| Cardox port safety device |
Description
Cardox tubes are used extensively in cement plants to clear process blockages by the controlled rapid discharge of high pressure CO2 stored in the tube. Cardox ports are used to allow access to inspect and clear build up of material within the process. A port cap is removed to inspect internally for build up and, if required, the tube is then inserted to clear the blockage. However, on some occasions due to a blockage, hot material at 900°C+ immediately flows out of the port when the cap is removed. This exposes the operator to high risk and makes it very difficult to replace the cap to stop the flow of material.
CEMEX UK’s mechanical team at the Rugby Plant developed a cover which can be fitted over the Cardox port, equipped with a closable spade. If material starts to flow when the cap is removed, the operator can slide the cover across stopping the flow without the need to replace the cap. A safe system of work for the inspection of Cardox ports is now in place with all operatives trained.
