allows for relatively easy Silicon Carbide tile lining material loading through the restricted manhole openings.
