Anhui XX Thermal Power Plant, with an installed capacity of 2 * 660MW,The boiler is a four corner tangential circular combustion, and a single unit is equipped with 24 coal powder burners,12 ignition oil burners,The flame detection system is a FORNEY brand UNIFLAME integrated 95IR flame detector and related accessories, and the detection method is fiber optic detection.

After five years of operation, the flame detection system has encountered some problems that seriously affect the safe operation of the unit:

1. The front end of the flame detection system conduit attachment has severe dust accumulation, resulting in a large workload of flame detection maintenance.
2. The fiber optic accessories of the flame detection system are severely damaged.
3. Some flame detectors have unstable signal outputs. Or there may be signal saturation overflow and unstable output.
4. The parameters of the flame detector have a gain setting range of 1-31, and there is no room for adjustment in case of poor combustion conditions.
XNCT company provides targeted renovation measures based on the characteristics of the site,Effectively solved on-site problems.

1. Improvements have been made to the conduit accessories, using patented double-layer cooling air technology to effectively solve problems such as dust accumulation and fiber optic damage.
2. Improved the UNIFLAME integrated flame detector, using the AP7000 system flame detector, which is more powerful and suitable for applications under different working conditions, and achieves seamless docking with the UNIFLAME cable interface.
