Key to Success: Preventative Maintenance
Safety is always top priority. Have you considered having Onex perform preventative maintenance on your furnace to keep it running as safely and efficiently as possible?
What is Preventative Maintenance?
With a plan tailored to your equipment and operational requirements, preventative maintenance can include checking safety interlocks, setting burner gas and air for optimal efficiency and assisting in temperature uniformity. Other related tasks include replacing combustion components such as flame rods or valves, cleaning the furnace, and repairing weak points in the refractory of the furnace. A proactive approach to maintaining equipment is highly beneficial to maximizing the lifespan and significantly decreasing unexpected downtime of the equipment.
Our technicians will provide you with a full report, giving solutions for any issues that may have been found.
Successful Combustion Service
Recently Onex was called in to perform work on a 32 burner walking beam system that hadn’t been operating correctly. This particular unit required the manual intervention of a 24/7 operator who would monitor thermocouple temperatures and make adjustments to temperature set points on the fly. The system was on a roller coaster of temperature swings, and it became a “normal” operation.
With the help of our skilled Onex combustion team, we were able to start at the beginning and take measurements of the air and gas values for each burner. This furnace was designed with a lead-lag cross-limiting combustion system, meaning the air and gas had to be tuned in sequence. After troubleshooting, Onex was able to optimize the performance of the furnace through burner tuning and PID loop control modifications. The furnace is operating better than ever, and the lead operator has not had to make any manual adjustments since the work was completed in late Q2, 2021.
Benefits of Scheduled Maintenance
With proper scheduled maintenance, you can expect the following:
Equipment optimization and a decrease in unplanned downtime
Lower chance of unplanned problems during outages
Decreased number of quality problems in products
Decreased repair costs due to inspections or service
Increase in the expected life of equipment
Increased fuel efficiency due to proper functionality of equipment
Onex combustion technicians ensure furnace safety interlocks are functioning per the OEM design and meet NFPA 86 requirements. If any issues are detected, our team will work alongside you to find the best solution, just as we did with the 32 burner walking beam furnace.
