How to install high-temperature monitoring devices on coke ovens in an extremely hot outdoor environment?
Process
Transforming coal into coke – a key ingredient used to manufacture steel.
Raw coal is exposed to high temperatures in a group of industrial coke ovens(a battery) with averages up to 1200ºC.
Blazing coke is cooled with water and then conveyed for use in iron smelting process.
Other volatile by-products like tar and gas are collected, separated and purified to be used in other industries.
Objective
Monitor temperatures in the gas collecting pipes connected to the top of the coke ovens in extreme ambient temperatures with minimal infrastructure upgrades.
Solution
Installation of Tekon Thermocouples suitable for use in high temperature environments hard wired back to a cabinet installed in a “cleaner” and safer area close to the ovens. From there an integrated solution of Universal temperature transmitters and Wireless transmitters significantly reduced the deployment time and cost to collect this data. The wireless gateway collects the data from the transmitters and directly connects it to the PLC, SCADA or Monitoring Dashboards.
Technical Details
Thermocouples and cables matches to the clients requirements.
Fully-assembled cabinet with a mixed set of Tekon wired and wireless transmitters:
4x TDU301-I transmitters
(directly connected to thermocouples)
1x PLUS TWP-4AI wireless transmitter
(collect 4..20mA signals from TDU301-I transmitters)
20x cable glands for thermocouples
(directly from installed probes)
Conclusion
Fast Deployment: After installation of the thermocouple probes, this client was able to quickly and easily deploy the in house pre assembled transmitter enclosure.
Low Cost Installation: Reduced commissioning hours and materials cost where possible due to pre assembled enclosures and wireless transmission removing the
requirement for long cables.
Future Proof System: This deployment takes a step into the digital direction. The system is future proofed and has the possibility of expansion using the single gateway for up to 55 transmitters and 220 temperature sensors.
