Clearing of Build-Ups in Rotary Kilns

Cardox system is widely recognized as the most efficient and cost-effective method of clearing stubborn build-ups and blockages from rotary kilns.

Cardox blockage clearing systemfor clearing the stubborn ring build up inside the rotary kilns shown here. Since Cardox can be used in high heat applications, there was no need for extended shutdown waiting for the equipment to cool.

The fast and efficient process of deploying the tubes and initiating the gas expansion enabled our field crew to successfully clear the build up at controlled pressures that caused no damage to the refractory lining or weakening of the kiln walls.

The task can be accomplished within an hour with minimal disruption to production. Compared to manual cleaning methods that what would take 5 or more days to complete and cause great interference to the processing line, the cost of deploying Cardox is nominal when weighted against significant downtime and production losses due to cool down time & reheat time after clearing

The reliability, efficiency, and reusability of the Cardox tubes provided the effective alternative to conventional or commercial explosives that would have cause a major disruption to port operations.

Cardox has a variety of different tubes for specific applications. Tubes are filled with liquid carbon dioxide (exactly the same as a fire extinguisher). Carbon dioxide gas is an inert gas that is commonly used in fire extinguishers, so it is safe to use.When energized by the application of a small electrical charge, the chemical heater instantly converts the liquid carbon dioxide to a gas. This conversion expands the CO² volume and builds up pressure inside the tube until it causes the rupture disc at the end of the tube to burst. This releases the CO² – now 600 times the original volume – through a special discharge nozzle to create a powerful heaving force, at pressures up to 40,000 psi (3,000 Bar). This all takes place in milliseconds.
