Application Scenarios
Make combustion cleaner, more efficient and safer
COEN Fire Detection Renovation Case
Background of the project
◆ Boiler information: 2X330 MW W flame boiler
◆ Manufacturer: FOSTER WHEELER, USA
◆ Number of coal burners: 24
◆ Number of oil burners: 24
There is a problem
◆ The detection signal of the original equipment is weak, the signal is unstable, the anti-interference ability is poor, and the failure rate is high;
◆ The original equipment cannot detect the flame when the load is low, and the product has poor adjustability and adaptability, and cannot adapt to complex combustion conditions;
◆ Spare parts Expensive and long delivery time;
Solution
◆ Replace the original COEN's iScan fire detector with Safe-Fire's W-FLAME series fire detector, which has stable performance and strong anti-interference ability;
◆ W-FLAME fire detector can adjust the bandwidth, frequency, gain and other parameters in real time. Accurately detect the burning condition of the target flame;
◆ Safe-Fire's W-FLAME series fire inspection has a short delivery cycle and high cost performance.

Result
◆ The fire detection signal detection is stable, which improves the safety of the fire detection system;
◆ The fire detection protection is put into normal operation, improving the safety of the boiler;
◆ The fire detection probe does not need to be debugged, reducing the maintenance workload and improving the user experience.
