Application Scenarios
Make combustion cleaner, more efficient and safer
DURAG Fire Detection Renovation Case
Background of the project
◆ Boiler information: 2X315 MW four-corner tangential boiler
◆ Manufacturer: Dongfang Boiler Co., Ltd.
◆ Number of coal burners: 24
◆ Number of oil burners: 12
There is a problem
◆ The detection capability of the original flame detector is weak, the fire detection signal fluctuates greatly, the anti-interference ability is poor, and the failure rate is high;
◆ The original equipment product has poor adjustability and adaptability, and cannot adapt to complex combustion conditions;
◆ The original flame detector The temperature resistance is low, the ambient temperature of the boiler site is high, and the fire detection probe is seriously damaged by overheating;
◆ Split structure, the overall spare parts are expensive, and the delivery time is long;
Solution
◆ Replace the original DURAG D-LE 703 fire detector with Safe-Fire’s W-FLAME series fire detector, which has stable performance and strong anti-interference ability;
◆ By adjusting parameters such as bandwidth, frequency, gain, etc., W-FLAME fire detector It can accurately reflect the burning condition of the target flame;
◆ The new fire detection probe has a temperature resistance of 85°C, a 40% increase in temperature resistance, and can adapt to high temperature and high dust working conditions;
◆ Safe-Fire's W-FLAME series integrated fire detection Specialized design, short delivery cycle and high cost performance.
