Detecting Flame Instability in Refinery Burners
Reduce the risk of burner flame-out and prevent unplanned heater shutdowns
Increase Safety with Process Intelligence Diagnostic Capabilities
Burner Flame out can be caused by a number of different sources: damage to fuel tips, blockage of air or fuel supplies, faulty control valves or systems. If Flame-out does occur, it can cause unsafe hazardous environments, unplanned unit shutdowns, and reduce throughput. It's important to maintain a stable combustion for safe operation of fired heaters.
The Rosemount 3051S with Advanced Diagnostics has the capability of high frequency process monitoring. By sampling pressure 22 times per second, this Process Intelligence diagnostic can alert control systems to abnormal process conditions. Flame instability is one such condition that can be detected using this diagnostic feature. If detected early enough, root causes of flame instability can be corrected before flame-out occurs.
